I noticed there is no app for Qobuz, the music streaming service. Is there a way to listen to Qobuz off of another device (Android or PC) by connecting to the TV that has the Roku unit attached to it.
You can connect a PC/laptop to any open HDMI port in either a home theater receiver or directly to your TV via an HDMI port. This way you won't have to go through Roku to listen to Qobuz, just use the Qobuz app from your PC/laptop. You could then use the TV or receiver remote to control the volume.
This would be great
