Hello - I am having the issue above after setting up a new Spectrum remote UR5U-8780L with my Sonos Playbar.
I used the Sonos app to setup remote control, and everything is working great. However, when I adjust the volume +/- or mute using the Spectrum remote, the volume adjusts but I also get the message “not available” from the Samsung TV. I want to get rid of that message.
This post from a few years ago describes the issue perfectly and provides a link to FAQ to fix, but the link no longer works - can the correct FAQ link please be provided?
”Hello, The message is popping up because the TV is still receiving the IR signal from your remote to adjust the volume, but the speakers are disabled so it's giving an error message of sorts. There are ways to bypass this on-screen message by using a cable/satellite TV remote or a third-party TV remote programmed to adjust just the PLAYBAR's volume but not the televisions. I'd suggest taking a look at the following FAQs to see if you have an available remote you can prhttps://sonos.custhelp.com/app/answers/detail/a_id/2083”
