@scolley i had probably the same (or similar) issue with previous Bridge2 code and Huron - e.g. not MQA files, by any FLAC file - be it local or Tidal.
As my bridge is currently RMA i can’t confirm if it persist or not with latest firmware.
Please check this thread:
From my troubleshooting it seemed like Bridge2 is somehow overloaded (buffers full or something like that) and not accepting further data. Unfortunately I do not have any update from Roon folks…
