Re: Sound problem with P7H55 MoBo Intel IbexPeak HDMI aplay versus alsamixer -ALC892
Hi Oleg, Thank you for a tips I tried to follow t your tips with no result. First, kernel documentation HD-AUDIO-models.txt is not up to date because kernel 2.6.36 knows this ALC892 model. (/sound/pci/hda/patch_realtek.c) But all my attempts to select model as modprobe option for snd_hda_intel fiailed, and the delegating to bios did not help. So I do not have sound in 2.6.36 and even in 2.6.37-rc6 - no sound at ALL !

This probably means that what follows is not the solution, but if you have no other ideas you might want to try your options. Check your /etc/modprobe.d/alsa-base.conf (or whatever the Ubuntu equivalent is) against "lspci | grep Audio" to see if the model specified looks right. If you decide to play with the model then you may try the following: 1) choose the default "auto" model, in this case the kernel relies on the BIOS, and this means that the sound device should be enabled in the BIOS - check that. I did it 2) disable the sound card in the BIOS, boot, choose this or that model that looks relevant from the HD-Audio-Models.txt list, and reload the module/modules. I tried, but no matter what I wrote in alsa-base.conf I got no sound Just some random ideas... -- Oleg Goldshmidt | o...@goldshmidt.org ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
