I created a /etc/modprobe.d/options.conf with options snd-intel8x0 ac97_clock=44100 and after reloading the driver, the playback was 10% too *slow*. Using options snd-intel8x0 ac97_clock=48000 it's correct, but then still 10% too fast after suspend/resume. So I don't think it's that parameter. Here are the other parms: parm: index:Index value for Intel i8x0 soundcard. (int) parm: id:ID string for Intel i8x0 soundcard. (charp) parm: ac97_clock:AC'97 codec clock (0 = whitelist + auto-detect, 1 = force autodetect). (int) parm: ac97_quirk:AC'97 workaround for strange hardware. (charp) parm: buggy_semaphore:Enable workaround for hardwares with problematic codec semaphores. (bool) parm: buggy_irq:Enable workaround for buggy interrupts on some motherboards. (bool) parm: xbox:Set to 1 for Xbox, if you have problems with the AC'97 codec detection. (bool) parm: spdif_aclink:S/PDIF over AC-link. (int) parm: enable:bool parm: joystick:int Not sure if it's worth trying any of the others. > > The alsa-utils initscript is somewhat misleadingly named.

(I thought it might be merely the fact that the driver had a use count of 1 from pulseaudio [PA} that was relevant. So is the bug in the driver or PA?) BTW not surprisingly, the effect is also evident in Flash video. ** Attachment added: "pulseverbose.log" http://launchpadlibrarian.net/35537479/pulseverbose.log -- Playback 10% too fast after resume https://bugs.launchpad.net/bugs/480010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
