[Bug 269294] Re: Acer Aspire 5520 cannot record sound with HDA-Intel NVidia Codec ALC268

[Andres Mujica]

Hi, thanks for testing..

the problem you're facing is caused by applications using the sound. So
we need to kill those while on the LiveCD in order to test.

1.- be sure none sound application is running
2.- kill pulse audio. From a terminal sudo  killall -9 pulseaudio
3.- kill mixer applet:

this would need some commands but is doable.
 - sudo ps ax | grep mixer
 - you'll get a warning about reloading mixer applet.. don't close the window until you remove the module
 
4.- sudo rmmod -r snd_hda_intel
5.- made the changes to alsa-base
6.- sudo modprobe snd_hda_intel
7.- reload volume applet

well.. it seems hard i know.. the other option is to install it directly
at the machine and test more easily (reboots between changes).

Hope this helps and let us find the issue.

regards,
