[alsa-devel] How much of the X-Fi (emu20k1) chip has Creative documented?

[Brendan Pike]

Its impossible for me to be using dmix as dmix isn't even compiled into
my alsa-libs.

I'm 100% sure that HwMix is supported. When I said direct hardware
access I meant it. I'm sure anyone else with an XFi card can confirm
this too.

Calculating dependencies... done!
