Not sure if this has been mentioned or not, but if you go into the settings for your DAC in the Tidal settings area, and ensure that the 'MQA passthrough' option is not ticked, the Tidal desktop app will decompress the stream on the fly to 24-bit, 96kHz.
I looked in the settings area of Tidal, but didn't see any settings for my DAC nor did I see the "MQA passthrough" option.
