My Channels app is set to surround sound because I have a home theater setup and I want the full experience.
Unfortunately, when trying to change volume with my Bluetooth remote on my Nvidia Shield, I get the following "Surround sound enabled. To adjust volume, use your TV’s remote control." When I turn surround sound off in the Channels app, the volume slider with the Bluetooth remote works just fine.
FWIW, with the HDHomeRun app, this is not an issue, I can adjust the volume using the Bluetooth remote regardless of surround sound.
Now, I did some poking around and this seems to be a common question with AndroidTV. Over on the Plex board someone was told to turn pass through off and that resolved the option for them.
Is there something that can be done in the Channels software to accommodate this? The experience is really not great when I have to switch remotes just to change volume and Bluetooth remotes offer the best overall experience.
My Samsung TVs don't have HDMI-CEC so that's probably why this isn't a big deal to everyone but is to me because that would solve this issue. My Samsung is only about 4 years old so it's not ancient or anything.
