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. ====================================================================== ---------------------------------------------------------------------- tiwai - 01-18-05 11:32 ---------------------------------------------------------------------- Try 1.0.8. Some hardwares have a bug in reading DMA pointer register. The latest ALSA version has a workaround. ---------------------------------------------------------------------- rlrevell - 01-18-05 21:25 ---------------------------------------------------------------------- I think this is an mplayer bug. I get the same behavior - it's unusable with ALSA output because they reset the stream on every xrun, and xruns are inevitable because they don't use a separate RT thread for audio. Try oss emulation, mplayer -ao oss. This works for me.
