SoundBeam custom states not updating

I've added a SoundBeam to my Sonos System (added as a SoundBar) which all appears to be working OK apart from the following error every 17 mins or so..

Code: Select all

Custom states work briefly after I restart the plugin but then stop updating. I'm not running any playlists, just using it as a dumb soundbar at the moment. All I really need is the Volume state as I'm using this to control the volume of another non-sonos amplifier.
Any thoughts..?

Colin - not noticed that on mine, I will keep an eye out for it.
