I got RC3 of Alsa to build by specifying that it only build support for my sound card. I did a "./configure --with-sequencer=yes --with-cards=sbawe" and that left out the offending code. However, it acts exactly like Beta 12 did. It still slows the sound down to a crawl randomly, and now I've figured out that it also randomly makes recordings into noise. I am absolutely disgusted with Alsa. I don't think it's ready for production and including it in the kernel is a very bad idea IMHO if this is its current state. Given that it has had several years to develop, I would expect something usable by now, but as far as I'm concerned, it is completely useless. I don't know how you guys have ever gotten any good out of the thing. Maybe it's just broken with the AWE64.
