kszaq Don't know if you saw my post before, but spotify connect web doesn't work with the built in sound drivers for the 905, but will with an external usb headphones, so something isn't right with the ALSA mixer in your build.
Here is when I run the config wizard, and select the USB sound device, I can then pick a mixer, and all works well.
When I try to pick any of the options for the 905 sound via HDMI, I get no mixer selection, and the service doesn't start.
Since it's capable of working with USB sound, it has to be something simple. Any ideas.
