You just leave the I2S config in place and your USB audio device plugged in and then switching between the two is a matter of editing mpd.conf and then restarting MPD.
That's cool. Makes sense now that I think about it.
Quote:When both devices either support hardware volume or neither device supports it AND they both use the default ALSA mixer names of Digital (I2S) and PCM (USB) then the edits are straight forward. It gets tricky when non-default ALSA mixer names are used or when One device is configured to use hardware volume and the other software volume, etc etc.
ALSO - watch out for volume when switching outputs.
Fortunately we have you to wrestle with the devil in the details
It wouldn't bother me if volume were always forced to zero when switching. Better the minor inconvenience of readjusting it than a major pain to ears and/or transducers.
