Noise Cancellation Modes - Xperia Z2 Q&A, Help & Troubleshooting

Since some of us kept wondering about what exactly we can do with the NC feature, here's the explanation of all three modes that we get:
Off:
NC feature is off, even when NC headset is plugged in.
Auto:
NC is activated only when music or video is playing with the screen on or off and when the screen is on but nothing is playing.
Always:
NC is always enabled, as long as a NC headset is plugged in, even if there is no playback.
We also have three intensity settings: Office, Bus/Train and Plane which adjust the strenght of the NC effect.
So what does this mean for us ? Basically, the auto feature allows to use the feature for music with the screen turned off.
But here's the the good news - the always on feature allows us to use NC without any music, simply to create a silent environemt for study, work, reading or suppresing those screaming kids on the bus etc. which makes me very excited as I hoped that this will be the case

What I'm curious to find out is whether the NC auto feature is tied to the walkman app or not.
I shouldn't be and I hope not!

In "always on" mode it's active all the time, even if nothing is playing, so I guess it's safe to assume that it is system wide. I'll try to verify that.

Sound randomly turning off?

Anyone else experience this? I have had it on FM radio, Music player and Google Listen, they just randomly stop for no reason. I had a similar issue on a Desire S so might be a 2.3 issue
Yeah if you have motion turned on, the FM radio and other music functions will turn off when you turn the phone over. Simply go into Settings, choose Motion and make sure the option called Turn Over is unchecked if you don't like the feature. I personally don't like it myself as my phone moves around a lot while listening. If that function is not checked, then you may have a problem with your phone. My guess is that its turned on though. I turn off all motion as I find it may chew the battery a little more plus I never use any of the tilt or panning features

[Q] Xperia P - Audio + wi-fi = electrostatic noise?

Hi, xda-developers!
I'm curious to whether my phone has something faulty going on, or whether it's the same for everyone. If I decide to load up a sufficiently long youtube video (anything that requires you to keep buffering with the network, really), if I decide to watch it during this time, I get a static noise in the background. The noise volume level doesn't change when you lower the media volume, until you have made it silent, and it keeps making the crackle for a few seconds, then stops.
Android 2.3, prerooted image.
Should be added that I have to use my inear headphones to make it audible, it's not that loud. Found other people having the same problem, unable to link since I'm only at 10 posts, but can quote that:
Yes I've had this issue too, it's especially noticeable when listening to music via Connected Devices (i.e. over DLNA) but not so bad in Music Player. This might suggest Wi-Fi interference possibly? I might do some tests with the phone in Airplane mode...

Periodic noise during music playback while WiFi is on but not connected

Trying to determine if this is a software bug or a hardware problem. Looking for some additional people to test and verify.
ISSUE:
While listening to music, I hear a periodic, short duration, low-volume burst of static. This only happens when WiFi is on but not connected (searching for network to join). This also only happens with headphones (at least I have not been able to hear it over bluetooth).
NOTES:
I have tried both the HTC stock music app to listen to music stored on the external SD card and Google Play Music to stream data from the cloud.
The period of the noise is 15 seconds when on a Jelly Bean ROM (I have tried both MeanBean and xHausx's stock ROM. When I was on MeanROM ICS, the period appeared to be 17 seconds.
The duration of the noise is 1/4 second or less.
The volume of the noise is very low. I recommend trying to reproduce the problem with very quiet music.
Wifi must be on and scanning to hear the noise. With Jelly Bean, the WiFi scanning interval appears to be 15 seconds (I did not check the scanning interval when on ICS). I recommend not being near a network that you can connect to when testing this.
I am S-OFF with the original LazyPanda HBOOT (1.12.2222) with the latest firmware installed from xHausx's thread.
BACKGROUND:
Here are some posts where this issue has been discussed in other threads:
JustinChase's first post regarding the issue in the MeanROM ICS Thread
Follow up later in the thread: #1, #2
Continuing discussion in MeanBean thread​
Thanks in advance for any testing you can do!
I have the same exact problem even connected to WiFi. As long as I have WiFi turned on I can reproduce the static noises you speak of on both stock rooted 4.1 and meanbean roms. S-off also :/
Sent from my EVO using Tapatalk 2
I also have the issue, but only when wifi is turned on, but not connected to a network. If I have no network remembered (nothing for it to try to connect to), I don't hear the problem then.
The noise is a static, crackling noise, which sounds like 'machine noise' that I also hear when I'm listening to my desktop computer with headphones thru the crappy motherboard connections. On the desktop, whenever I move the mouse wheel, or put the system under load, I hear 'machine noise' thru the headphones, likely related to poorly designed/shielded onboard audio.
This makes me think if might be hardware related, but the fact that it only happens when wifi is trying to connect to a remembered network makes me think it's software related.
The noise is always the same volume, which isn't very loud. If you listen to your music at 1/2 or higher volume, you will likely not hear it, but if you listen at about 1/4 volume, or lower, it's a pretty loud and very annoying noise. I almost always hear it at the end of a song, but hear it throughout songs also.
I'm s-off, so don't really want to go complaining to Sprint about it yet, but since it seems only a few other people have reported the same issue, I suspect it might by phone specific.
I would really appreciate anyone/everyone testing this and providing feedback, even if it's 'I don't hear this, you're crazy', at least I'd know
To test, make sure that you have a wifi network remembered on the phone, go to a place where wifi cannot connect to the network (or any other network), then play music with the stock music app (the red musical note icon), make sure the volume is less than 1/3 and you should hear this noise within a minute or 2. Some have reported every 15 seconds, but I'm not sure I hear it quite that often. If you make it thru 2 songs with no noise, you probably don't suffer.
Thanks, looking forward to some feedback
Hmm... Very odd. I might have a little input or it may be completely unrelated.
Are you guys with this issue using PowerAmp music player (i use that, it is AMAZING).
Anyway, I noticed that while using any global beats addins, I usually get a weird staticky noise through my headphones... BUT, this only happens while playing a song and another sound comes up. In example, I am playing an MP3, and I get a text message, or a low battery warning. When the other sounds come into play, it disrupts the music playing, and the notification doesn't even make its sound; just the static interruption where the sound WOULD have been. A fix for this, is to enable [maybe disable? not sure which is the default setting, but just uncheck/check depending if its on or not] the Direct Volume Control option. Doing this allows me to hear the other sounds while playing the music with no interruption.
Now, to get on board with the OP who has this problem on WiFi only. Perhaps it is the same scenario as myself. Maybe your WiFi is giving some sort of SU notice from the makesh that the WiFi mod asks root for.
Sorry if it sounds a bit confusing... But hope it helps!
EDIT: After reading some posts above, I see the problem comes in even with the stock music player. Idk, I still think it has something to do with MusicBox/DSPManager/Volume+ and the WiFi SU notices

That could be a bad port... Or it may be an IRQ problem If you feel comfortable playing with your BIOS on the PC, look into your IRQ settings
Some new info:
I clean installed MeanBean 0.6, connected to my home WiFi, then went to work this morning. Now that I'm at work (and not connected to my home network), the period of the noise is back at 17 seconds. I went to the WiFi settings and deleted my home network settings. Now the noise is at 15 second intervals. The volume of the noise also seems quieter.
I connected to my work's WiFi (they are finally letting "non-corporate controlled devices" connect to the network) and the noise is gone.
I'll have to wait until after work to retest the interval with a remembered network present.
Yesterday, when testing with a stock ROM, I only tested when I had never connected to a network before. So the period may not be ROM or OS version specific.

I have only tried the stock HTC app and Google Play Music. I have some tunes on the Amazon server, so I'll try that one later today.

I don't see the makesh app looking for root when on a Jelly Bean ROM (it doesn't show up in the SuperSU logs either). I wonder if HTC changed that in the 3.15 update.

Where might I find this setting you refer to? As you noticed (after you wrote this), I'm only using the stock music application, and can't find this setting anywere. I suspect it's in the PowerAmp player, but wanted to verify, so that I can try adjusting it. FWIW, I do hear the quiet notification noise while the music is playing (which used to stop the music on ICS - this is MUCH better).

I'd like to 'fix' this issue also, but it's been a LONG time since I've worried about IRQ issues. Windows 7 (and XP?) deals with IRQ issues well, so I haven't seen any conflicts in years. What in the BIOS might I be looking for, and how might I adjust it to try to eliminate this issue? I'm plenty comfortable in the BIOS, but the only IRQ settings I remember are related to forcing it to use a specific IRQ, but wouldn't know what to try changing for positive effect.
I'm plugging into the front audio port of the machine, which connects to the motherboard via a HD audio connector (if I remember correctly). I believe I have the same noise issue when connecting to the audio out on the back of the machine, which is directly connected/part of the motherboard. In fact, I've heard these 'machine noises' on all of my machines for years, so just always assumed it was a symptom of the lower quality audio connections. However, I'd LOVE to eliminate this issue also, if possible.
Sorry for the off topic
This sounds like it's just poor shielding somewhere. I believe the wifi antenna is near the headphone jack so it's probably causing some interference there.
Exactly Haus. Try different headphones or speakers. You could for your headphones get THIS then run a couple of wraps around it through the center near the phone jack, and see if that helps. For speakers the signal could be coming in from many places (power input, signal input, with in audio amp, or the speakers themselves. Now if the sound is coming from the speaker inside the phone.. Well you have much bigger problems than a ROM.
I have the static issue when streaming over Bluetooth with the screen on, wifi on or off, on both stock and custom roms. Turn the screen off, no static. Also, Bluetooth disconnects at random if I leave the screen on and will not reconnect until I unpair and repair with my stereo.
It has to be an issue with jb, as I've never had this issue until the update. Fwiw I'm thinking connections optimizer (on or off) has a hand in this issue.
Think I'm having this too
I was noticing this today on wifi. It would make a crrrik like a cog sound every so often, at first i thought it was the song, then when it did it on the next two I found this thread. It was not just 1x 2x per song it was almost on beat at times. I heard it probably 30 times in 30 second song. Another thought was some file/notification was making the sound in the background.
Turning wifi off so far has resolved problem. It was really annoying. I don't think its an antennae issue since its the same noise each time exactly (including duration) about a .25sec noise. Thinking of antennae interference its usually a scratchy sound that is intermittent duration some long some short etc.
It was extremely unbearable as I listen to the lowest setting on the phone with beats off.

[Q] Annoying automatic play when bluetooth is connected

Whenever I connect my phone to the bluetooth of my car, Poweramp player starts playing some random audio files that it can find on the phone. And typically would not shut up until I explicitly turn it off. The same was happening with my old phone (Droid Incredible) although not sure if it was the same application or some other player.
Is such a behaviour application-specific or is there some global way to prevent any programs from starting up automatically when bluetooth is connected?
At first glance I do not see that in Poweramp settings such a behaviour is configured or that there is a way to disallow it.

There is an option under Poweramp settings for "Resume on Headset Connect" and "Resume on BT A2DP Connect". Both under the headset menu in settings. Have you checked those to see if one might be causing it?

Both options are unchecked and if I read correctly they should be unchecked if I do not want automatic play.
I'll try to check them and see if it helps.

That's why I think there should be some global solution not specific to any application.
Perhaps, one can somewhere choose which application fires up when bluetooth is connected?
At first glance I do not see such an option in bluetooth configuration...
does anyone have a solution on this yet?
Try this:
1) Download Greenify (free).
2) Add the app(s) that automatically start to Greenify.
3) Test.
Greenify puts apps into a "hibernate" mode that disallow it from running in the background until you manually click on them to open. This is meant to help your phone by saving battery that those apps would use, but I could see it being helpful in your situation as well.

Eventually I used a hammer: I have frozen the offending application in Titanium Backup and it no longer bothers me when the phone connects to bluetooth. Of course, the downside is that I cannot use this application at all now but it was so annoying...
Before that I tried to use llama to kill the application automatically when connecting to bluetooth but that worked only in about 20% of cases.

Just tried Greenify. The free version does not "greenify" system application like google music and apparently I was wrong that it was poweramp. I have not tried the paid version yet, not sure if it is worth buying. Back to the hammer solution for now.
I'm fairly sure the "donation" version is the same.
If you're willing to pay for a great app with many uses, then buy Titanium Backup and use their Freeze function to stop Google Music.
My CAR does this. There is a setting in the bluetooth menu of my car called "Auto Play." When turned on, the car will start playing music when I get in the car, when off, I have to manually turn on music.

The free version of Greenify claims that greenifying system applications is an experimental feature of the donation version. I have not tried the donation version though.

I found this at pioloteers.org (Honda piolot forum):
"I have Samsung Galaxy and from what I read on the net it's a big annoyance for a lot of people. It isn't Pilot related, but is frustrating for a lot of folks nevertheless. The solution is to disable auto play on the phone as hollowpoints suggested. Unfortunately, not all android audio players have this setting. The one which I use – PowerAmp – does have it and I was able to disable it. After that Android stock player started auto-playing and you can't disable the auto play on it, so I had to uninstall it. Now the problem is solved."
I have a 2012 MB GL350 and the option is in the media interface settings.

Low voice guidance on navigation with music???

Hey everyone, I've been trying to figure out why sometimes the voice guidance from navigation (both Waze and G-Maps) over bluetooth kicks in extremely low while other times it doesn't. I've checked volume settings in the phone and the app itself, but no dice. I've been experiencing this since I was using my Note 3 some months ago, but it's gotten more annoying as of late since I've been riding my motorcycle more often. Without having the bluetooth audio kicking in strong enough to my helmet, it's impossible to navigate. Again, sometimes it is fine and other times it isn't. I don't know what sequence of events takes place for the volume in navigation to fade. This also happens with all the music/audio apps I use (Google Play, Spotify, Pocket Casts, Audible, and Songza). Has anyone else been experiencing this? And if so, have you been able to resolve it or at least know what actions cause it? If I can at least prevent it from happening, that's just as good to me as fixing it. Thanks in advance!
In addition, it isn't dependent on device being streamed to. It happens with my helmet, car, BT headphones, and even soundlink. You may be wondering why I was driving connected to a Bose Soundlink; merely for testing purposes. I wanted to create all the possible scenarios for this. I never bothered to try it using wired headsets because wired isn't an option for while on the motorcycle. It wouldn't be so bad if I could see the screen while riding when the volume goes low on me, indicating directions are being announced, but that's only possible at night; not during a bright and sunny commute. Thanks again!

I'm having the complete opposite problem..I need to find a way to turn navigation volume down while listening to music or listening to Audio books..Navigation comes in very loud in my F150 over bluetooth..I do notice when i'm not listening to any other audio and navigation kicks in it kind of fades in.
