[Alsa-user] how can I start the dshare server separately from applications using it?

[Kevin Seghetti]

I am working on a multiple stream jukebox program (plays 3 separate
stereo streams out a 5.1 sound card, in this case the EPIA-VIA-M). Each
stream uses aplay to play a song, when it finishes it calls aplay again
with a new song. I am using dshare to multiplex 3 copies of aplay into
the sound card (asound.conf file attached). It plays all 3 streams
great. The problem I am having is whichever stream I start first causes
the dshare server to spawn, and it doesn't return until all streams have
stopped playing (whereas I need it to return when the song finishes so I
can start another one on that channel). 

So I think what I need is a way to start the dshare server separately
before I start any of the aplay tasks so that the server is not tied to
any of them.

Anybody have any ideas or suggestions? I am sort of in a bind because
this product is to be shown at CES in 3 days and we just noticed this
behavior.            

Thanks in advance,
