My sonos roam keeps cutting out whilst listening to the radio. I listen to virgin radio that cuts out every minute for about 5 seconds. This also happens on the Global App. 

If you listen to BBC sounds or Spotify, all is fine with no cut outs. I have been in contact with the tech support and sent countless  data back to them as well as  countless resets. I have also contacted my Internet provider and switched the channels for both 5hz and 2.5hz for ones that have no interference.  The firmware of my router was also updated.

I personally think that this is an app issue as switching back and forth between the stations shows that there can be stability on certain ones.

Any ideas?
