Sounds reasonable. Too bad I have no Mac with snapper and an actual line
in ( hmm, adding one shouldn't be hard, just ugly and I don't really
feel like ripping my iBook apart )

Sorry, didn't get around to play with it yet. Do you have the data sheet
or did you get everything you know about the chip from snapper* ? ( the
data sheet is available from ti.com or I could just mail it to you ).
I'm not at all sure snapper_write_mixer() does The Right Thing(tm) in
all cases ( most likely my fault - the regs[5] =3D ... line should
probably be regs[6] =3D ... )

have fun
Michael
