[PROBLEM] MPD and CamillaDSP errors

[gwurb]

I know very little about DSP or Camilla but from your post the 'buffer under-runs' seem to be a feature.
Have you increased the buffer in the audio set-up ? mpd-settings.

Someone more conversant than I will be along soon I expect :-)

I did increase it to 16MB. Decreasing it back to 4MB doesn't fix the problem. It changes how long I can play the track before skipping for the error to occur. Here is a CamillaDSP log example with 4MB MPD buffer and going from track to track.

Code:

The question, really, is why are buffer underruns occurring AND resulting in MPD error in Moode. When I was playing with CamillaDSP settings I noticed that at least one of them does not apply on Moode when I select Apply to DSP. It seems to apply but then if I choose Fetch from DSP then the wrong value is returned. So Moode's interface/implementation to CamillaDSP is not generic.
