Maybe it would be possible to expose the hardware mixing as engines on the
first node? That would allow multiple clients regardless of vmix. IIRC, all
that's required is setting the ADEV_SHADOW flag?
Now, It might be a hassle to reconfigure programs to use /dev/dsp again for
users used to the multiple nodes, but if ADEV_SHADOW is changed to also expose
the engines as separate nodes while still placing the multiple engines on the
first node, reconfiguring won't be neccesary. This small patch (untested)
should do it:
