hmm, in the case of PCI cards, the built-in driver should work without problems. in the case of ISA non-PnP cards, passing parameters is a bit difficult, though. > 2) For alsa to work in kernel 2.6, the first item in the OSS menu has to > be set to M, otherwise module soundcore does not seem to exist.

JFYI: in the future version of 2.6 (once Rusty's patchset is merged), aliases can be removed from /etc/modprobe.conf, since there are built-in aliases now. > f) check /etc/modules.conf is not still trying to load OSS drivers. > g) Make a simple test, by playing some white noise out of each speaker > in turn, allowing for up to 6 speakers.
