You may want to try this CamillaDSP config. It does polarity inversion and uses the nice CamillaDSP volume control with dither for 16 bit.

Hi Tim,

I created the file and it is recognized when I selected it and the configuration process went without objection. However, songs would not play with an MPD error 'Failed to open audio output'. I expect I'm missing something simple.

Also, a simple question: I have files with a variety of sample rates, bit depths. Mostly flacs with a few mp3s and others. Will this CDSP configuration work on all of them?

thanks,
Skip
