[SOLVED] Stuttering MQA via USB DAC

[zainframe]

@zainframe

Candidly, I was hoping your issue could be traced to the LAN, servers, etc., because then I could make some practical suggestions for them.

Since it appears to relate directly to the E50 and moOde (plus RPi3B+ of course) there's little I can suggest other than to double check you don't have some content-altering settings in play. I have no MQA-capable DAC to test with so there's nothing I can "try at home." 

When I search the InterWeb™ with phrases like "MQA stutter" I get hits which suggest timing related-problems (clocking, buffer underruns, etc.). There seems to have been some related posts on the audioscience.review.com forum.


Substituting in an RPi4B is a bit of a Hail Mary pass but certainly if you have one try it.

I was thinking it could be USB jittering issue due to the Pi3 USB sharing the same bus as Ethernet etc but since network is not being used (I am on wifi anyways) the USB is probably using the BUS exclusively (not sure about this though). No issues with DSD even the high bitrate ones so it cannot be bandwidth related.

Is there anything I can test/configure on the MPD side? It looks like the DAC keeps loosing the MQA signal for split seconds- anything I can check to ensure I'm sending bit perfect to the DAC?

Thanks
