TBH setting up ALSA is usually pretty simply for playout. The problem is
generally the lack of documentation. But for future reference there are
pages on my Audiomisc site that explain how to set up ALSA for quality
audio replay. The hardest bit can be stopping Pulse from then 'nannying'
you and changing what you set.

Okay. With the help of your page + a bit of rejigging, it's getting close. I
realised I also needed a sound editor, so the sound files now live on a hard
disk plugged into the backend raspberrys; and alsa now recognises the DAC as
default, mpd plays, audacity sees the DAC directly and plays, all the other
usual players seem to find alsa and play, even amarok, which I was nervous
of.

Except that there is something up with samplerates, I'll follow that up to your
other post, later.
