Is it possible to make all 4 ins/outs in the Audio 4 DJ available through the first substream device?
A user was having trouble using the NI Audio 4 DJ device with jackd. When jack connected, this 4-in/4-out device would appear as 2-in/2-out. This was the result of the fact that the channels are split up into stereo substreams. I.e. the first two channels are found in hw:x,0,0 and the last two channels are in hw:x,0,1.
The work-around was to use the `multi' plug-in to make these 2 PCM's appear as a single PCM.
There's several situations where this is a Good Thing, because it makes it easy for the user to treat the streams independently.
BUT... in the pro-audio case this is not a good thing at all.
Ideally, substream 0 would support 1, 2, or 4 channels (for both playback and capture). When substream 0 is using more than 2 channels, then substream 1 would return EBUSY when in use.
So... would it be possible to do this in the caiaq driver?
