I tried playing using xmms, mplayer and others. From lspci I see, it is an ATI IXP 150. I understand that this bugreport alone won't help you guys, so if I can give any more info, pls let me know. When playing movies with mplayer, I see lots of messages like: alsa-play: xrun of at least 0,131 msecs. resetting stream% 0% 0,0% 1 0 0% alsa-play: xrun of at least 0,026 msecs. resetting stream 0% 0% 0,0% 7 0 0% These appear even more where skipping back and forward in the movie. I found, that playing movies through SDL helps a little, but sound is still choppy and cannot be listened to. ====================================================================== ---------------------------------------------------------------------- rlrevell - 01-21-05 19:13 ---------------------------------------------------------------------- Did you ever try OSS emulation? I still think it's an mplayer bug. ---------------------------------------------------------------------- feixm - 01-22-05 13:30 ---------------------------------------------------------------------- Yes, I tried OSS emulation in my very first attempts to solve this problem. Since I've found, that there is no difference in using directly Alsa or indirectly alsa through OSS emulation, I completelly stoped to compile programs with deprecated OSS support. So, the answer is - yes, I tried OSS emulation about 3 months ago, when I installed Linux on this notebook and discovered this problem. Another note regarding Mplayer. It's not only mplayer, it's XMMS, it's virtualy everything in my KDE desktop, which is using ARTS daemon, which in turn is configured to use Alsa, or OSS few months ago. No matter what I use, the symptomps are still the same. Everything is fine, say for about 3 to 10 minutes (this is VERY random), that suddenly sounds gets scrambled for few hunderds of miliseconds up to two seconds and then it continues to play normaly. After random number of seconds (minutes) it happens again. Yesterday I've installed into my XMMS a crossfading module. When it's set up to use Alsa as output device, it plays "fine", with the behaviour described above. But when I use ARTS as an output device, it plays one second of music, then it skips about 10 seconds, plays another second of music, then skips another 10 secods... Looks like it's filling some sound buffer but the buffer gets flushed sooner, then it's actually played. When using ARTS as direct output (without Crossfader module as intermediate) it plays "fine", with the mentioned behaviour. Maybe this helps, maybe it's a description of a XMMS or ARTSd bug and it has nothing to do with this problem. Who knows. I definitelly don't :).
