Created attachment 342905 [details] output from "alsa-info.sh" I loaded Fedora 11 Preview on my laptop. Although the sound card appears to be recognized (e.g., it's listed in /proc/asound), all utilities behave as if there is no sound card present in the system. E.g.: $ alsactl init alsactl: init:1708: No soundcards found... $ alsamixer -c0 wrong -c argument '0' Note that the "alsa-info.sh" output claims that pulseaudio isn't running, but that is most decided false: $ pulseaudio E: pid.c: Daemon already running. E: main.c: pa_pid_file_create() failed. $ ps fax | grep pulse 3967 ? Ssl 0:00 /usr/bin/pulseaudio --start --log-target=syslog 3968 ? S 0:00 \_ /usr/libexec/pulse/gconf-helper

It is doing pgrep /usr/bin/pulseaudio, which yields nothing. Either 'pgrep pulseaudio' or 'pgrep -f /usr/bin/pulseaudio' would work. Might be good to file a bug against alsa-utils about that.
Seems to be an ALSA problem. Could you please attach the strace output of 'amixer -c0' here?
The last batch of updated alsa packages in Rawhide (1.0.18-3.fc11) seems to have fixed this. For now, I'm going to close with RAWHIDE; if I see problems again, I'll reopen and provide "amixer -c0" output. (The bad use of pgrep was also fixed in the latest alsa-utils.)
