Description of problem:

2.6.15-1.1831_FC4 #1 Tue Feb 7 13:37:42 EST 2006 i686 i686 i386 GNU/Linux
I have been running 2.6.14-1.1656_FC4, 2.6.14-1.1653_FC4, and 2.6.11-1.1369_FC4

Running sound card detection looks like it works, but still no sound.
However, when you plug and unplug the power plug the laptop "beeps".
How reproducible: Constant ...

2. Play a sound file ... (works)
3. Do a Yum -y update to the latest and greatest
4. Try to play a sound file ... (fails!)

Could you enable dnix/dsnoop in system-config-soundcard and check it again? Or
you can check the "External amplifier" switch in alsamixer (a command line

I've attached 4 log files (probably did it wrong, trying to work out BugZilla!).
I've tried all the combinations with dnix/dsnoop ticked and not ticked, for the
two sound card entries that appear.
I've also tried the external amplifier settings on alsamixer.
Still not a peep out of it!
You can check the latest drivers, how-to is here:
btw. you can check the old-driver, too. It was 1.0.9 and you can find it on
http://www.alsa-project.org. Instalation steps are the same as above...
I've tried to build the 1.0.9 driver, but I get a great list of errors. the
1.0.10 driver builds and installs, just does not work!!!
I've played with it, but I'm not getting anywhere, so I've kinda decided to hang
out for FC5 next week and do a full install.
On my how-to page are new packages for ALSA 1.0.11rc4, you can check it...
