I'm trying to run squeezeslave in the background when using XBMC and sending audio through my optical output. Unfortunately if I start XBMC first, the digital output is not available to squeezeslave, it just doesn't even show up in it's available output device list. Likewise if I squeezeslave first, XBMC can't see the digital audio output.
I used the info from this thread to create an asound.conf file, and while dmix0 became an available device, the behavior is identical, if either one of the apps is using it, then it is completely unavailable to the other, by that I mean it doesn't appear in the list of available devices.
Here's the relevant output from aplay and squeezeslave -L. This output was generated by starting squeezeslave first, so it works, but XBMC now has no audio.
If XBMC is run first and using the digital output then squeezeslave -L doesn't show the lines beginning with 1, 12, 13, 15, and 16.
And my /etc/asound.conf file:
I commented out the rate line and the ones below it because squeezeslave crashed when using dmix0 with an error saying the rate was invalid.
