Yesterday during a radio broadcast from iHeartRadio the volume dropped to about half without me changing anything on the system. Today the problem persists and is impacting numerous stations on iHeartRadio, TuneIn, and Sonos Radio (I have checked multiple stations from each platform). I can turn the volume up to about double the normal level to get back to actual normal volume but this is inconvenient as then you have to change volume settings when you change source (or put the whole house on blast).
Any help? Thanks!
