The card is correctly recognized and set up by the PnP drivers. The system freezes completely when using sound (no ping replies anymore), and it's not a CPU/motherboard/RAM issue (it compiles kernels without any problems), it occurs while playing MP3's, while playing LxDoom ( now i have an excuse to play Doom, testing the Linux sound drivers ;) ). The time after which it crashes is variable, sometimes it crashes immediately, sometimes it crashes after 5 minutes. Sometimes, it also stalls a few times before finally crashing. Having persistant DMA buffers enabled/disabled doesn't change anything (the machine has 16MB of RAM), and the problem occurs both when using modules or compiled-in drivers. Both 2.4.8 and 2.4.9 have this problem (these are the ones I tried). Btw on 2.2.x i get DMA (output) timeout errors (and broken sound). There is also another "issue": the ISAPnP code calls "CMI8330 quirk". As i have no such card, i thought this was related to the problem. After commenting it out in quirks.c and recompiling, the quirk was not called anymore, but it didn't solve the problem. greets
