From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; sv-SE; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: I couldn't get S/PDIF-out working (no sound) with alsa-lib-1.0.9rf-2.FC4 and EMU10k1 on my SB Live Value. Downgrading to alsa-lib-1.0.6-3 (FC3) solves the problem. I also removed /etc/asound.state to make sure that the volume control settings didn't mute output. (Analogue output works.) Version-Release number of selected component (if applicable): alsa-lib-1.0.9rf-2.FC4 How reproducible: Always Steps to Reproduce: 1. Connect the S/PDIF output to an amplifier 2. $ aplay /usr/share/system-config-soundcard/sound-sample.wav Actual Results: No sound was produced on S/PDIF output. Analogue output works. Expected Results: Sound on S/PDIF output, as with FC3. Additional info: Downgrading to alsa-lib-1.0.6-3 (FC3) solves the problem.
Do you use FC4 kernel with old alsa-libs?
Yeah, I use FC4 with alsa-lib-1.0.6-3 (taken from FC3).
What do you have in /etc/asound.conf when sound works?
# Generated by system-config-soundcard, do not edit by hand defaults.pcm.card 0 defaults.ctl.card 0
Do you use only snd-emu10k1 driver? Could you attach output of lsmod and "aplay -l"?
What happens if you install new alsa-lib and fill /etc/asound.conf with pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }
$ cat /etc/asound.conf # Generated by system-config-soundcard, do not edit by hand # defaults.pcm.card 0 # defaults.ctl.card 0 pcm.!default { type hw card 0 } ctl.!default { type hw card 0 } $ rpm -qa | grep alsa alsa-utils-1.0.9rf-2.FC4 alsa-lib-1.0.9rf-2.FC4 alsa-lib-1.0.9rf-2.FC4 alsa-lib-devel-1.0.9rf-2.FC4 $ reboot *** No sound ***

Kernel version is at all times: $ uname -r 2.6.11-1.1369_FC4
