No, you don’t have to select the device - it will just “copy” the output to the bluetooth device within alsa. I am using the audio-jack as output device within volumio.
Some things you can double-check:
- Did you reboot the pi and tested again?
- Did you modify the file “mpd.conf.tmpl”?
- Did you replace the placeholder xx:xx… with the correct address of your device? (the same you used for aplay)
- Please check the (generated) file /etc/mpd.conf - your modifications should be placed there automatically. If not, edit it manually according to the template and restart the mpd deamon.
- Maybe the device is disabled or muted within alsa - you can use the mixer to check that - I don’t know the concrete commands - but google will…
I hope, these hints will help you a little bit further…
…good luck and best wishes for success!
