Description Mathias Homann 2006-01-17 16:08:11 UTC

here's the output of lspci|grep -i audio:
00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)

when I use kmix to change the volume of the master channel, nothing happens. i have to change the exact subchannel.

Comment 1 Takashi Iwai 2006-01-19 14:14:17 UTC

Check whether "Headphone" control influences the volume.  If yes, add ac97_quirk=hp_only to the options of snd-intel8x0 in /etc/modprobe.d/sound file and restart the alsasound.  Then show "lspci -nv" output to enable this as default in future.

If the headphone doesn't affect the volume, it might be that your chip has really no volume control on hardware.  Please attach /proc/asound/card0/codec97#0/* files, and /etc/asound.state file for debugging.

the ac97_quirk=hp_only did it;
here's the output of lspci -nv.

OK, then this was already fixed in 10.1 kernel.  Thanks.
