Hey @mitr,
I am so sorry it’s been three full weeks that we’ve missed your post 
. I’m hoping this will not happen again.
Sorry to hear about the trouble! Yes, Roon supports MQA (all the details are here) and it shouldn’t crash when trying to stream MQA files.
If this is something you’re still running into, could you please let us know? It’d be great if you could please include the details we ask for here.
