Description Todd Warner 2007-01-15 00:25:45 EST

Description of problem:
I installed FC6, sound would not work.


Version-Release number of selected component (if applicable):
alsa-utils-1.0.14-0.2.rc1.fc7
alsa-lib-devel-1.0.14-0.1.rc1.fc7
alsa-lib-1.0.14-0.1.rc1.fc7

Note: these are the devel alsa's that I updated in attempt to solve the problem.
I suspect the problem and "fix" will replicate with the shipping alsa.

How reproducible:
Easily, given you have the hardware.

Steps to Reproduce:
1. Acquire Intel Corporation 82801G (ICH7 Family) High Definition Audio
Controller - my T60 laptop comes with it.
2. Install fc6 with all updates.
3. Attempt to config sound.
4. Won't work.
  
Actual results:
No sound.

Expected results:
Sound.

Additional info:
I "fixed it" by adding two lines to rc.local:
modprobe -r snd_hda_intel
modprobe snd_hda_intel

This solution was discover after a prolonged time of googling for a solution.

Comment 1 Martin Stransky 2007-01-15 05:58:32 EST

Please check the latest ALSA drivers, your soundcard should work out of the box
with them. How-to is here: http://people.redhat.com/stransky/alsa

Comment 2 Martin Stransky 2007-04-10 08:48:32 EDT

Please attach /root/scsconfig.log (can be created by system-config-soundcard)

Comment 4 Martin Stransky 2007-04-10 10:30:22 EDT

Do you use digital or analog output?

Comment 5 Todd Warner 2007-04-10 11:00:40 EDT

Digital did not work, so I am using analog.

Comment 6 Martin Stransky 2007-04-10 11:37:21 EDT

okay, so you should have these lines in your /etc/asound.conf:

defaults.pcm.card 0
defaults.pcm.device 0
defaults.ctl.card 0

does the sound work with them after boot?

Comment 7 Todd Warner 2007-08-29 07:41:45 EDT

Sorry, that this took so long to respond to.

My /etc/asound.conf was completely commented out. I set them to what you
suggeste. Doesn't work, unless I did what I described.

New issue: With the latest kernel, kernel-2.6.22.2-42.fc6, the sound broke
immediately, even with my changes. So far the only fix I can find is to init 1,
manually monkey with the modprobes and then init 5 again. Ugh!

What's going on with alsa?

Comment 8 Todd Warner 2007-09-05 12:02:55 EDT

Fixed.

I enabled the internal modem in the bios and the sound started to work. I even
removed my hack.

May want to document this.

Yeah, that's a known issue on T60 :-(
