[SOLVED!] Saving, keeping Alsamixer Mic Boost level

[sebastjava]

I have a little Asus netbook. When i first tried the microphone, there was just noise. I found i just have to turn Alsamixer Mic Boost level to zero to fix that issue. For those who did not know, Alsamixer is a kind of graphical interface that can be opened by typing "alsamixer" in a terminal.

But Alsamixer forgets my setting each time i restart the computer.

So here is my question: is there a way to permanently store Mic Boost level in Alsamixer, so it remains set to zero after restarting?

You could run a script on boot that contains the command to set your level to zero.

Thanks, i will probably try such a script. I am closing this topic because i have to think and search more first. I tried sudo alsactl store : it does restore the settings from one session to another, but not after a restart. I suspect Pulse Audio is also storing/restoring some values so i might have to control both Alsamixer and Pulse Audio...

I probably could have inserted this amixer sset 'Mic Boost' 0 in the system start. But i preferred to edit the source of the problem. It works! Now the Internal Microphone sounds fine on my little Asus EeePC X101ch. Here is what i did:

Code: Select all

# Disable auto adjusting of gain on mic:
# Edit as root: /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf
# Edit as root: /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf
# Under "[Element Internal Mic Boost]" set "volume"  to "zero".
# Under "[Element Int Mic Boost]" set "volume"  to "zero".
# Under "[Element Mic Boost]" set "volume"  to "zero".
