From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: Updating to the kernel-2.4.20-13.8.athlon has broken the i810 sound on an ECS K7S5A motherboard (Athlon XP, Sis7012 sound). Dropping back to the 2.4.18-27.8.0 kernel allows sound to play normally. dmesg reports the following: i810: SiS 7012 found at IO 0xd800 and 0xdc00, MEM 0x0000 and 0x0000, IRQ 10 i810_audio: Audio Controller supports 2 channels. i810_audio: Defaulting to base 2 channel mode. i810_audio: Resetting connection 0 ac97_codec: AC97 codec, id: CMI65 (CMedia) AC97 codec does not have proper volume support. i810_audio: only 48Khz playback available. i810_audio: AC'97 codec 0 Unable to map surround DAC's (or DAC's not present), total channels = 2 /etc/modules.conf shows: alias sound-slot-0 i810_audio post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : Version-Release number of selected component (if applicable): kernel-2.4.20-13.8.athlon How reproducible: Always Steps to Reproduce: 1. Install kernel update to 2.4.20-13.8.athlon 2. Reboot 3. Attempt to play sound through xmms, mpg123, etc.. Actual Results: No sound... It should be noted that the player applications (including ALSA, esound, OSS) think that the device is functioning normally. Visualization plugins will function and there are no errors. However, the speakers are silent. When adjusting the volume sliders in Aumix or Volume Control I can hear a clicking sound but nothing else. Expected Results: Blessed sounds of a Mozart piano concerto should have filled the room. Additional info: This also fails on RH9 running the latest kernel based on the 2.4.20 series.
I've fixed this problem in the -ac tree and set Marcelo a fix for it.

Sound is again working in kernel-2.4.20-19.8. Thanks!
