hi lee,

well, things are going *absolutely magnificently* with your emu10k1
patch - i haven't really tested it at 128 frames, but it works
brilliantly at 256 (i've tested it running ardour, hydrogen, muse, and
two vst plugins + vkeybd at the same time - incredible!).

my only problem, now that i've sort of got the hang of things, is
recording - i don't seem to be able to isolate the ac97 input as before
... when i try to record guitar or vocals over other tracks in ardour,
it keeps mixing the pre-recorded stuff with the line input stuff!! i'm
sure it's just a mixer setting i have to adjust, but i don't know which
.... it certainly doesn't seem to be the same adjustments i had to make
before the patch?

so, can you tell me how to isolate the ac97 channel?

(in qjackctl, i have only inputs 1 + 2 connected, going into ardour's
inputs - not sure if these are the right two out of the 16 on offer).

cheers
