[linux-audio-user] ice1712 dshare asoundrc

[shulmang at colorado.edu (Garett Shulman)]

I would really like to do hardware mixing since my card should support 
it. I have been hacking away trying to google and decypher the plugin 
docs and have created the following asoundrc. However, when I try to run 
a second instance of fluidsynth on 44_2 I get the following error:
ALSA lib pcm_dshare.c:800:(snd_pcm_dshare_open) destination channel 
specified in bindings is alread used. I'm not sure what I'm doing wrong. 
Is alsa simply not capable of taking advantage of the ice1712 hardware 
mixer? Here is the asoundrc I have so far.

pcm.44_dshare {
     type dshare
     ipc_key 42892323
     ipc_key_add_uid yes
     slave {
         pcm "hw:0,0"
         period_time 0
         period_size 70
         periods 24
         buffer_size 1024
         channels 10
     }
     bindings {
     0 0
     1 1
     2 2
     3 3
     }
}

pcm.44_1 {
     type plug
     ttable.0.0 1
     ttable.0.1 1
     slave.pcm 44_dshare
}

pcm.44_2 {
     type plug
     ttable.0.2 1
     ttable.0.3 1
     slave.pcm 44_dshare
}
