May be. But why it occurs only with selected cards?.. I tried to play with pci aureal 8820 card and had a fresh sound in contrast to cl4135, but snd_au8820.ko, based on ancient binaries released by dying company is too buggy and unstable. :( So, I'd say that may be something wrong in "simple SB16" code... I'll be very appreciate If anybody suggest me any idea about how and where I should dig this trouble. Yan.
