I'm having some problems with audio now that I've started using the 2.6.9 kernel that I built. Audio did work with the 2.6.8-3-amd64-k8-smp kernel that came with the install image.
lspci shows the audio controller: rosebud:~# lspci | grep -i audio 0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) The right drivers seem to be loaded: rosebud:~# lsmod | grep -i audio i810_audio 40344 0 ac97_codec 21016 1 i810_audio soundcore 12256 2 i810_audio,snd However no sound comes out when I play an audio file. Looking at dmesg output, it seems the controller shows up, but only on one line: rosebud:~# dmesg | grep -i audio Intel 810 + AC97 Audio, version 1.01, 18:06:18 Nov 5 2004 As opposed to several lines when looking at the dmesg output for the previous kernel: rosebud:/var/tmp# grep -i audio dmesg.2.6.8-3-amd64-k8-smp Intel 810 + AC97 Audio, version 1.01, 00:32:26 Aug 30 2004 i810_audio: Primary codec has ID 0 i810_audio: Audio Controller supports 6 channels. i810_audio: Defaulting to base 2 channel mode. i810_audio: Resetting connection 0 i810_audio: Connection 0 with codec id 0 ac97_codec: AC97 Audio codec, id: ADS116 (Unknown) i810_audio: AC'97 codec 0 supports AMAP, total channels = 2 i810_audio: setting clocking to 48607 Any ideas what the problem might be or how I can debug this?
