[Q] possible to adjust voltage supplied to 3.5 jack? - Sony Xperia P, U, Sola, Go

I like to listen to music so much. When I bought my SXS with information that the 3.5mm jack changed to CTIA standard, I thought that there would be no extend of compatibility with headphone form other companies. Of course it works with a wide range of headphones but not headset :crying: . Besides enjoying music the SXS need to function as a phone. It's very uncomfortable while I'm listening to music someone calls and I have to unplug my headphone to start answering.
I looked up some topics talk about this matter and could get the conclusion that matter as below:
////quote
The cause of the incompatibility: Sony Xperia S supply 2V (Volts) purely from an energy consumption perspective. The microphone in the boundled Sony Mobile headset is Electret microphones that only require a 2V feed. For other suppliers (e.g. IPhones headsets) they can use MEMS microphones that require a minimum of 2,7V.
In order for fully compatibility, Sony smartphones need to supply a minimum of 2,7V. This requires a feature/HW change
////unquote
All of us want to enjoy music and answer a call. Do we have no choices in stead of using sony accessories, using other brands products without mic or waiting for sony's coming phone?
I'm not a android programers but I simply think that we can adjust voltage supplied to CPU to make SXS runs with 1.67 MHgz so it is possible to adjust voltage supplied to 3.5 jack. Does anybody tell me i'm true? :crying: and is any developer dealing with the issue?
Thank you all

I don't think so. Get a CTIA headset, simple as that.

Of course I use a CTIA one, but the matter is that I cannot use the mic. Sony use different standard of microphone from the others

i tried every! headphone i have on my xperia P and it works just fine. (beats, apple, sony, philips and panasonic)
did you try cm9 (or 10?)?.
sometime it is just rom related, this was also a problem on the xperia play
i solved it with cm9

Thank you nickknoltus. I will try with cm9 as your recommendation. Are you sure that all headsets work well with xperia? I mean mic is usable for receive coming call and answer.

No, stock.

It's quite strange. I tried many kind of headsets but they didn't. Which ones do you have?

Sony stock, some Chinese noname crap and an HTC one, don't remember the model but it shipped with lower end phones.

Hi. I'm trying with CM9 rom. At a first look, it's very good. I haven't checked all functions but the headset mic still doesn't work.

Play Guitar through you phone app for Android?

Hi!
This might sounds silly but do you guys know if anyone is working on something like this for android?
http://www.youtube.com/watch?v=0Nod69aTzsM
An app that makes your phone to a small guitar amp?
The iphone version has been out for a while but i cant find any info on a version for android..
The company behind iRig have been speaking about a android version but i dont think they even have started working on one yet.
It would be a really nice application! To allways be ready to record without setting up the computor and stuff like that ya know, or to just sit in the sofa with earplugs and play some sweet solos and riffs without having your gf whine about the loud music..
Found this dude trying to make something close. http://www.youtube.com/watch?v=sz-9mxWa2VA
Just checking if anyone knows anything?
Best regards and thx for all the awsomeness!
/Patrik
This would be awesome, I would definitely buy it. It's like a Line 6 pod but much cheaper.
I hope they're working on an android version. Android needs better quality apps.
Also, it's more of a multi-effect pedal than an amp. Just letting you know
I actually sent then a message on youtube to see if they were working on one. This is what I got.
This is the Mac/PC version. If you look at our AmpliTube iRig playlist you'll find the iPhone version. We're currently looking at the platform but do not have any versions for Android.

Yeah, multi-effect pedal.
Imageing all the fine stuff you could do with it!
You could use it as an effect to plug in to your amp. (maby quite alot of effects, if you can make your own sounds. And with new developing you never have to buy a new effect-pedal again.. ).
A strummer for electric guitar in the studio/rehearsal place.
Play with earplugs on the sofa.
and so on...
I'll buy!!
it needs dedicated hardware don't forget (about 10 seconds in on the video)
your phone only has one 3.5mm jack plug...and you need to plug a guitar into it and an amp into it too.
also, what happens if you've got your amp turned up to 11 and then you get a phone call?

I've bookmarked that link
I am amazed that this can be done on the iPhone but not on Android.
There is another program called Ghettoamp on the market, though the devloper admits that there is still latency (he records, then processes the sound input). 20ms I think.

It should be possible...
Android phones definitely have the processing power to do this. The only real problem is you're input and outputs on your phone, there's really only one... the 3.5 mm jack...
But there's maybe a way around this. And I'm not an engineer or developer or genius of any kind I'm just saying what I think should be at least possible... Everyone knows AD2P Bluetooth right? You could get you're input through it.
You use the microphone of a bluetooth headset, but instead of the microphone, you get your input from you're amp/guitar/whatever... could it be as simple as soldering a headphone jack to the PCB connections on a bluetooth headset? Dunno but let's asume it's possible.
Then you connect your phone to the headset, and you've got input... Great.
The problem now is that I don't know what android does when it has a bluetooth headset AND a normal set of earphones... Does it play from both, does it by default choose, I don't know... Say you still get output from the headphones, you could easily get the output to any speakers, seems rather pointless to use the phone's loudspeaker... This part from bluetooth input to audio jack output will maybe need a modified audio driver or something...
Once you've got input into the phone and output out of the phone, you would like to have some effects and/or amplification right? That's the point isn't it? I know nothing about programming such things but maybe a few developers who do will stumble onto this thread and share their expertise...
Once again it should be possible, but for just anyone to do this it'll be very challenging, more likely and hopefully companies like Gibson or Marshall or Ibanez (their Japanese, and this seems like a Japanese thing to do) for instance will see the need for something like this, and get working on it... If they make something like that and it works well, it'll make a LOT of money... For instance after you've bought this device, they could SELL effects, to be downloaded on a sort of 'plugin-basis'. And once one company does it, all will have some variant of the concept. I know I'd buy this...
Edit: Read about the apparent latency issue that Android has... So I don't know if it's that possible just yet, maybe ICS has bettered this flaw in previous Android versions, one can only hope...
Sorry for refreshing this thread, but I'm curious if there is such app for android available right now?

You are thinking much too complicated.
The headphone jack of phones contains another pin for the microphone. A small jumper cable can be used that allows the connection of a guitar and headphones. Check out Amplitube iRig for an example.
(this type of jack is used so you can plug in a headset with microphone)
Bluetooth or something would be nice... but the latency wouldn't be, and that is exactly the problem.. Android has too much latency,
Look:
http://code.google.com/p/android/issues/detail?id=3434
Android is not capable of this because the way it handles audio is completely wrong. More recent devices have less latency but still too much. The problem lies very deep. It is a problem for game developers too. Please star this issue if you want Google to do something about it!

The Irig will work fine for this you dont need bluetooth aor usb adding yet another layer of BS to the audio streams round trip. however now that JB is out latancy is stitting around 10-12ms on adevice such as the galaxy nexus wich is completely usable (1ms of latancy = 1foot from your amp) so 12ms would be like playing 12 feet from your amp,
If you cant play like this then on stage will never work for you.
As a side note usb audio is apparently supported in JB as well now
There are now a couple of apps on Android that at least have a range of guitar effects. Delay Effects Plus (via headphone type cable) and usbEffects (USB OTG) both have an option to use Native Audio, so if you have the Galaxy Nexus running JB the latency is quite reasonable (50-70 mSec). If you have a modded ROM you may get lower latency without Native Audio option as they both read the buffer size from the OS. Of course for everyone else the latency is still an issue and varies from device to device. So to those that said they would buy .... please do!
This very issue has put me on the fence on what kind of tablet I buy. Cannot decide between note, and Ipad 3. The accessories and ItunesU has been one of the biggest attractions for me.
Litlle heads up: in their latest newsletter IK Multimedia (of Amplitube) post a few job openings, one of them being "Android App Developer"!
So they are at least working on something..

Sound Problems...

Hi everyone, I'm new here. The HTC Aria is my first android phone, and I had an iPhone before. I am having problems, the Audio quality is really really bad. It's not my music's fault cuz it's bad for everything. I am the only one having this issue or is every one having this issue. My phone is currently rooted and is running the Liberated 2.2.2 or something like that.
Was this a problem before you rooted and changed the ROM?
Also, you need to be more specific... is the problem with the loudspeaker on the back of the phone, the earpiece (talking on the phone), or when connecting something to the headphone jack?
What software are you using to play music? What headphones / speakers are you using? ( Just curious ).
With my Sennheiser HD 280 pro headphones I've noticed the sound quality isn't as good as my girlfriend's iPod or my creative Zen vision m. It's pretty good, but nothing spectacular. I suppose it's because those are two devices specifically made for playing music, while the aria is, above all else, just a phone. With the aria I usually prefer to use "cheap" skullcandy earbuds so that I can't tell the difference in quality.
Of course, your results may vary from mine.

Thanks for the Response guys! I was using the default Music player. But I am going to try CM7 now because it has the Equalizer function.
Ok guys, it's sorta fixed. I'm using CM7 2.3.4 and a Music app that was ported from MIUI. It's sorta fixed, now so no worries. Thanks for replying fast though guys.

I'm not aware of any headset with three button controls that work on Android phones. All single button headsets I've owned and tried have worked fine though.
Here's a link to a site I sometimes use to buy headphones from, with a direct link to headsets with mics and button controls. Unfortunately, many of them are made specifically to only work with Apple products, but like I mentioned, all single button headsets should work properly.

Even though their products tend to be overpriced, I currently use and recommend the Bose MIE2s. I also own the Klipsch S4s and enjoy their sound. There is a mobile version that's made specifically for Android phones as well.

Normally for music I use AudioTechica, which does not have a mic and control..
But if you want one, try the new Phillips O'neil branded "Specked"..
there are 2 versions though, one with Mic and one without....
With Mic version cost around 30 euros over here, but in US maybe it is cheaper....
It also provides an Adaptor which you could use for Nokia/Samsung mobiles...so it is a complete package....

my blackberry headphones used to work well on BB and on HTC Desire S.
by working well, I mean 1 press answer/end the call, long press redials the last number
when in music player, a press on the same button is pause/play.
on RAZR so far only long press works for redial of last number. short press activate voice commands, and play/pause simply does not work. Any idea how to revert to "normal"?

Well the working of the controls is strictly dependent on the interface chip used.... in that case, one particular control might not be completely useful into another phone..
Hence the new days headphones have minimalistic controls only.... and they do mention which phones it can be used with.....
the headphones with larger repertoire of controls are mainly bluetooth , since bluetooth is an open standard...

[Q] FM radio over bluetooth

I just got an S3 and I'd like to ask if it is possible to listen to FM radio over Bluetooth.
i connect the standard headphones to enable the FM radio and the only option is to switch output between the headphones and the loud speaker.
I've seen cheap chinese android phones doing that, there should be a way.
Any help would be greatly appreciated, help me avoid selling my new toy
Sorry to say but it won't work. The reason (as the app itself already accurately describes in the error message) is that your headphone's cables are used as an antenna for the phone's FM receiver.
FM antenna's are actually quite big (at least compared to other antennas) even when using the so-called fractal design because they use a very slow (roughly 80 - 110 MHz, compared to e.g. WIFI's 2400MHz) frequency. To save space, Samsung moves them to the hedphones on all mobile phones I know of.
I don't know if it still works on S3 (never tried) but on the S1, if the station is broadcasting with enough signal strength, you could cut off the plug of old broken headphones and plug it into the phone to use the radio.
Afaik Spirit FM (now paid in all versions) can override the requirement but you'll need to press your finger to the jack so you can receive anything... pointless.
Alternatively you could use an app for internet radio such as TuneIn; most radio stations (at least all around here) provide web-streams for on-the-go radio listening. However you should make sure you got a decent internet flatrate, I managed to chew through nearly 4GB just with music streaming this month.
Most countries seem to have abolished mobile data flatrates.

The OP understands that the phone needs the cord to act as an antenna. I think what they simply want to know is if the phone can then route the sound to the bluetooth device instead of through the speakerphone or the headphones.
Sent from my MB860 using XDA
d4fseeker I understand that the headphones should be connected since they serve as fm antenna. What i want is to listen to fm stations through bluetooth while the headphones are connected as bigb25 says.
TuneIn is not a solution for me since some stations I want are not available and cause I am a hiker internet is not always available where I go.
Maybe there is a fix or a different radio fm app?
OK quick test... plugged in 3.5mm - 3.5mm jack lead into headphone socket to act as the FM antenna and started the radio, selected sound to speaker and all worked fine. switched on Bluetooth headset no sound in headset, switched off sound to speakers still couldn't hear anything. Unplugged patch lead (this ends radio anyway) played an mp3from music player and sound returned to BT headset.
So unfortunately the answer is no you can't, as soon as you plug the anything into the headphone jack it cuts out the sound to any other device.
This may well be a mechanical switch within the headphone socket and so unlikely that there's a get around in a custom rom....but then I know nothing about roms

The latest Free version of Spirit can always be found at the top of post 1 of my Q&A thread. See my sig.
My cheapest ($80) test phone gets good audio AND RDS with no antenna. Ironically it's the best of 12 operational test phones I have. It's a Samsung GT-i5500 with the great, sensitive new Broadcom 4330/20780 family of chips.
But yeah, my Galaxy S and S2 don't do very well with no antenna. My Galaxy Note does better. Haven't heard from anyone with an S3 yet. They all have the Si4709 FM chip, which has positives and negatives. Internal circuitry etc. makes a difference too.
And I can thank the very positive sales response I've had from S2 and Note owners for being able to buy these expensive devices for testing. I'll do everything I can to make Spirit run well on S3 and hope to buy one soon.
I have yet to find a phone that does FM over BT, except for a strange very low quality mode I have working on some BCM 4325 based devices.
If the FM can be done in the digital domain, instead of the more common analog, then in theory it should be possible to do FM over BT.
But then again, in theory the Galaxy S and S2 hardware are capable of FM record (digital). Yet the audio libraries don't seem to support it, and I think it'd be a major/infeasible job to hack the libraries for it.
The Note and I think the S3 can do FM record with stock audio libraries. So I think FM over BT on these devices is feasible, at least with stock ROMs and/or using stock libraries.
But on non-stock ROMs like CM9, the Note seems incapable of FM record.
Basically, if the stock ROM and stock FM app don't support FM over BT, then I think it's not EASILY possible.
If it could be made to work, there's no reason why a phone couldn't have a wired earphone plugged in at the same time that FM goes over BT. This might "confuse" the audio system though, which usually sends audio over a wired headset if one is plugged.
Then again, it's also possible to have a plug that's partly inserted (or maybe even wired creatively). Enough for antenna but not enough to push audio through the wired headset.
Thanks mikereidis.
I tried the free version, it plays only when the headphones are connected.
Do you think you could look at the possibility to send output to bluetooth?

This dual active android phone does it: Star B79 Android 2.3.6 MTK6575 Smart 3G Phone 4.3"HD. I can not insert link cause of the ten posts limit but you can find it at aliexpress website
A colleague has it and I tried it just now and the quality is superb. And it is much cheaper comparing to the 730 Euro I gave to buy the SIII (greek retail price 32 GB version)
Actually this was the reason I switched from IOS to Android I mistakenly thought it was a default option in Android.
Also my ancient HTC diamond could do it with the help of a bluetooth utility but it woud often crash and quality was not good.

The Note and I think the S3 can do FM record with stock audio libraries. So I think FM over BT on these devices is feasible, at least with stock ROMs and/or using stock libraries.

Yeap SIII can do FM record

Thanks mikereidis.
I tried the free version, it plays only when the headphones are connected.
Do you think you could look at the possibility to send output to bluetooth?

Yes.
I have one person reporting success with my app on GS3 on CM9 June 19 now.
It only works one time though, then requires a reboot for the 2nd time.
This was with an experimental release I haven't made public yet.
I hope GS3's will be coming down at least $100 over the next month. $700 is pretty darn steep, even if it's got a leg up on the One X and One XL I bought recently for 570 and 500.

That's very interesting; thanks for the info.
There are a variety of relatively inexpensive Chinese devices that have unique qualities, such as FM on an Android tablet, or digital TV tuner, or FM transmit I think.
But these devices are not widely available, or popular I think, in most Western countries. Information, source code and custom ROMs can be difficult to impossible to find.
As for Android: the audio systems can be kind of a big complicated mess. I don't think I've ever seen a single phone with an audio balance setting, among other things. But at least some Androids have "over the air" FM, whereas iPhone's have never had FM, despite years of rumors.
i am thinking of using one of these dongles though I doubt about the quality

Kind of a drag to have a dongle hanging off though, in addition to the wired earphone for antenna.
There's been a lot of praise for the Sony MW600 Bluetooth stereo headset with built-in FM the last few years. Under $40 on EBay now.
I just ordered the apparent successor, the MW1 for $120 plus shipping the other day. It even has a music player built in, besides the FM and BT 3.0 support.
I need the A2DP headset because I think I'll be able to support FM over Bluetooth on some devices in the next few months, and I need something to test with.
MW1 seems interesting with many features but the price is ....

I will be waiting for the new version
Not an exact solution, but you can get bluetooth headsets with built in FM radio.
eg: Sony-Ericsson-MW-600-Bluetooth-Headphones

The headphone jack has a part that senses when a headphone is inserted (the metal
in the headphone plug shorts it. It seems like you could make a plug that connects
to the metal of the ground pin (for the radio antenna) but isn't "inserted" so the phone
won't disable using BT.
Anyways, only i9300 will support FM, there is no way to get FM working with the Broadcom
chip in the US S3's. http://forum.xda-developers.com/showthread.php?p=31576462#post31576462
I use a sony ericson bluetooth headset that has built in fm radio works well.
Model MW600havent priced them in a while,should be under $50 by now.

Sony apt-X support.

The lack of information on apt-X is ridiculous but I finally found something. According to the apt-X website, no current Sony devices support this protocol. This means that for any of you audiophiles like me, achieving the best sound quality on Sony devices is presently limited to wired headphones. This doesn't apply to headsets such as the Sony wireless headset pro, as pointed out by mrsatan. Just thought I'd share.

My sony bluetooth headphones use wolfson audio decoder which is arguably the best decoder around. I really dont understand what the big deal is with apt-X. Obviously there is some with hardware chips but it looks like their main draw is with software, which can be good or bad, Sony sound optimization is really good on Xperia S. They basically look like another vendor like Wolfson but I have never heard of them. Wolfson is awesome as **** when it comes to audio quality and my headphones are really good.

From what I understand the Wolfson DAC is hardware based in the phone, not in the Bluetooth transmitters/receivers. Bluetooth uses an entirely different protocol/codec to stream audio.. Once you stream via Bluetooth there is distortion. Not everyone notices it, but I do, and that could pertain to the type of music I listen to. That's why apt-X support is a better choice for some since distortion is eliminated. To each their own.

The wireless headset pro use Wolfson DAC since it is a standalone mp3 player as well. It definitely uses it even when streaming from the phone because their is a quality difference. There is no distortion on it because it doesnt decode before it streams it to bluetooth. I am a member of Head-fi.com and I remember before I bought the device we figured out what dac it was using and that influenced many to buy it. We were pleasantly suprised to see it using such a high quality dac.

Lol, this thread is in reference to stereo headsets that rely solely on the Bluetooth protocol so it wouldn't apply to the Sony wireless headset pro or similar devices.
Now I kinda want one of these Sony wireless headsets so I can keep my Sony phone, lol.

No current Sony products support apt-X. Your smart wireless headset still doesn't support it despite the conversation we just had, lol. That was the only point of my creating this thread.

if only we had an accessories section to discuss accessories. we should go and ask the admins
Also sad to see apt-x missing. It's a major buying factor for my next phone.
I have several bluetooth speakers that support it, so my next phone will.

I'm hoping future Sony products support it. There are a few different aptx-enabled BT headphones that I'm looking into buying. I currently have the Samsung HS3000 and wired earbuds but I want to go completely wireless.
