Since 3 or more weeks, I have no more sound, there is no error in dmesg after boot of the system, all the modules for my 2 sound cards seems to be there. The problem appears since the last update of the portage package,even if I don't think it is the source of the problem. My version of the portage package is 2.1-r1. Alsa is compiled via alsa-driver. The version of the kernel source is gentoo-sources-2.6.16-r13 and alsa-driver is alsa-driver-1.0.11. The only strange thing that i have seen is that the file /proc/asound/card0/oss_mixer contains the following: VOLUME "Master" 0 BASS "" 0 TREBLE "" 0 SYNTH "Synth" 0 PCM "PCM" 0 SPEAKER "PC Speaker" 0 LINE "Line" 0 MIC "Mic" 0 CD "CD" 0 IMIX "" 0 ALTPCM "" 0 RECLEV "" 0 IGAIN "" 0 OGAIN "" 0 LINE1 "Aux" 0 LINE2 "" 0 LINE3 "" 0 DIGITAL1 "" 0 DIGITAL2 "" 0 DIGITAL3 "" 0 PHONEIN "Phone" 0 PHONEOUT "Phone" 0 VIDEO "" 0 RADIO "" 0 MONITOR "" 0 And it is the same for card1. I have tried to modify /proc/asound/card0/oss_mixer with emacs, but the editor complains because the file was modified when I try to actually modify it or save my modification. I have search on the forum and even post in it (http://forums.gentoo.org/viewtopic.php?p=3441521#3441521, my nickname is RealNoob), but without any luck.

Sorry, my fault, I have forgot to precise that alsamixer reports that all channels are unmuted for the 2 sound cards. What was my comment is that after checking that everything was unmuted, I have tried to modify this file (/proc/asound/card0/oss_mixer) manually to check if that make any difference before continuing my investigations. But, as said earlier, without any luck. To give you even more details that I should have joined with the initial comments, my two sound cards are: - Soundblaster 64 PCI, its module is snd-ens1371 and alsamixer show the chip as TriTech TR28602. - C-Media PCI CMI8738-MC6, its module is snd-cmipci and alsamixer show the chip as CMEDIA PCI. Hope this time I have forgot no information :(.
Please, read the following howto, Gentoo bugzilla is really not a support forum. If you need support, use forums.gentoo.org or #gentoo on IRC. http://www.gentoo.org/doc/en/alsa-guide.xml rm -f /etc/asound.state, run alsamixer, set up volume for your cards, run /etc/init.d/alsasound save. For starters, I'd suggest to disable the other card and use just one, can play with that once the first one works.
