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. Hardware: 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 alsa-project.org (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 (fedoraforum.org, linuxquestions.org 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 speakers. 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?
(In reply to comment #2) > 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. ##### alias eth0 via-velocity alias snd-card-0 snd-atiixp options snd-card-0 index=0 install snd-atiixp /sbin/modprobe --ignore-install snd-atiixp && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-atiixp { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-atiixp alias usb-controller ehci-hcd # --- BEGIN: Generated by ALSACONF, do not edit. --- # --- ALSACONF verion 1.0.8 --- alias snd-card-0 snd-atiixp alias sound-slot-0 snd-atiixp # --- END: Generated by ALSACONF, do not edit. ---
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.

You can fill bug report for alsa-project (http://www.alsa-project.org/), but I think better can be upgrade to new alsa drivers in Fedora 4...
Any news with the new FC release?
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.
Some how-to for the latest alsa-driver and FC4 is here: http://people.redhat.com/stransky/alsa/
Please reopen if you have some new info...
