Have you tried the RAW/PCM switch in the DAC settings? Wi-Fi and hires files can be problematic with Audirvāna, even with Ethernet connections I couldn’t play longer 24/192 files past approximately 3/4
Definitely disable any upsampling
You should post up your debug so forum can perhaps help further
I have the same problem to night with dropouts when playing Tidal. Sometimes lasting several seconds. Never happened to me before. Very annoying.
