I have a system with daily rawhide updates except the kernel. When I use the old 2.6.15.3 based kernel the sound works fine. If I update to recent kernels there is no sound, just silent, no error messages or anything and alsamixer shows sounds all turned on. This is also reported by other people at alsa and kernel-list but none of the suggestions works. I have also rebuilt the kernel with git.alsa patch to no avail. I am beginning to wonder if this has to do with alsa-lib being at rc2 rather than rc3 (git.alsa) but can't tell. By the way this is a dual-core x86_64 em64t system. Thanks
The only advice that I can give you is to use a driver which works for you. Some how-to is here: http://people.redhat.com/stransky/alsa
I don't think that is an option if I want to use FC5. The problem is in the 2.6.16 kernel modules so far and if it does not get fixed there will be a lot of users asking the same question baout hda-intel. I have been communicating with some of the alsa developers but so far no results for me. I did file a bug report under Fedora kernel as well. Is your responsibility limited to alsa-lib and alsa-util packages only? You have a redhat e-mail so I presumed that you work there.
Yes, my responsibilities are alsa-lib and alsa-utils, I'm not a kernel-hacker...
