Hi. I am having a play with mopidy as I am building a music streamer. I can get most of my test tracks to work and Tidal but having some trouble with my (downloaded from Tidal) EAC3 Dolby Atmos file (specifically Madonna’s Immaculate Collection). I have set up PulseAudio (which I hate) and checked EAC-3 bitstrem using pavucontrol. I can in DD+ using gstreamer directly as follows:
gst-launch-1.0 filesrc location=01\ -\ Holiday.m4a ! ac3parse ! pulsesink
This plays as Dolby Atmos - DD+ 48 kHz on my Denon AVR. However, ac3parse is required in the pipeline, and I think this may be the issue?
When playing using mopidy, it is played as stereo 48kHz. I have tried running mopidy as both a user and as a system, both with the same result.
with GST_DEBUG=2 mopidy I get the following:

I guess this is expected from mopidy? Is there any patches I can try? I was hoping that mopidy / gstreamer can output digital audio via HDMI using alsa but I don’t think this is possible? I would like to avoid pulseaudio - I hate it! Alternatively, is there any way to get mopidy to direct the file to another player (mpv works perfectly direct to alsa).
Thank you.
