[Q]Audio Fix for CM10? - LG Optimus Black

I've found several topics about issues with audio with our OB, but no one of them is solved, you can see here, here, here, [URL="http://forum.xda-developers.com/showthread.php?t=1844338&highlight=audio"]here [/URL]and here.
I was looking into XDA another solution for CM10, and tried many but with not success, between those Apps for improve the audio I installed:
-xLoud (from PimpMyRom), it doesnt work, not even appear the app installed in my device.
-DspManager, it doesnt work or in my case I can't note the difference.
-And others like replacing media_codec.xml.
I saw many Dev's talking about a better sound in 'their' ROM's, could you help us/me with this issue/bug/whatever it is?
Excuse if my explanation is not the better.

How to turn off Shutter Sound for Camera in Cyanogen 4.1.999?

I searched the forums for this and could not get any help on this. Is it possible to turn off the clicking sound for taking camera shots? I went to Settings, but there were no options for this. I am fine with the camcorder one, but find it irritating and noisy when more discretion is needed. Thanks
Two possible ways, although I have not tried either.
1. There are a couple apps in the market that are supposed to do this. Never used them and don't know about Donut compatibility.
2. Replace the actual shutter sound file with a blank sound file. I've seen this discussed in some old threads on here, so you should be able to find instructions with a search.
No 2 is your best bet.... quick and easy..
Also if you just put your phone on silent/vibrate mode that will shot the sound, at least it does for me.

Thanks so much for the advice. I think number 2 is the best answer I'll try to dig up the instructions.... hopefully it is searchable. Thanks again for everyone who chipped in

[Q] Problem with music playback on CM7 Stable

Before I ask my question, I just want to let everyone know that I have searched and searched and searched for the answer to this before posting. Please don't be a troll unless you have a link that helps me. There are thousands upon thousands of pages and unfortunately xda's search function leaves a lot to be desired.
Now, here is my setup:
emmc CM7
Kernel OC'd to 1.1 ghz
DSP equalizer enabled
MortPlayer Music
What I get is a fairly regular skip/pop whenever I play any song from my music collection (mp3/m4a, mostly). Sometimes it will go almost a whole song without skipping but very rarely. From my research I do know that this WAS an issue with CM7 pre-stable release, but now there seems to be no discussion about it. It's not listed in known issues as far as I can tell so I thought this issue was no longer, well, an issue.
Here's all the things I've tried to get the music to work.
1. I dropped the kernel down to 800 mhz, thinking it may be an issue of my Nook not handling the OC'd kernel. Same result.
2. Flashed back to CM7 stock kernel. Same result.
3. Changed music players (stock, Meridian, cubed). Same result.
4. Made sure the files were not corrupted by copying the files to my phone (EVO Shift) and playing them. They play perfectly on my phone.
5. Disabled DSP thinking perhaps I had the level set too high and it was peaking. Same result.
6. Moved music from external storage (sdcard) to internal storage (emmc/My Files/Music) thinking that my class 6 card wasn't being read properly. Seemed to fix it for the first song or two, then same result.
7. Flashed phiremod 4/13 version, which again, seemed to help at first, then I got the same result.
8. Added (then removed) Auto Killer Memory Optimizer thinking that perhaps memory was getting low while I was playing music. Removed it thinking that maybe it was constantly trying to kill the Music app. Same result with or without AKMO.
9. Disabled the keep home in memory option in CM Settings thinking it was straining the system. Same result.
10. Dropped performance settings in Launcher Pro thinking the same thing as #9. Same result.
11. Switched launchers. Cm Version ADW, ADW EX, LP, Launcher7, Zeam, the launcher I use makes absolutely no difference.
I'm sure I've tried a few other things that I can't think of, but that is about it. What bugs me about it is that even if I'm not doing anything else on it, i.e., I just let it set and play music, it still skips. Even if I'm not performing other tasks such as surfing the web or playing a game. The other strange thing is that youtube and even flash video in the browser work flawlessly, so I really don't understand what the problem could be. I do know that a while back when the video issues were being ironed out, DSP was broken, but I thought that was fixed by rc4. Flash would presumably take up WAY more resources than the music player, why don't I have any problems with it? Would it be a problem with the audio codecs for mp3/m4a?
I'm really stumped here guys. My hours of searching have proved fruitless, so hopefully someone will have the elusive link I'm looking for. Thanks in advance for any help I receive.
I have the same problem. Anyone found a solution for this?

Thank you dalingrin. I'll make sure to check it out. You and the other devs here are doing a great job. I'll be sure to donate the next time I get paid.

If you don't want to wait the DEV Kernel topic has a ALSA update as well as an experimental 4/13A kernel that together fix this problem. As well as give you quandrant scores close to 2500! =D
Sorry to ask this, but I've been poking around the forums here and over @ the CM site itself and I have not been able to find the thread with this kernel. Could some kind soul take pity on me and point me in the right direction?
Many thanks!
Yeah the 4/13a kernel was one of the things I tried but forgot to mention. Its a little better but the issue remains. I'll wait til the next nightly thanks for the input guys.
And you can find the 4/13a download in the test build folder linked in dalingrin's oc kernel thread.

4/13A Test Kernel
Alsa Update - This fixes your issue, even with stock kernel. But works best with 4/13A for extra performance.
Yes I missed that. Thank you sooo much!
EDIT: That fixed it. Again thanks. I hate when I miss something small like that.

Thanks for the fix! Just applied it and 4 songs in....the "snap, crackle, pop" is gone. Happy camper here. Also thanks to the OP for bringing this up in such a thorough way, surprised I had not heard of anyone else having this issue.
Dsp manager
I've noticed for a while now since Nightly 27ish, maybe prior, that my DSP manager doesnt work correctly. To modify the settings through my headset, I actually have to modify the Phone Speaker settings.
Is this a known issue, or am I missing something?
Not sure this is the correct thread, but any input would be helpful.
Hitting this again on CM-7.1.0-stable
First off, this is by far the best and most thorough description of the music playback problem that I keep running into, so kudos and thanks to the OP!
But sadly, I upgraded to CM-7.1.0 stable and this is still happening. I see the mention of installing dalingrin's update-alsa-041411.zip, but I can't find that anywhere.
I'm also surprised that this problem is still present in CM 7.1.0 stable. Does anyone know what the new solution for this problem is?

[Q] Screen shaking

Hi All,
I am very new to galaxy tab.
I am running on official gingerbread, flashed following the guidelines on the site. Other than a checksum error it went smoothly and working just fine.
I have another problem though. When I hold it in portrait mode, trying to move up and down with my finger causes the screen to shake.
Somerimes more sonetines a little less but it is always there.
In landscaepe mode it almost does not exist, working smooth.
I tried doing a lot of search but could.not find anything on it.
unfortunately I did not pay attenrion if it was hapening on stock froyo, did not stay on that long enough.
Charging or not does not affect it.
Being suspicious about screen protector I rwmoved it but no change
Did anyone else experience anyrhing similar?
Thanks in advance for help.
Same problem here
Hi, I have the same problem here, I did woked on froyo for about a day or two, and the problem was not there, I upgraded to Overcome 2.0 and the problem is now there.
Similar to you, on landscape the problem is less evident, but still there.
In my case, on you-tube application, I don't have any shacking.
I hope someone finds a solution, problem seems to be software-based.
I just checked it, you are right, youtube does not present the same problem.
Lets hope for a solution from the experts.
Cheers
anyone?
this shaking is driving me nuts......the screen shakes so much when held down down that it pretty much renders google maps unuseable.
HELP PLEASE!!!
is it a screen sensitivity issue that we can tweak or something?
i've been googling for a month for answers now but no luck...
please please...
Similar topic in XDA
Hi guys, there is a similar topic here in XDA:
http://forum.xda-developers.com/showthread.php?p=14354988&posted=1#post14354988
I have the same problem in my Galaxy Tab, and I show in a page in fgfaria.com
I now suspect it may be a deffect in some specific feature in some library used by some apps and not used in other apps.
I installed Android SDK in my PC, and created an simple app following a tutorial, with a list of countries that can be scrolled up and down. In this very simple app, the problem doesn't happen, just like youtube.
I've found an app that could potentially solve the problem, but my GT is not rooted, and can't use it. It's called "ILITEK Touch Utility" and it's available for free in Android Market.
Let me know if it's useful for any of you.
Regards,
Fabio
My tab does exactly the same thing as per your weblink.
The app i have download but once i hit the calibrate button, I somehow get denied access.
Any way around it? This shaking is getting old......sigh
Software, not hardware
Hi all,
In addition to touch test apps and youtube app, there are some other apps that don't present the problem. One specific interesting case is the one of the HelloListView tutorial presented in Android Developers website.
I've followed the tutorial, and created this illustrative app that just creates a list and allows you to scroll up and down. This specific app doesn't present the problem we've been discussing. I've made it available for download as apk file in the end of that same testing page (fgfaria.com)
That application being so simple and not presenting the problem, and the other apps that also don't present it, makes me think that the problem may appear when some specific library gets included in an app. Possibly something related to hardware acceleration, for example (just guessing, no specific reasons to believe that).
If only we could isolate the cause of the problem, we could notify Google and/or Samsung and influence a new patch release.
This is as far as I have gone so far. Ideas, reactions?
Regards,
Fabio

Hi Chris, I believe the denied access is because the GT is not rooted. The app must need access to pretty low level adjustments, and only rooting the device would make that possible.
I have the same messages in my GT, but rooting is kind of my last option to solve this.
My current options are:
1) Wait for an official Gingerbread update
2) If that doesn't solve, I'll contact my factory warranty
3) If they deny this is a problem, or if they can't fix it, I'll try rooting and using this app
While the first option is not available, I'll continue my search for another fix.
Cheers,
Fabio

Another possible explanation for the problem not happening in the app from the tutorial is that libraries being used include some kind of filter not used in problematic apps...
mine shakes but not noticable,.. i didn't notice this on froyo
Hi,
Thank you all for responses. I have been searching too but did not find anything.
However I have a theory.
The screen shaking phenomenon does not happen (or unnoticably little) when you are on a dark screen. Web browser included.
Is this your observation too?
Cheers
mine do shake even if its dark, originally i found this "bug" couple of days ago, when im in bed late at night, i initially thought that the shaking was via my finger, and was surprised to see this post a while ago
Note: My tab is rooted because I'm currently running the Overcome 2.0 RC1 rom.
*major headache *
Fully agree! Mine shakes only in light background! Same problem, but in this case, it looks more like a hardware issue than software (intuitively, at least, hardware is more likely to be affected by screen luminosity than software). The solution though, could be a software filter of fast screen movements...
Anyone? There is a solution for Galaxy S (forum.xda-developers.com/showthread.php?t=844216&page=3#). There must be a solution for Galaxy Tab 7 too...
Hi everyone,
Is the same problem happening in the new 2.3.3 asia roms?
Do you have any experience?

[Q] Built a custom AOSP ROM, sound + video does not work

Hi All,
I wanted to learn how to build an AOSP ROM for my Droid Incredible (original version), and I was finally able to get a working build today (i've been at it for more than a month on and off when I have time).
I downloaded gingerbread-release and used the CM overlay to get the vendor-specific stuff. The proprietary files were pulled from my working OMGB phone (which I understand borrows a lot from cyanogen; well-- the kernel at least).
My problem is that (1) I can't get any audio to play, (2) any time I try to play a video (like Youtube) I get a force close, and (3) the camera wont work.
I'm pretty sure (3) is a totally different problem, as I've seen lots of ROMs where the camera won't work.
Does anyone have any point that I could start on this? I've posted my logcat here: pastebin.com/GPqpD8N3
(sorry-- I'm not allowed to post links yet.)
I googled it but I'm having trouble finding anything pertinent.
Thanks in advance for any assistance you anyone can provide!!
EDIT: By the way, since this post I have changed my setup. All of my proprietary modules are from the CM nightly build now, instead of having modules from OMGB and and overlay from CM. I did this to make it more consistent in case I run in to any more problems.
Sorry -- additional detail that I meant to add in the post (but it won't let me re-edit for 5 minutes):
The bottom of the log shows me trying to play a song in the music player. From what I can tell, /system/bin/mediaserver is crashing and performing a stack dump; however I don't know why or how I can fix it.
It will not play any ringtones either, but the DTMF tones *do* sound when you press on the digits, and the phone/speakerphone work fine as well.
I just figured it out myself... in the logcat there is the line:
frameworks/base/media/libstagefright/omx/OMXMaster.cpp:90 err != OMX_ErrorNoMore
if you go to that file, in line 90:
CHECK_EQ(err, OMX_ErrorNoMore);
I just commented it out and sound works fine.
Now if I can get the camera working... any ideas?
Hmm I know the bugglas beast nightly's had the camera issue.
Sent from my ADR6300 using XDA App
Thanks, @Kiboe for the reply. I found the fix last night (right after I posted ) on xda-developers through Google Groups.
I implemented @dferreira's suggestion, and it compiled just fine. Now I have a working camera, but video still isn't working. (Also accelerometer isn't working, but I believe I have already found the answer for that).

CM9 Nova HD Plus v1.1 discussion

Hi All,
Since i am not allowed to post directly to the original thread to the great CM9 ROM from hei1125 -- Nova HD Plus v1.1,, http://forum.xda-developers.com/showthread.php?t=1508492
I have to ask here who had this ROM and discuss our experiences.
So far i got 2 issues:
- the voice call is very light said the call receiver, could anyone confirm? is there a way to increase the volumn?
- Google map zoom with two fingers is pretty bad, not smooth as it used to be on CM7
Thank you.

For calling and internet related issues, I would always check baseband and RIL first. I'm using the 750 baseband (as suggested by the developer) and got the matching RIL with GetRIL from the market. I have no issues with volume. I'm not quite sure whether I can reproduce your Gmap zoom issue, but perhaps this is because we are still lacking some graphic drivers from nvidia. Just my 2ct...

Yes I did had a lot of troubles with baseband and RIL,,, i tried GetRIL for help with my the latest temsak Kang, where i had problem that sometimes the mobile network is disconnected while screen off.
I felt this new ICS ROM is much better related to connection, only the volumn is too low.
I installed RC3-6 and really enjoyed the ICS experience. The ROM is smooth and stable as advertised.
However some key features are not working i.e. camera video
and some minor things like no support for wired headset button which ruins my usual music listening routine.
I tried this with Ironkernel but couldnt get it working due to the low memory error.
Wiped and installed again without the kernel and this time it worked great, nice ROM. Only problem is I need TUN support to get my vpn working and the included CM9 kernel doesnt seem to have this enabled.
Any other kernels i can try with CM9?

as far as i read from the forum, Ironkenel is great for performance however many other problems like faster battery drain,, so i would stick to the standard kernel and wait for the features to be implemented... at the end, the kernel is still in a relatively early stage and i am happy with the stability we could get so far.

In german forum android-hilfe.de
I offer a little Mod for CM9, it changes the color of pressed buttons from orange to ICS/CM9 blue,and the battery icons.
Since I use your rom, the mod works in your rom too So the question is, is there a difference between framework-res.apk and systemui.apk in RC4 and RC5
I have gone back to cm7 as I need certain features for daily driving but the Nova rom has me itching for LG to release their update ASAP and look forward to all the custom roms to follow. XDA developers rock!
