[linux-audio-user] Replacing Alsa driver in 2.6.8 kernel

Hi, I wonder if anyone has a pointer to any web instructions on how to replace an Alsa driver that has gotten broken in a new kernel release. My ATIIXP sound chip has worked fine for months but suddenly it's broken in a number of 2.6.7 kernels as well as 2.6.8-rc2. It appears that a broken driver was released without testing, if I understand the Alsa Bug Tracker correctly. Now there are comments about replacing the driver in the kernel with the driver from CVS. I don't know how to do this. Sorry for bringing this issue here but I'm hoping to get a simple answer before I go join yet another mailing list for a one time event. Thanks in advance, Mark
