I asked because I'm using the emu10k1 driver and I've noticed frequent bizarre behviour when watching videos in xine AND mplayer... While this could be written off as a xine bug, my friends who have other audio cards can watch the same files without issue in both media players. I hadn't thought much of it, until now. So here's the low-down... I'm thinking there are some bad bugs in the emu10k1 driver (not surprisingly, it's given me problems for *4* years, using OSS and ALSA, though I must say the OSS driver seems to be ALOT better). For completeness could you test the OSS emu10k driver (which supports PCM, while the ALSA driver does not) and see if you experience better overall performance? Like less CPU utilization etc... I'm very interested in finding out where the bottlenecks are. The emu10k1 driver isn't perfect and neither are xine or mplayer so I'd like figure out what exactly is going on here. I'll of course do the same. It's just kind of hard to judge for me seeing as my system is now 4 years old. -sb
