the old Indigo DJ driver worked after a few tweaks...
tested w/ jack, cmus, mplayer
mapping/virtual-outs seem good..
this is a diff on alsa-kernel.git. copied the old firmware and amazed it works, although something seems wonky with the samplerate registers. going to email echo about an updated firmware .. no noise bursts or ear destruction tho!
