And FWIW, this happens continuously, not just in the 25 seconds (or > whatever) after playback starts. I have a Envy24 ICE1712 based card also. I have noticed the same thing. I would say in the first 25 seconds I can't do anything with my machine without getting a skip. But after 25 seconds, it is pretty good. Pushing my machine hard, lots of disk or X activity can induce small skips after that 25 seconds (I've been meaning to try the new scheduler patches). I'll agree that larger buffers are not the answer. I sometimes mess with live audio effects. That is recording some audio, processing it in some way, and then playing it back. If the buffer is too large, a noticeable delay would be introduced. Takashi and Jaroslav I'm pretty sure know the problem this causes with musicians, who need to hear what they played or sang in a very short period of time, or it messes with the brain. I'm just not sure all the kernel developers are also aware of this effect. It is more than just not having to wait a minute to hear the effects of an EQ change. -- Chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
