Comment 2 for bug 192382

I can confirm this after an upgrade from gutsy to hardy. My PC is a toshiba satellite A100-237. Sound worked perfectly in Gutsy . Furthermore there are no more inputs (no microphone), only outputs. Pulseaudio seems to be functioning properly, with proper level meters on playback, however no sound can be heard. KMix does not work. Media players (VLC , mplayer) are working as far as they are set to use the hardware device. Amarok with xine is unable to initialise audio devices. Alsamixer and amixer does not work:
kane@kane-laptop:~/muzik/testfiles$ alsamixer -c 0
alsamixer: function snd_mixer_load failed: No such file or directory

kane@kane-laptop:~/muzik/testfiles$ amixer -c 0
amixer: Mixer hw:0 load error: No such file or directory

and my specs:
