I tested this on three different soundcards in two different systems. However I have since found my conclusion to be wrong. The IRQ issue might have been part of the problem, although I cannot say this for sure. The important thing I have noticed is that the problem gets worse over time! Immediately after booting up my system, sound is - from what I can tell - smooth and without (or with very few) hickups. However after a few hours it starts coming back, and at this point - after a 4-5 day uptime - it's completely impossible to listen to any kind of music. Every second or so it sounds as if the soundcard buffer is repeating itself for a fraction of a second, giving me a sort of 'rrrr' sound. It sounds just like when I close the lid of my laptop - it's as if all the hardware in the system just freezes up for 0.1 seconds. However in this case it's only the sound .. Everything else seems and feels smooth. This has been a problem since I installed FreeBSD 5.0 a long time ago, and we're now at 5.2 and the issue still hasn't been resolved. I've tested on three different sound chipsets so far (CMI, Crystal and EMU10k1), and they all display the same problem - although to a varying degree. I really hope someone can look into this (again) soon - I for one will be very happy to help debugging. Working is hard without music, especially when everyone around me is making as much noise as they usually do... :-/ I'm *not* using INVARIANTS or any other debugging options in the kernel. Still hoping ;) /Eirik
