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, -- Acer Aspire 5520 cannot record sound with HDA-Intel NVidia Codec ALC268 https://bugs.launchpad.net/bugs/269294 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
