Do you still get the bad skips? Just copied to a tmpfs, and it still skips badly.
in response to your question, Ingo, yes, i see those atleast 0 ms messages. I am not running esd, i use alsa directly from ogg123. but its not just ogg123, mplayer does it too. just moving a window can trigger it. even scrolling in my maillist causes it. and this ONLY happens on cfs, not vanilla, not staircase, not sd. while i look at top, the load average is 0.11 its definetly not an IO issue, cause i just tried creating some IO load, like reading files, it doesent skip, but moving windows triggers it better than anything(mplayer seems more sensitive than ogg123), it seems anything X-related makes it explode.. tried looking for buffer stuff in /proc/asound, couldnt find anything, im using the via82xx driver. > > Ingo > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
