Microphone issues in android-x86 7.1!

[techd...@gmail.com]

I just installed android-x86 7.1 and it seems that the microphone is not working. I googled and yet found no solution!

There isn't an issue with my ports or the microphone itself, because I verified.

I hope someone can help me out with this!

How?

Does sound output work?

> I hope someone can help me out with this!

Tell us what hardware you have, what the sound chip is, whether it works with
Linux on the same machine - tell us as much as you can to help us understand
specifically what problem you have and what system you are having it with.

Otherwise all you're saying is "my microphone doesn't work" and all we can say
is "oh".

Thanks for answering!

I made a partition on my Desktop PC and installed android-x86 7.1

I made the following searches

"Microphone not working in android-x86"

"Microphone not working in android-x86 7.1"

The solutions there didn't work for me. Also the questions had been asked for Android-x86 4.4.

> Does sound output work?

Sound output works very well. I am having issues with the microphone.

I have a 64-bit machine, Intel(R) Pentium(R) Dual CPU E2220 @ 2.40GHz. As for the sound chip, I don't know what it is.

I have a Ubuntu and windows partition on the same machine and the microphone works fine. Only the microphone doesn't work with android-x86 7.1. 

I think I have specified the bits of detail. Now maybe someone can help me out.

Can anyone kind of help me out! It is an emergency!

Have you checked your catlog from boot to see which device is enabled on the boot process for audio input. I had some troubles with my audio output, because wrong device was the primary for output. You can search the forum about audio output issues that have been diacussed by me and other users and try those tricks to see what can be done to the audio input.

[Rob Cosentino]

Only the "Front" microphone input is active. And the "Rear" output is active for speakers/phones.

I have not yet tested the 1455 Positive Mobile notebook microphone in some messenger application with audio and video. Starting tomorrow, Monday, when my colleagues are at work I will ask them to take the test you mentioned.

It would be of great help if you could post the steps you took to solve the issue.

[techd...@gmail.com]

Did you work on it? Any observations?

[techd...@gmail.com]

I didn't get you! my PC has only 1 port for the microphone.!

In that thread Chih-Wei Huang walks me trough how to read the catlog to see which audio device is selected by the operating system as the main output device. You might be able to use those commands to see which card your system picks for input. Then you could add the rm (remove) commad to init.sh for removing the wrong card and the use the killall audioserver to force the system to choose the other card. But ofcourse this works only, if your problem is because wrong device gets chosen for input.

[youling 257]

you need check alsa_amixer -c0 or c1 state，

for example，

alsa_amixer -c0 set 'Front Mic' on

alsa_amixer -c0 set 'Front Mic' 100

alsa_amixer -c0 set 'Front Mic Boost' 1

alsa_amixer -c0 set 'Rear Mic' on

alsa_amixer -c0 set 'Rear Mic' 100%

alsa_amixer -c0 set 'Rear Mic Boost' 1

alsa_amixer -c0 set 'Line' on

alsa_amixer -c0 set 'Line' 100%

alsa_amixer -c0 set 'Line Boost' 1

alsa_amixer -c0 set 'Input Source',0 'Rear Mic'

[techd...@gmail.com]

I tried reading the whole post and nothing could help out!

Have you checked your bootlogs what device the android chooses for input? What happen when you use the alsa_amixer commands?

Not a lot can be done by anyone else, if you don't provide any meaningful debug info like parts of the bootlog or errors from commands. You say, you have read the thread, but have you tested any of the command in this thread or the other one. If you have, can you provide any info on what output (logs, errors, info) you get from them. There are actually many threads in this forum covering audio output and I think also input. Have you read them and tested the suggestion given in them?

I don't mean this post in any negative sense, I just wan't to say that it is easier to get help, if you can provide more info on your system and the things you have tried to fix the errors or analyze them. Hope you get some usefull advice.

[techd...@gmail.com]

I am really sorry for the inconvenience that I am causing you. I am a total newbie. How do I check the bootlog? And specifically, how do I check for the audio input device in the bootlog?

I would really appreciate if someone could guide me through the commands and everything.

All that I know about the issue is this : my mic is not working when I plug it onto the android machine no matter what. I am sure that the port or mic is not bad since the mic is working when I boot into ubuntu on the same machine.

If you want me to post any result from any command so that you could debug the issue, I am glad to do so. Sorry for being such a stupid noob. Forgive me. I am ready and willing to learn.

Please help me!

I tried this but it didn't work!

[Tech Desk]

I did some testing on my end. I installed the same version of android in my laptop and the microphone was surprisingly working. I also installed the same ISO on my other computer that has front microphone ports and it did work.

The one I have trouble is with the computer that has only rear ports.

I think that the issue here is android not recognizing the microphone rear port. Can anyone help me make android recognize my microphone?

I think I should change some configuration file but not sure exactly which.

There seems to be no issue with my sound card adapter. It looks like android-x86 is not recognizing the microphone for some reason. I hope some of the geniuses in this group will help me fix my issue. It's been long since I started this thread and my issue isn't yet solved. Still waiting..............

Have you ever provided any useful debugging info?
dmesg and logcat are essential.

You even didn't say what device you are testing exactly.

I am so sorry for not providing these information from the beginning.

Here is the output of "dmesg | grep audio" : https://ufile.io/uchz7
Here is the output of "logcat | grep audio" : https://ufile.io/ltwr7

If you want the whole output, tell me and I am willing to provide.

[Chih-Wei Huang]

None of these contain useful info.

Please provide full log from booting
and using the microphone.

What's the output of the commands?

cat /proc/asound/cards
ls -l /dev/snd
lsmod

Besides, please avoid using a hosting
with so many ads. It's annoying.
Google Drive is good enough.

[Tech Desk]

Ok! I booted up the system and tried to record an audio.

I have created a Google Drive folder and put all the command outputs that you wanted in separate files. :

Looks like you have two input nodes:

04-26 12:27:36.574 1098 3623 D audio_hw_primary: found audio in at

04-26 12:27:36.574 1098 3623 I audio_hw_primary: choose pcmC0D0c for 0

The audio HAL chose the first one, however,
maybe the second one is correct for you.

Try this command:

setprop hal.audio.in pcmC0D2c
killall audioserver

Then test microphone again.
If that works, you can add the setprop command
to /etc/init.sh.

[Tech Desk]

I tried the commands you specified. Unfortunately, it didn't work out for me.

Before trying your commands, the recorded audio playback had some frequency sound. After trying your commands the audio playback is completely null. I don't know why though.  

[Tech Desk]

Any hope for me?

So pcmC0D0c is just right.
You don't need these commands.

Then I guess your microphone was broken,
or it has to be configured by some special parameters.

To try that, use a normal Linux distribution (ubuntu/fedora/...)
to test the microphone, adjust it by amixer to get
an acceptable quality, then save the astate and
copy it to android-x86. If you even can't get
an acceptable quality in this way,
I think your microphone was broken.

I am pretty sure that my ports and mic is fine since it works perfectly on Ubuntu. I would like to know how to save the astate on linux and copy it to android-x86. (Google search didn't get me any results). Can you please give me the required steps to copy the astate from linux to android-x86? I would appreciate that.
