I use my Sonos Amp as a Home Cinema amplifier and it was working very well: as soon as I switched on my TV, Sonos Amp switched on and amplified the sound brought by HDMI ARC.
Since I created an account, downloaded Sonos S2 and configured my Sonos Amp, I must open S2 application and choose TV in order for the sound to be amplified by my Amp. That wasn’t the case before.
Is it possible to make Sonos Amp amplify the TV sound by default ? (otherwise I will factory-reset it and stop using Sonos S2)
