When I use Alexa voice control to play music on The ARC (using Amazon music ) it never plays hd music.
Only when I use Amazon music (which I keep having to reauthorize via delete and adding again) through the Sonos app does the hd kick in.
Basically using Alexa on the arc won't play high quality music.
Why is that? Is there a fix? Is it a known issue cos it sure as hell bugs me.
