[PROBLEM] XRUN in CDSP when playing via USB input

[PaulE54]

Tim, first of all many thanks for responding so quickly. 

Secondly, that seems on a quick test to have cured all the stopping / having to restart, and USB input and Camilla now seem to be playing nicely together. 

I did check the MPD log and it's got loads of warnings -  
"CDSP Plugin WARN: IO Thread out of data".
But they are not as far as I can tell affecting the audio, and there are no errors that I can see. 

So I've turned off MPD verbose logging ;-)

Thanks again

Paul
