My old mobo decode yourself(freezing, rebooting bootlooping etc) so I bought another one and after home disassembly/assembly I discover that right earphone is not working. So I checked the trs and the trrs - two types of headphones and I receive this same problem.
I'm wondering that it is a jack port or mobo? Can you give me the right answer?
Thank you! : )
Of course I teardown three times too.

Hello,
Today I bought YC-A300 adaptor and soon after unpacking I realized that the device doesn't work properly. It occurs that 2.5 mm jack socket has two lines swapped - left audio with microphone input. Obviously the attached headset doesn't work as a result. Despite of this, other sockets work fine (i.e. ext USB for charging, ext USB for audio and 3.5mm jack audio). I would like to emphasize that the device is original HTC product. To give you better idea of this fault see connection diagram below:
Standard 2.5 / 3.5mm jack:
1. (tip of the plug) Left audio
2. 1st ring - right audio
3. 2nd ring - microphone
4. common ground
My 2.5mm jack is connected like this:
1. (tip) mic input
2. right audio
3. left audio
4. ground
Due to this problem I have two questions - am I alone with this or someone else also experienced such issue? And the second - has anyone tried to open the case of this adaptor? Obviously I have warranty for this, but my internet supplier wants to wash hands of it and local HTC service center needs ages to check if they can repair this (lol). Normally I could wait for weeks/months and argue firstly with my supplier and later with service center, but I bought this device for about 10 Euro (I live in Eastern Europe so OEM prices are lower) and I don't think it's worth the effort to fight with them. Since I'm an electronic engineer I could try to repair it myself, but firstly I would like to know if there are issues with opening the case (it seems possible to brake it during opening).
Thanks in advance for any replies.
Hi all,
to my great frustration, I've discovered that my SGS2 line-out / headphones jack seems to have a slack joint, i.e. if you turn a connected plug around its long axis, a crackling sound is heared in the speakers and at some angular positions the stereo signal will be reduced to mono (i.e. one speaker gos silent). With one device (mobile outdoor speaker) I even had no sound at all at when inserting the plug with the wrong "orientation".
Did anybody experience the same problem or am I just out of luck here?
I am wondering whether sending back the device to the retailer (Amazon) or directly to Samsung (I'm situated in Germany) will yield the faster round-trip time, any experiences here?
Thanks!
PS: I know this may be a stupid question but can somebody PLEASE tell me how to search for multiple keywords with AND logic in this forum? Tried "+word +word" and "word AND word" (without the quotes) but nothing seems to work.
Are you using the headphones that came with it? My better half went through 4 sets of the stock samsung headphones with her original Galaxy S and all produced the same issue of losing one channel after a matter of days/weeks. having the jack inserted to about 2/3rds is a workaround but not ideal as you still lose some frequencies and it's insecure... They're just a bit pony.
No, I used different kind of headphones, including Sennheiser in-ear headphones and a standard male-male audio jack connected to some bigger hifi system. With some jacks I did not encounter the problem, but most of them lost some part of the signal with some orientations: I persume that the manufacturing tolerance of the jacks also plays a role...
Anyway, it's definitely not a problem of the jacks but of the device since I tried it with the SGS2 of a friend yesterday and it worked with the same jack that made problems with my device.
I will proceed sending my phone to Samsung for repair, I hope that won't take to long *sad looking*, I am so used to it now, it's card to survive to weeks without it.
I had the same problem, all I had to do was insert headphones cable "HARDER" into the audio jack until I herd a "click" sound.
I was way to over protective of this phone when i first had it, and wanted to handle too much with care, forced the dam cable in, and "click", sounded like it snapped into place, the audio worked correctly without cracking noise or without the need to wiggle to cable get clearer sound.
Perhaps your friends SGS2 is already used to headphone being inserted, but yours not. Just add a little pressure until you hear clip into place.
If this doesnt help, then repair or return.
Thanks for the hint, but unfortunately I had the jack inserted to the very end, so this was not the problem... sent in for repair now, let's see what happens.
I have a fix for you i think!!!!!!!!
ok . when i got my s2 like 4 days ago (at&t usa version) i noticed that when i plugged into my aux cable in my car that it was low sound cracking more volume on the left side , very annoying . NOW FOR A SIMPLE FIX FOR SOME TO TRY! PLUG IT IN ALL THE WAY! i noticed when plugging it in i wasnt fully plugging it in . it should go all the way down FULLY! the sound is perfect once this is done . I HOPE THIS HELPS YOU !!!!!! good luck
Hello Dear Xda,
I am having a very strange issue with the Audio Jack. When I got my phone I used samsung headphones and they seemed to have worked perfectly. Now when I tried using other headphones - i.e. the ones that work perfectly with my other devices, it simply wont register. I put the jack in, but nothing happens. the music keeps playing. I thought its only that headphone so I tried others, such as my Car's cassette adapter still the same issue arises.
Now I tried my mothers phone which is a Galaxy SL and it works perfectly with all the headphones that wont work for me. then I decided to squeez teh headphone a bit harder and turn it around in different directions and it started to work a bit, with terrible quality, but it worked. and if i hold it into a certain awkward position you could hear the sound almost flawlessly.
I have came to the conclusion that my jack might have a problem. But I am not aware how to fix the problem. Cause it works perfectly with some headphones, but it wont with others. Does this requires full change of the jack, or can it be fixed by readjusting it somehow?
inb4: I have restarted the phone several times, changed to factory setting and even changed rom to no avail, so this clearly is no software issue.
Thanks in advance
Replace jack. Should be YouTube videos around/Google search might reveal how to do it, but in all honesty, if you're not competent with microelectronics (like me), take it to someone who knows what they're doing (local mobile repair shop). Shouldn't be expensive to fix as the jack is a cheap part, main component of the fix will be labour.
Hi everybody
Sorry for my english, isn't my native language
For some problems on my radio i had to buy a main board to KGL on internet and they sent me one "new", but no was so, it was repaired unit and had some problems. so i claimed to paypal to help me and while i was waiting for the answer kgl tried to help me to repair the broken mainboard and sent me the material that i share here.
finally my problem was on TFT board (1 resistor died) and paypal refund me the money, and today i'm very happy because now i can listen MY music after 5 long months.
Maybe we can see something that can be improve to get a better radio(sound, signals, etc) and is easy track the routes with this software.
i tried to upload the software to open the pcb but i cant, so the program name is PADS9.5, try to download it from google
https://www.pads.com/downloads/standard-eval-request
i call @Digo69 to explain us how to made the mod he told here http://forum.xda-developers.com/showpost.php?p=67892872&postcount=464
thanks
@7floor take a look
i had been looking on pcb file the bluetooth mod and i think is no needed, take a look on yellow tracks, the radio has done the mod, the problem is the kind of jack for the micro because the original mic jack is a 3 pins, which 1º pin is groud, 2º pin is the mic for bluetooth and tracks go to c32 and c32 go to pin 4 on bluetooth module (pin 2 pic) and 3º is mic for system (pin 3 pic), i only can see two separated ways for sound inputs.
maybe c144 do some modification on bluetooth mic, because it's connected to c32 (jumper) pin 4 on bluetooth module and ground
we only have to use a 3 pin male jack (stereo) and use an aftermark mic usin pin 2 + and pin 3- pin1 no connected (only for bluetooth mic in) or pin 1 and 2+ and pin 3- for both mic in
what do you think?
look

Can you ask for them to send you schematics? These are board designs, somewhat useful.
I have a problem with my package included headphone or my phone or both I don't know.
I wonder anyone got this weird bug or hardware problem.
This is the problem step by step:
I plug usb type c package included headphone.
I see small headphone icon upper side of the screen.
I open a music app -for example youtube-
I play anything video is shown and auto playing stops the video or music. Phone acts like headphone unplugged but its plugged anyway.
Small headphone icon doesnt show anymore but its plugged to usb port.
I touch the play button again and music comes out from phone's speakers.
I unplug and plug headphone again to usb port and music comes from headphone and little icons shows up on screen.
So this is the problem that I have. I need to talk about some experiment notes I have had.
I have never had this bug or problem with usb type c to 3.5 mm headphone jack converter. And also having same problem with making some calls or any kind of sound output situations with type c headphone. And the interesting part is I tried to record a screen video about this problem guess what... No bugs or problems when recording but its again shows up when I stopped the recording video.
Tell me something about this bug or problem. Anyone have this problem with phone. Thanks a lot already for your comments and suggestions and answers
I bought my Mate 20 mid April and I faced exactly the same issue with headphone. No matter I use the original one USB-C or USB-C to jack. I did not find any solution and returned the phone back to the vendor.

Hi!
I have the same identical issue. I bought a mate 20 pro and originale headphone works only if, after music starts, I unplugg and then I plug headphone usb c.
Have you find a solution?
Hi I too have the exact same problem. Has anyone found a fix for this?

I've had similar problems with my headphones, maybe not exactly. But hey, give it a try. Definitely worked for me. I say headphones because I had the issue with both the packaged headset as the Huawei ANC ones I bought later. Problem was an accumulation of rubble in the USB-C socket of the phone. And it got worse over time. Took a very thin item and gently cleaned the socket. Cleared all issues instantly. Substantial filth in the port. To check for rubble in the portt take a magnifying glass and enough light to check. Hope it helps. I thought after it got really worse and the cable would not even stay in the socket, I had to send phone to Huawei for repair but as a last resort I cleaned the USB-C port and now no more issues. Do be careful though.
I've not even taken those out of the wrapper since getting my m20p in December. Using Bluetooth without any issues on assorted headsets.

Same problem here, but only with the earbuds that came with the phone. If I use the adapter (which also came with the phone) with my old headphone, there are no problems at all.
no one has solved the problem of the original earphones that are not heard on the phone? I brought the phone for assistance with this problem and they replaced my motherboard. today I picked up the phone and the problem is still there. ridiculous. for you the problem is only with the original earphones or even with others of the type c?
up up please
The problem stopped occurring as soon as I updated my phone to 9.1.
