Description Jeff 2005-01-14 15:52:01 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3)

Description of problem:
After upgrading to kernel-2.6.10-1.8_FC2, sound no longer works.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Upgrade to kernel-2.6.10-1.8_FC2 via yum
2. Reboot
3. Try to play audio using 'play' or 'xmms'

Actual Results:  Silence

Expected Results:  Rock'n'roll

Additional info:

I've seen this problem in two FC2 systems, here is the sound card info
for both systems from lspci:

System 1 (Dell Dimension 8200)
02:0a.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24
[CrystalClear SoundFusion Audio Accelerator] (rev 01)

System 2 (Tyan Tiger 133 running SMP kernel)
00:13.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1
(rev 07)

The work-around is to just boot an older kernel.

Comment 1 Jeff 2005-01-15 06:24:33 UTC
Oops my bad, the Creative Labs SB Live! EMU10k1 is working. I'll try
to get my hands on another Cirrus system for further testing.

Comment 2 Kevin Gottsman 2005-01-15 06:42:01 UTC
I can reproduce the problem on my FC3 system as well.

Bad kernels:

Working kernels:

Hardware Info:
00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)

Comment 3 Kevin Gottsman 2005-01-15 22:19:31 UTC
I found another user at Fedoraforum.org with the same problem. Both of
us have the AC '97 audio controller and both seem to have problems
with snd_intel8x0 and snd_intel8x0m module. Audio seems to be working
fine with no errors but no real sound output.

The solution to my problem was to mute the headphone jack sensor with
alsamixer. His was to mute the external amplifier.

Temporary Fedoraforum.org link (I guess they are moving servers today) : 

Comment 4 Miloš Komarčević 2005-01-17 10:19:57 UTC
This is probably a dupe?

Cirrus Logic issue is bug #144767

snd_intel8x0 issue seems to be unrelated bug #144742

Comment 5 Pontus Enhager 2005-01-17 20:21:28 UTC
i see this on FC3

Comment 6 Oliver Jones 2005-01-24 03:57:20 UTC
I see something similar to this on Fedora Core 3 with kernel

I have a HP nx7010 with an Intel AC97 codec (Analog Devices AD1981B).

lspci output:

00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
00:1f.6 Modem: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97
Modem Controller (rev 01)

With the latest kernel installed via yum I can only get audio output
on the headphone jack of my laptop.  The internal JBL speakers do not
make a peep.

Interestingly the Gnome Mixer (and alsamixer) don't adjust the
headphone volume when I twiddle with the value of the "headphone" slider. 

The external amplifier slider doesn't exist but the "mute" check box
makes the mute LED on the laptop light up.

On older kernels the speakers worked fine and so did the headphones. 
The speakers would shut down when I inserted the headphone.  I haven't
done any comparisons in mixer behaviour though.  My solution to the
problem has been to stick to using kernel 2.6.9-1.681_FC3.  But I'd
like to use 2.6.10 if I could as it has new bits and bobs that might
make getting other hardware in the nx7010 to work easier.

Comment 7 Dave Jones 2005-04-16 04:47:21 UTC
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
