From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: There are two problems. On boot both snd-atiixp-modem and snd-atiixp load. It seems that snd-atiixp-modem conflicts with snd-attixp as it shows as being used more (vis lsmod) than snd-atiixp. Additionally, alsamixer complains that no sound elems are available. No errors are ever reported when sending audio to the driver but no sound comes out. By removing snd-atiixp-modem from loading automatically on boot (so that only snd-atiixp loads) snd-atiixp complains about "codec acquire timeout" errors in the logs. In older kernels I would get this error but could fix it via pci=noacpi in the grub loader. It wouldn't work 100% of the time (never on first boot.) but always on the second boot. This did not solve the problem on FC3. So I downloaded the vanilla 2.6.9 kernel from ftp.kernel.org, built and installed it. Sound works, everything works on the vanilla kernel. But I really want to use the fedora kernel. My System: Toshiba A70 (with ATI IXP 150) Version-Release number of selected component (if applicable): kernel-2.6.9-1.678_FC3 How reproducible: Always Steps to Reproduce: 1. Boot Computer 2. Select 2.6.9-1.678_FC3 Uniprocessor Kernel in grub 3. Try to use sound Actual Results: No sound comes out. If you keep snd-atiixp-modem from being loaded you get a lot of "codec acquire timeout" errors. Expected Results: Those errors should not appear. Mixer Should Work. Sound should play.

I did some more testing. I was able to get the Fedora Core 3 Kernel to work better (still not 100%) by not compiling alsa from the kernel sources but replacing it with alsa 1.0.7. Still, first boot does not work, but it works on subsequent boots. Additionally, unlike the vanilla 2.6.9 kernel, fc3 kernel with alsa 1.0.7 does not need pci=noacpi for it to work.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you.
