I wanted to further explain my original post, way back in the thread. The Tidal application and it’s settings have nothing to do with Roon or playing music in Roon, they are only for playing music back IN Tidal. So to avoid confusion, I am not going to talk about the Tidal application and only talk about Roon.
First I want to make sure you understand the current state of MQA playback.
- You have no MQA DAC
The only way to unfold MQA is through a desktop application. Tidal desktop and Adravanna are two options. These softwares will do the 1st MQA unfold and then send it to your non-MQA DAC.
- You have an MQA Renderer
MQA renderers are a special class of MQA DAC that cannot do the full unfold themselves because they are underpowered. However, that CAN do the 2nd unfold. The Dragonfly DAC is an example. For them to work, you need to send them the output of some software which can do the 1st unfold. (So the output from #1 above).
- You have a FULL MQA DAC
To use a fully capable MQA DAC is different. To get the best audio in this case, the software should NOT DO ANY unfolding and should send the audio stream untouched to the DAC so the DAC can do it all (Both the first and 2nd unfold). If the software does the first unfold, the DAC may still be able to renderer it.
Now, currently, Roon does not do any software unfolding. That will change in the future, but, at the moment, Roon does not. So, Roon cannot do options 1 and 2 above. It can do option 3, send an unaltered audio stream to an MQA DAC.
So there is currently no setting in any application that will send an unfolded MQA stream from Roon to your DAC. If you want to use MQA you, at this time, must use the desktop Tidal application.
Now, I will comment about Tidal and its applications. Tidal apps are for the device they are running on, they do not control playback on other devices. So, the Tidal app on the iPad is ONLY for Tidal playback on that iPad, it has no effect on playing Tidal back on any other device. That being said, you will not find the Tidal MQA controls on the iPad app because Tidal does NOT stream MQA to iPads, or really any mobile devices, ONLY to desktops.
