Description of problem: Sometime recently I "yum update"d my F8 box. After this update, all songs sound like they are sung by the chipmunks -- the playback is too fast. After some debugging on #pulseaudio we concluded that this is an alsa problem. (I disabled pulseaudio and used mplayer's alsa back end to verify the problem remained.) Version-Release number of selected component (if applicable): opsy. uname -a Linux opsy 2.6.25.6-27.fc8 #1 SMP Fri Jun 13 16:38:52 EDT 2008 i686 i686 i386 GNU/Linux /proc/asound/cards says: opsy. cat /proc/asound/cards 0 [I82801BAICH2 ]: ICH - Intel 82801BA-ICH2 Intel 82801BA-ICH2 with AD1885 at irq 17 opsy. grep 'front DAC' /proc/asound/card0/codec97#0/ac97#0-0 PCM front DAC : 48000Hz Also, saw this in /var/log/messages: Jun 29 08:58:03 opsy kernel: intel8x0_measure_ac97_clock: measured 50944 usecs Jun 29 08:58:03 opsy kernel: intel8x0: measured clock 78 rejected Jun 29 08:58:03 opsy kernel: intel8x0: clocking to 48000 This looks vaguely like this alsa bug report: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=69
Same problem for me after updating to kernel-2.6.25.9-40.fc8 Adding this line to /etc/modprobe.conf fixed it for me: options snd-intel8x0 ac97_clock=48000 See also https://bugzilla.redhat.com/show_bug.cgi?id=441087
