Description Kwan Lowe 2003-05-23 20:02:29 EDT
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):

How reproducible:

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.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
