Description Mark 2005-04-07 03:50:59 UTC
Description of problem:
A clean install of Fedora Core 3 Distro downloaded around 3/24/2005, most files
last modified time is 11/3/2004 - with kernel 2.6.9-1.667.

Motherboard: Soyo SY-P4RC350
CPU: Intel Celeron D 2.8Ghz
RAM: 512MB
HDD: Seagate Baracuda 250GB ATA133
Sound: Integrated AC'97 6 Channel sound
Video: Onboard (not in use), Radeon 9600 Pro AGP (in use)

After initial package installation with kernel 2.6.9-1.667 (clean system)...
-Sound config plays sample sound without any further modifications (i.e. sound
works on first boot after setup/install)

Via apt package installer, upgrade all components, including kernel. Kernel
upgraded to 2.6.10-1.770_FC3...
-Sound does not work.

Attempts made:
1. Unmute all sound devices via alsamixer, aumix, amixer, and Gnome GUI sound
mixer. Also combinations of mute/unmute have been tried for unfamiliar devices
(like IEC958). Also, there is no "auto sense headphone jack" volume control -
tried that.
2. Boot with the following arguments: acpi=off, acpi=noirq
3. Disabled acpid in all runlevels
4. Modify /etc/modprobe.conf. Remove default distro entries and replace with
suggested entries from (for the atiixp chipset).
5. Copied /etc/asound.state from a 2.6.9-1.667 boot, to /etc and chmod 400 (in
hopes that it won't be overwritten).
6. Tried plugging in headphones

All attempts yield the same result - sound works in 2.6.9-1.667, sound does not
work in 2.6.10-1.770_FC3.

I've searched bugzilla and numerous other forums (, to name a few) and none of the fixes for anything similar to
this issue worked.

Thanks in advance for your time.

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

How reproducible:
Every time

Steps to Reproduce:
1. Install Fedora Core 3 kernel 2.6.9-1.667 (on system using Soyo SY-P4RC350
motherboard and integrated AC'97 sound)
2. Test sound - sound test successful
3. Update kernel to 2.6.10-1.770_FC3
4. Test sound - sound test failed
Actual results:
lspci shows sound modules loaded (snd-atiixp) for both kernels.
the system (using aplay or xmms) "seems" to play sound, but no sound coming from

Expected results:
sound should be coming from the speakers

Additional info:
In attachment find output from each kernel boot for lspci, dmesg, and lsmod.

Did you try to executed alsaconf?

> Did you try to executed alsaconf?

Alsaconf adds some lines to /etc/modprobe.conf (included below). I've tried
booting when modprobe.conf only includes the lines added by alsconf and I've
tried booting with the modprobe.conf included below. No sound with either. It
seems that sound is "working", but nothing is coming out of the speakers. And
again, booting to the 2.6.9 kernel, sound is fine.

Thanks again for your time.

It's realy hard to say where is the problem, because 2.6.10-1.770_FC3
and 2.6.9-1.667 have the same alsa-drivers (1.0.6). I'll check if
there is any diference, but i think that isn't.

Or you can try to use 2.6.9-10 kernel from devel, with alsa-drivers
1.0.8, it maybee can help. (In this case, you will need alsa packages
- lib&utils from devel)

I've seen the same thing with my eMachines M2350 laptop --
kernel-2.6.9-1.678_FC3 works with the builtin speakers, while any later kernel
does not (the first one that I have that doesn't work is
kernel-2.6.10-1.741_FC3),   Note that the headphones work with all kernels, it's
just the speakers that no longer work.

Comment 7 Martin Stransky 2005-04-20 10:31:11 UTC
You can fill bug report for alsa-project
(, but I think better can be upgrade to
new alsa drivers in Fedora 4...

Comment 8 Martin Stransky 2005-06-20 16:09:41 UTC
Any news with the new FC release?

Comment 9 david d zuhn 2005-06-20 16:24:45 UTC
I have checked FC4, and I don't have sound via the builtin speakers. 
I have not had a chance to check the headphone jack.

Comment 10 Martin Stransky 2006-01-03 15:29:38 UTC
Some how-to for the latest alsa-driver and FC4 is here:
