I seriously doubt I'll be able to help much beyond this point since
I can't test any of this myself.
Though I might get some ideas if you can give some additional
E.g. does it play all audio, just with pauses, or does it actually
drop parts of the audio?
Does the receiver indicate in any way it has issues synchronizing or
Does the status-line "A:" counter increase smoothly or does it reflect
Or are the pauses too short to be noticeable there? Have a course
Probably a bit overkill, but possible a recording of the output
might give some insights?

Hm, these sample rates/channels do not fit together.
I don't know if ALSA even cares about that information though...
