I have a QNAP TVS-871 running the latest firmware 2.4.2.1312 and Roon runs perfectly on it and every time I have updated the QNAP. I have not had any issues with Roon, I would suggest the issue is more Sooloos than QNAP.

However as has been said Meridian state the NAS should be dedicated to Sooloos and one of the first actions when setting the NAS up as per Meridians instructions is to disable automatic firmware updates, not sure they say to never update though?
