Description Keith Miller 2006-02-22 04:37:24 UTC
Description of problem:

Sound on IBM T42p Laptop stopped working after kernel upgrade to:
 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
with no problems. After the "yum update" to the 2.6.15-1 kernel I don't get any

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 ...

Steps to Reproduce:
1. Install FC4 on an IBM T42p 
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!)

Attached is the scsound.log from the sound card detect

Comment 2 Martin Stransky 2006-02-23 13:05:47 UTC
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

Hi Martin,

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:

Comment 9 Martin Stransky 2006-02-27 14:39:19 UTC
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...

Comment 10 Keith Miller 2006-03-16 07:23:45 UTC

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.



Comment 11 Martin Stransky 2006-03-30 09:18:57 UTC
On my how-to page are new packages for ALSA 1.0.11rc4, you can check it...
