I've been using a Roku soundbar for several months now without issue. However, in the last week I've noticed that the volume level icon constantly appears in the top right hand corner of my screen when I'm not pressing the volume button on the remote.
This seems to happen whenever I open an app and start/change videos. It also happens whenever adverts play mid-stream - for instance, on YouTube or apps like All4 or My5: the volume icon will appear every time a new advert plays, and again when the main programme restarts. Most weirdly, the volume icon keeps appearing in the Netflix app when scrolling through play lists on the home screen (it seems to happen every time a video preview starts to play in the background).
I thought it might be a problem with the remote, but it persists even when I use my iPhone app as a remote. I've tried restarting, reconnecting to TV, but still continues. I've stopped short of resetting to factory settings though.
I am on software version 10.0.0 Build 4177
I'd really appreciate any advice on how to fix this - or at least I want to report this in case it's a software glitch - as it's starting to get a little too distracting and irritating. Many thanks.
