Hey guys,
since I have changed the sound module for the "DSP" Module, I have experianced this weird issue.
Almost every time when the device leaves the sleep-state by turning the ignition on, the subwoofer doesn't receive any signal. It does turn on, but there's no sound from the sub. It only comes back, when I play with the subs settings. For example, if I mute and unmute the subwoofer, it works again.
Right now I'm running the modded DSP app, but the issue was apparent with the original version as well.
The unit is a Xtrons one. PB7939BIP PX5 running Hal9K 3.7.3. But the issue remained with other versions as well, so I don't think that the problem lies there.
I have read about the same issue from some other people on Facebook, but no solution so far.
Right now I'm thinking of a script that runs in the background to mute and unmute the subwoofer on startup. But I don't know how to do that, I've decompiled the MTCAmpSetup.apk's but it's very hard to understand how it works. So if there is someone who knows how to control the equalizer programmatically, I'd be glad for your help.
Another approach would be a script that does nothing else then starting the equalizer app and touch the mute button twice for you. But that requires some permissions that are basically impossible to get without root, so only rooted users would benefit from it. Also I don't like that approach.

All,
I noticed a couple possible defects after upgrading to 3.1 manually.
1. When playing audio from certain applications (XMP for Android for instance) The Audio cuts out shortly after the screen turns off, and then halts for a period of time before coming back shortly, then cuts out again.
2. Once you turn the screen back on, there is a distinct crackling in the audio.
Workaround:
1. Turn screen back on (get the crackling)
2. Unplug the 3.5mm audio jack
3. Play music from the speakers
4. Plug back in the 3.5mm audio jack
Anyone else seeing these issues with other audio applications?
Yep, I had the crackling and long pauses start happening today after the FOTA update.
Seems to happen (more often?) when applications interrupt an audio stream. For instance, listening to music and get an IM or email.
Yeah I had issues with this as well afer updating to 3.1...I saw in another thread that doing a "hard reboot" will fix the issue and has seemed to work for me so far. Hold the power button down for 10-15 sec until the unit reboots.
same problem
I have the same problem as well. The audio stops functioning properly when the screen times out or when I lock the device with the power button. The weird thing is that this behaviour is not consistent for all apps.
For example, "Music" stops only at the end of the song. From the "3.1 ROM issues" thread, other users are experiencing this as well. In contrast, in the apps "Listen" and "Audible", almost as soon as the screen goes off or I lock it, the audio stops, starting after some 30 seconds, halting again after 10 seconds. It repeats this cycle a few times and then stops completely. If I lit the screen by hitting the power button, the audio resumes with crackling noises as mentioned in the original posts.
Also, hard reset didn't work. I am tempted to do a factory reset except that I don't really know what's going on and I don't know if that'd fix it!
UPDATE: I found the following workaround solutions:
1- Winamp works flawlessly for songs, not a peep or hitch!
2- BeyondPod is working fairly well for podcasts. (It has paused once after 11 minutes so far.)
I did the fota update.
and I've the the crackling. Sucky.
me too. Hope they get an update out to fix this asap. Extremely annoying bug.
Would like to add I am also experiencing this issue although mine didn't start till a couple days after the update to 3.1. A hard reset works for a little while but the issue eventually presents itself again. Might be due to a caching issue with the music player?
Anyone try another music player?
I discovered the crackling noise problem last night.
At first I thought the FLAC songs were recorded from a dirty vinyl record.
I also discovered the problem where the Music app does not continue to the next song when listening with the screen turned off. How stupid is that.
These are two big problems that ASUS needs to address ASAP.
I am already annoyed by the pop sound when turning the Transformer on and whenever any sound to the speaker (Headphones are fine) is played after a long pause.
They must have used a really cheap sound chip in the Transformer.
Yes I can confirm the same problems with google listen. Have tried the hard reset but it doesn't really help very much. Things worked fine after the restart, but as soon as the screen turned off, then the audio paused, and began to crackle, then more pauses. It is almost as if some part of the system is in some sort of low power mode and is not able to feed the data at the required data rate...

I believe this could be exactly the problem. I have not yet gotten my TF, but looking forward to one greatly. However, I get exactly this problem on my Galaxy Tab 7" WHEN using setCPU to add a profile that scales the CPU down when screen is off. It sounds to me as if ASUS has added some sort of governer/scaling that does this. I could be wrong of course This is just based on reading, and personal experience

Yes. I get a lot of weird little problems with the Tab 7'' when setCPU scales clock speed down too far, including random reboots. I guess that's the sacrifice Asus made to give the TF such a tremendous battery life.

I don't know about "tremendous"
More like pretty good...
i can confirm that i have this issue using google music app. I previously purchased PowerAMP (arguably the best android music app) and no problems whatsoever when the screen goes off.
I do like the google music app as it seems like a truly lightweight player but its still in beta stage and needs a bit of work.
I just discovered something. The problem does not occur for my Transformer when the unit is plugged in!
So it must be power management problem, the question is how to fix it?
Hey guys, loving the xda forums btw, much love. I have a acer iconia a500 16gb, and same problem here:
Using Acer_a500_4.010.13_com_gen2
The default Music player is buggy and crashed fairly often, the audio stopping when screen turns off and stopping intermittently is also present on iconia with the default music player and the others as well.
The audio crackling is also present under same conditions.
To add insult to injury, sometimes when i connect a headphones the speakers dont turn off. And if i play with he "dolby mobile" settings, the sound on my headphones get really tinny untill i unplug the headphones and plug them back in, or i reboot the sys in some cases.
I just thought I should add to this thread that I have the same problems on my Acer Iconia A500. It consistently only finishes the song after I turn the screen off then it waits MINUTES to start the next song. I only occasionally have problems with the crackle sound. I had the crackling a lot when I first got it but it doesn't seem to happen as often any more. It doesn't seem to happen when I use doubleTwist but I really wish that the STOCK APPLICATION (which I like the best) would work...
Is there ANY way to fix this stuff? I mean even downgrading to like 3.0 or something. I like to use my tablet to play on my stereo system and I don't enjoy having to effing go back every time I want to play the next song. I also don't want to leave the screen on all the time and murder the battery.
I have the same thing happening on my A500 (running the ASUS PRIME ROM, though). When the screen turns off, anything audio related gets really skippy.
apparently there's some sort of setting build in for the cpu to underclock to the point of not being able to continue running the music application when the screen turns off. (that's me guessing it could be wrong) It always happens with stock music app though it didnt happen when in 3.0.
I installed winamp and doubletwist and both played nonstop.
Also i noticed that if you had music in your external sd and you open music app (also happened with winamp) and remove the sd the applications wont work anymore (thy always fc)unless you install the sd back (that is if you had your music library in the sd even if you also have it internally)
I tried moving the music to the internal storage but the error persist. the only way to get rid of it is formatting the tablet and passing the music to the tablet before running the apps. However if you install the sd and you happen to have music and music app open, youre screw again.
thats the error ive been having and im stuck with a 16gb sd in the tablet to hear music, (which i find it sucking cause my tablet is 32gb)
any suggestions?
Hi. I have the inspire. Its rooted and has the new 2.3.3 rom. My problem is that when i try to listen to music it skips, changes songs, opens voice dialer and then on one instance it called someone. I reinstalled the rom, restarted the phone, but it still persists. I have an idea it might have something to do with the headphones being inserted. When it was doing this i took out the headphones and plugged them back in and it played music just fine for a few minutes. any ideas?
EDIT
I just noticed right now that the icon changes from headset to headphones. Right now im listening to it and it playing just fine as long as the icon is set to headphone.
Edit 2:
Well i found this "Hey. I'm dealing with an annoying behavior, and I'm not sure if it's by design, or if there's something wrong with my phone.
When I plug in headphones... everything goes wonky. Specifically, the phone seems to take feedback from any pressure (usually accidental) I apply to the headphone cable. If I push it one way, it goes into voice command mode. If I push it another, it redials the last call I made. And other such along these lines. Why is it doing this? Is it by design, or is there something wrong with my device? How do I make it stop? Every time I jostle the phone while trying to listen to music, I have the phone annoying redialing my last call, going to voice mode, or otherwise interrupting what I'm doing.
I got the feeling, from one of the apps I was playing with, that this may be something called "headset commands," but I haven't been able to find anything else about that. "
Its a diffrent phone but same issue. I tried wiggling my headphone jack around a bit and found that the icon changed to headset. So ill leave this thread here for anyone having the same issues, as i couldnt find anything for this issue with the inspire forum.
I had the same problem on CM7, turns out the phone was recognizing my headphones as a bluetooth headset with built in controls, and it was confused thinking it was getting signals to skip around and change songs. I fixed it by installing a widget called Headset Blocker from the Android market, once I enable it everything works well.
Thanks! now my world is ok.
Hi all,
ICS 4.0.3
Ver. 3.32.707.10
I was wondering if anybody else is encountering similar problems.
Ever since the ICS update, my music player, podcast player (beyondPod) and e-book audio player have gone crazy.
I cannot understand the logic behind it, but the player either stops, skips, pauses, jumps... u name it. Not all the time, but (please do not laugh!) when the car door is slammed shut.
It got me thinking. Is it the shock or the vibration? Tapping or gently bashing the phone does not disrupt the player. Only door of the car closing. It happens every morning and every night when someone gets off the car before me.
Rebooting, taking battery out, clearing out some stuff from my Micro SD... simple stuff to eliminate causes have had no success.
Only rebooting the phone can solve the problem. Force closing the app does not help.
I was thinking that after a heavy days use, maybe the RAM was running out, bu the problem starts even within 20 min of reboot, with no other unnecessary apps running.
I am using Jays headset app since my headphone has that button that allows me to stop/play skip and volume control etc. This has nothing to do with it? I have had it for a while since Gingerbread...
If it were apps from the market that was problematic, i can understand. But since this affects the stock music player as well as other audio related features, I am baffled.
Anybody else? Suggestions?
Found the definitive cause. But still have no solution.
OK guys and gals...
I had my podcast player and stock sense music player do crazy stuff on me, ever since the ICS update.
Maybe the scratched paint is the cause of headache for some people, and covering/insulating it may relieve it of problems, but my feeling is that for quite a few that have posted on this thread, their reasons of malfunction differ, and in fact, are on the same boat as I am.
Please read my post which is the link below to understand the full symptom.
http://forum.xda-developers.com/showthread.php?p=24511005
I am not sure if ICS update from GS is related to this problem directly or indirecty. All I know is that I had a happy sensation until the update OTA.
Here is the reason why I know that neither the paint or back cover of sensation is the cause of skipping/jumping/stopping/calling last contacted....
I tried the experiment with the back cover off, but I could not replicate the problem, thus no paint chip, back cover or short circuit of any kind is the answer.
So, by method of deduction, with the cover off, I tried wriggling the headphone in the socket to see if that had any effect. None. I tried plugging and unplugging. None. I tried using the remote button to control the music app and the podcast player. No problem. The play/pause/vol up and down etc all worked fine. I even uninstalled the jays app and tried. Without the app, the button on my headset does play and stop, answer and end calls. It got me thinking, and the environment it caused the symptoms only could point to the mic on my headphones.
And guess what? It is the bloody Microphone on the headset. I bet you there are some of you with this problem using the stock headset supplied that have built in hands free.
Basically, the pressure spike caused by slamming of he car door, is the same effect as blowing into the mic of the headset. And once this is done, the only way you can stop is reboot.
Since there have been no posts on this thread, and while I was hunting desperately for answers, I came across a different thread. Similar symptoms. I posted there too, so u might want to take a peep.

Weird symptom. Possible solution? (Apart from using headsets without mic)
I have the same problem with my Sensation after i flashed the ICS. I have flashed two different custom ICS and with both i had the same problem. The music app goes crazy. I haven't find any pattern on what is that that cause the music app go crazy. When I touch the jack of the headphones (the original headphones of the Sensation) the app start forwarding, skipping track pause, etc. Also the same happens when i put the phone in my pocket. I haven't found any solution but maybe is the signal from the microphone as you said. When i shake the jack i think that signal noise i created and makes the app go crazy.
I hope someone will find a solution soon.
I just found a way to hear music in my ICS Sensation. I just disabled the default music app in the app settings that comes with the rom and i have installed the ESfile explorer which has its own music player. I am using ESFileExplorer's music player and i don't have problems till now...
Hope this is useful for someone.
I think issue is software related. Look here:

Does it happen ONLY when using headsets? I have the same problem, but is caused by the jack connector (only in ICS). It randomly sends signals that the phone understand as multimedia commands. If you remove the headsets and play the music with the speaker, no problem at all.
Crap.
Hey
Recently brought a xtrons head unit
Seems to work fine but there is a strange issue
The volume on the radio is very loud and have to only have it at a quarter at most but in any other app (tried bt music and Spotify) the volume is very low and I have to have it at its highest to get anything usable out of it.
Can't see anything in the settings for it. Has anyone encountered anything like this?
Cheers
Try first and go to the factory settings. On the first page I mean you find the volume settings for radio, system, Bluetooth and something else. Take a look that every entry are close together.
In my case the voice for navigation was to noisy. I've set the system volume up and it was fine.
I've been using Viper4Android half a year, but one week ago I decided to push it further with DDC and everything (Making my own profiles for headphones).
So my DDC profiles and others work fine, but sometimes an extremely loud white noise starts to sound (it hurts). It happens when I press play to listen to some song, and instead of playing it, the only thing that sounds is that painful noise. It also happens when opening any app, and what is weird is that it also happens when my headset (bluetooth) is not connected, so it sounds through the phone's speaker, and it sometimes happen when i'm in classroom so it's embrassing sometimes. I would say the problem starts when I change the source of sound, for example when moving from spotify to youtube.
To stop this, the only thing I can do is turn on and off the master power button in V4A app, or restart the phone. Android's volume slider does nothing, by the way.
My driver version is 2.5.0.4, I've got neon enabled, audio format is supported and sampling rate is 48KHz. I'm using Xiaomi mi A2 with the lastest version of android, got the bootloader unlocked and rooted via magisk.
This is the first time I post something here, then sorry if there is some thread about this bug already, I've been searching for it before posting.
(Edit): Tried to download new version (2.7.1.0), and still having the same issue.
