Tidal MQA: I've lost my purple light

[fab_aut (Fabrizio)]

Hi everyone, I’ve Roon server running on a NUC (Ubuntu). It worked perfectly with my Bluesound Powernode 2i and I was able, till yesterday, to play every MQA album with a beautiful purple light.
Yesterday I suddenly saw a message saying something like this "Roon has lost control of audio device” and suddenly the light went blue.

This is my path

Is this a bad sign? What can I do in order to get the purple light again in every step of the path?

Thanks and sorry for my english.

All is well here, Roon is reporting “Enhanced”, as your DAC is reporting that it is decoding MQA.

Hi, thanks. But why I’ve been getting purple light, since the very first day, in every step, and now I’m getting some blue? I believe it’s because of that message stating "Roon has lost control of audio device”…

Could this be the reason?

• The MQA ‘Studio’ (blue light) gives confirmation directly from mastering engineers, producers or artists to their listeners. MQA Studio authenticates that the sound you are hearing is exactly as played in the studio when the music was completed and, by implication, that this is also the definitive version of the recording at that point in time.
• A second level, ‘MQA’ (green light) is available to indicate that although the stream is genuine, provenance may be uncertain or that it is not yet the final release.

It would not be accurate to refer to the output of a data-lossy codecs like MQA as bit-perfect.

See also the example from this thread:

Signal path for MQA

Since you appear to be using an MQA capable DAC when you play MQA content Roon does its part and unfolds the content and sends it on to your DAC to render it. Roon does not “think” it knows what your DAC is doing, it “knows” that your DAC is doing the required MQA rendering. When Roon unfolds MQA content and sends it to a DAC that is NOT MQA capable it also “knows” that MQA rendering will NOT be done so it does not show it. Take this MQA album: [CSN%20Album] When played to an MQA capable D…

Ok. So I mistakenly thought that “all purple” light is the best option?

And why the message that “Roon has lost…”?

Fabrizio, ignoring all of those who just post to have a go at MQA, what you are presently seeing is correct. If you were only seeing purple lights before, either the Powernode wasn’t processing MQA correctly or reporting back to Roon correctly. Do not read too much into the “lost control” message. It is almost certainly coincidental.

I’ve encountered the issue. Check to see if turning off exclusive mode option in the devices menu of roon. If you try to change adapter settings outside of roon, ie.via Windows sound properties.while roon is playing, you will get that error message. Hope this helps!
