Signal path query

Where can I read about the different colours Roon use (blue, green etc,)?

Can anyone explain what happens here (see picture) when streaming through my SB Touch:

You can read about the Signal Path here.

your SB Touch cant support 192khz/16bit, but it can do 96khz/16bit – so the green dot item is a downsampling being done to make it work. The 2 bit depth conversions are because the best quality downsampler is run at high resolution.

If you install the EDO option on the Touch you can get higher resolution. 192/24 if I remember correctly.

That would be my memory of it also!

Amazing ecosystem the LMS community.
