I have a sound bar which I typically leave tuned to Classic FM on TuneIn. When done for the day I stop the stream with the power button on the bar. When I press the button again, it starts. I have an IR remote control from an old TV and have it linked to the Sonos sound bar. When the stream is streaming, I can turn the volume up and down at will with the remote. When the stream is stopped, I get weird IR behaviour. Volume down works, but volume up does not. I say either both should work or neither. Anyone else frustrated by this anomaly?

NB This is related to an old topic - see link below. I was frustrated big time by that. They seem to have half fixed it.
