Re: [FIXED] Mic not working

The mic device is there, how do you surmise "not working", what are you using to test? What does

arecord -Dhw:1 test.wav

result in?

Re: [FIXED] Mic not working

 arecord -Dhw:1 test.wav
Warning: Some sources (like microphones) may produce inaudible results
         with 8-bit sampling. Use '-f' argument to increase resolution
         e.g. '-f S16_LE'.
arecord: set_params:1387: Sample format non available
Available formats:
- S16_LE
- S32_LE




 arecord -Dhw:1 test.wav -f S16_LE
arecord: set_params:1398: Channels count non available

that didnt work i tried

 arecord -d 5 -f cd -t wav test.wav 

but the sound file was empty

Re: [FIXED] Mic not working

cd format will try stereo that can often not work, what about

arecord -Dhw:1 test.wav -f S16_LE -c 1

? What do you get from

amixer -c1

?

Re: [FIXED] Mic not working

mhm, we see that your mic is muted, what happens if you try your working command that produced an empty file but beforehand do a:

amixer -c1 set 'Internal Mic',0 unmute
amixer -c1 set 'Mic',0 100% 100% unmute
 arecord -d 5 -f cd -t wav test.wav

Re: [FIXED] Mic not working

amixer -c1 set 'Internal Mic',0 unmute

amixer: Invalid command!

arecord -d 5 -f cd -t wav test.wav

still a noiseless file...

Re: [FIXED] Mic not working

Sorry this one fell of the radar a bit.

This setup in general reads weird but maybe try

amixer -c1 set 'Internal Mic',0 capture unmute cap
amixer -c1 set 'Mic',0 capture 100%  capture 100%  capture unmute playback mute

I'm not sure why a mic can be regarded as a playback device, potentially for loopbacks but it's not what you want, FWIW you didn't set a kernel param for dmic_detect=0 or dspcfg=1 or so?

I'm going to pretend I didn't read that, but I suggest you refrain from throwing stuff like that around depending on who's on the receiving end.

very sorry for that offensive term. my friend wrote that as a troll i tried to delete it but i couldn't find a button

on the code side i didnt touch anything on system by hand and i still get a quiet file. but if it helps, on Unsigned 8 bit, Rate 8000 Hz, Mono its gets a pop effect(like a corrupted noise) last second no matter the length of recording

and how can i check the kernel params?

Re: [FIXED] Mic not working

I tested my mic with an other linux distro(fedora on the usb) and the mic wasnt working there either.. i guess my mic just randomly went down thanks for the help btw!
