Is it possible to change Flash's audio device channel?

[auricle]

I am using PC-BSD 1.4.1 with 4Front's OSS (not the one in ports). I have assigned different sound playing programs (aRTs, Kaffeine, Amarok) to different virtual mixer channels i.e.

aRTs on /dev/dsp13
Amarok on /dev/dsp12
Kaffeine on /dev/dsp11

The only problem is that the sound on any flash websites (youtube, etc.) doesn't work and after trying a website if I try to start kaffiene or Amarok it says that the audio device is busy.

How can I assign flash to its own virtual mixer channel?

Has youtube audio ever worked with oss?

I don't understand why you would want to allocate vmix channels to individual applications. Applications outputting audio to /dev/dsp should automatically pickup the first available vmix channel.
