There is a little wierditude with sound. I've seen X grind to a halt on a 300MHz G3 with smaller buffer sizes - which may just be a manifestation of the more general problem: Quote from Geert "Richard Zidlicky found a bug that made the driver always use 1 byte buffers, which gave very bad results on slow machines. It was fixed in 2.3.x." I'm on the case of back-porting the 2.3.xx dmasound stuff to 2.2.17pre7 - but don't hold your breath (there's a lot of understanding to gain on my part - because the sleep queue stuff changed).
