Folks,
I am experiencing low mic volume output after installing cm-10.1-20130411-EXPERIMENTAL-p5110-M3 on a Samsung Galaxy Tab p5113. The application we are testing is video and in this case the mic volume is really low. This is a tablet to tablet skype like video session. Here the other end perceived very low Audio coming from the Tab with the CM-10.1-20130411-EXPERIMENTAL-p5110-M3. Stock ROM mic levels were fine. I read through a bunch of the forum and saw some folks noting this issue with other older CM builds.
I was able to install the Alpha Widget app and it has a mic gain control function. Does anyone know what this gain control actually manipulates within the Android OS/Kernel? It would be great to manually manipulate this mic gain at OS / CLI level.
Is there any file/value that I can modify at the OS level to manipulate the Volume output of the Mic?
Any other ROM's that you might recommend that handle mic volume/Audio/Video better than the ROM mentioned above?
Thanks in advance.

Hi, I recently installed CM10 v.0.9.2 on my Lenovo Thinkpad Tablet. Everything seems to work well, however the audio seems very high-pitched (not enough bass) and the maximum volume was not as high as I would like it to be. Two questions:
1. How does this mod handle audio (what audio drivers are used, ALSA, or other)?
2. Is ALSA installed? I noticed there was a directory /system/usr/share/alsa containing a configuration file, alsa.conf. If not, what is the best way to install it?
Thanks!
I have also noticed that the audio volume attenuates significantly when 'maximum' is reached using the volume button. However, if I back it off or make adjustments via the software settings, then it appears to improve (although not quite as well as I hope).
I would also appreciate some info and fix...
Audio drivers appear to be nvmm, Nvidia proprietary drivers.
Hi
Hope I'm posting in the right forum but since this is related to hardware I'm posting it here.
For most musicians this is a big issue.

As I understand it there is no way of lowering the input gain on android which makes recording sound, say at a concert or in the rehearsal room, impossible because of the distortion created by the high input gain on the mic of android phones.
I can't believe that this hasn't been fixed but apparently it hasn't. I think we seriously need this fixed and it should be possible on a custom ROM shouldn't it? I'm not an app developer and I don't know how to code but it should be possible right?
If anyone manages to to fix this I'm sure there'd be a lot of people who be very grateful.
An interesting question.
I'm not sure how many Android devices use ALSA as the underlying layer.
ALSA supports controls.
I haven't looked into my Kyocera Rise.
On my Barnes & Noble Nook Touch I use a Lexicon Alpha 24 bit interface and a Shure SM58 through USB OTG and ALSA.
I use a custom recorder app (since Android doesn't support 24 bit).
It makes dandy recordings.
Thanks for the answer but what I want to be able to do is to record directly to my phone in a high volume environment without the use of an external soundcard or even an external mic. I know that the sound quality wouldn't be very good but it would suffice in the rehearsal room or at a concert for personal use.
I updated to the newest build, however, my bluetooth volume is still linked to the system volume and causes all sorts of issues. I'm using beats powerbeats 2 wireless. It ends up killing the sound quality when I run music through viperaudio. Fortunately, I found a slight work around by reducing the output gain to -.8 It's good, but not what it's supposed to do. Does anyone have a fix or am I missing something. I'm also running the newest test build on DU. Thanks in advance for any help.
When connected to BT it will use the system volume. That is the way it is meant to work as it over rides the default.
Hi all,
I recently installed LOS and I was satisfied with it except for the low volume of the mic with some apps.
Phone calls with the device mic were fine, but using a headphone with mic resulted in very low sound of my voice on the other hand (tried Whatsapp, Signal and Skype).
For voice recording both mics were low.
With the stock rom the volume was fine.
After reading some sources I found the file /system/vendor/etc/mixer_paths_0.xml and started changing some values, but my first tentatives did not solve the problem.
Then I decided that to experiment quickly with different settings it was impossible to modify that file manually, and I have therefore written some simple scripts to automate the process.
The repository is here:
GitHub - sbocconi/LOS_SM_A510F: Directory to manipulate mic settings for Samsung A5 running LineageOS
Directory to manipulate mic settings for Samsung A5 running LineageOS - GitHub - sbocconi/LOS_SM_A510F: Directory to manipulate mic settings for Samsung A5 running LineageOS
github.com
Maybe it can be useful for somebody else, and maybe more people can experiment with the values to get an optimal result and share it.
I have now managed to increase the volume in my tests so far with Whatsapp, Skype, voice and video recording, but I guess there can be some fine tuning of the values to for example have little echo while still having a decent volume.
Thanks for sharing
Hello guys and gals
I've been trying a lot of custom ROMs for our beloved 9T, and as is usual they all have their little bugs and quirks, some more some less.
However, one problem I noticed affects ALL custom roms for our device (well, the ones I tried at least) is that the microphone audio from any wired (3.5mm jack) headset has a VERY LOW VOLUME. Whenever I record a voice note in Whatsapp or any other app, or when I have a meeting with Google Meet, or even just recording my voice with a Voice Recorder app, it's extremely quiet, unless I talk right into the mic.
This was not the case on MIUI, so it's clearly a custom ROM issue. I wanted to know a couple of things:
1) I'm not crazy right, external mics DO have low volume on custom ROMs, yes? Or is this some issue specific to my device?
2) Any workarounds/solutions you can suggest?
By scouring the forums and searching on google, I think the problem is some misconfiguration in the /vendor/etc/mixer_paths_idp.xml file, however I have no clue which values to modify, since from what I read the values you should change are different depending on the device.
Any help or suggestion on this matter would be appreciated.
