Swapped DAC from Ayre to Questyle. Roon recognised Questyle no problem. Went into Audio Source and noticed another Questyle listing and enabled that. Questyle source disappeared. Initially only see attempt to find Squeezebox so disabled Squeezebox support in Setup. Then see listing for the two Questyle sources flickering in and out very quickly every 7-8 seconds (I timed it once I got sick of trying to whack a mole trying to disable either one every time it appears for half a second). I managed after a bit of effort to snap a photo of the two Questyle sources - shows they are both unnamed and stuck on”enabling”. I did try to name the sources but every time I got into the name box, Roon shuts down and throws me out. Can’t think anything else I can do to access the Questyle DAC - did try switching the Antipodes on and off.
Thanks Rebeka. Tried what you suggested. The flickering is gone but there is no listing for the Questyle DAC. I tried both USB port on the Antipodes, tried disconnecting and connecting in different sequences, all to no avail… I connected back the Ayre DAC and it popped back, no problem.
Success! Disconnected both units and waited a loooong time before reconnecting. The two Questyle listing popped up and I enabled just one. It stayed on with no funny business this time.
