Don’t know if this applies to streaming to Devialet Expert only or in generic but in the past my Squeezebox was always streaming. WHen switching back from TV input to Squeezebox there was immediate music. Same goes when turning on the amplifier in the morning.
With Roon I have to grab a phone or ipad first every morning and again when I switch back from TV.
Can streaming be resumed when I select the Roon input again (in my case AIR)?
