[PROBLEM] Issue with sound card that have multiple device

[beanxinh]

You need to restart MPD after changing ALSA conf.
sudo systemctl restart mpd

If there is more demand for cards like the Xonar device I could add to the TODO list but at minimum I'd need a sample device for testing.

Sorry I forgot to mention it in the previous post but after I changed the _audioout.conf I did restart MPD using "systemctl restart mpd" I also try reboot the pi .

audio_output { type "alsa"
name "ALSA Default"
device "_audioout"
...}

If I change the mpd.conf file and replace "_audioout" with "hw2:1" I can change the output of MPD after restart the service or reboot but spotify remain the same( they are different service after all).
