New DAC three days ago?

I have Spotify Connect2 3.0.7, Volumio v3.198, DAC Asus Xonar Essence STU (with volume knob)

For me, Spotify Connect works only if I set Mixer Type to NONE in Settings. This might be worth trying, if you haven’t already.

Note: From time to time Volumio insists on changing the setting to HARDWARE, and then Spotify Connect fails, until I change it to NONE again.

When mixer type is hardware, Spotify Connect2 fails, log below:

nope, no new hardware.
But I now tried and reset default output to my d10 again and spotify connect started working.
so thanks alot.

@balbuze Any idea, why spotify connect does not work with setting Mixer type = Hardware for my setup (log above)?

Probably because the mixer set in the plugin is not correct… Please send a full log link. Thanks

I sent a log link as private message. Thanks.

I had same problem. Changed mixer type to ‘none’ - magically fixed. Thanks for the tip.

Aaaand now it’s gone again.
