After a lot of reading I found this information
That confirms to me that Sq players goes “dumb” under Roon server, so they simply are the endpoint to send music to my audio equipment… All control must be done under compluter or APP into cellphone (my case) but I have also noticed the on/off feature is not working.
I have a Duet (only led colours are revealing so) but Touch is not showing the cover on screen or the V/U meters, which is something I really appreciate, if I am not “touching” the screen. But if I do so, then the Touch is ON after I have used the “off” function in the volume actions available for this specific item/zone on the Roon.
Any idea / help / suggestion?
