[SOLVED] No audio for Spotify with USB DAC

[thexperiments]

Hi,
I was running a 6.x moOde for some time now and it was working OK.
As I saw the release some days ago I thought I sholuld give 7.2 a shot.

Setup was quite smooth and after configuring the output device to the USB DAC in the mpd config via the web ui I could listen to radio and local media just fine.

However when trying out spotify and airplay (main purpose for me) it looked like it was playing fine but I could not hear anything.
I got Airplay to work by setting the bitdepth to 32 as I saw that my dac might only support 32.

Spotify is still not working (it was working on 6.x)
