Hi @raysong 

The Arc muting when your TV is off is not something it’s doing on it’s own - it’s being told to do so by the TV via HDMI-CEC commands. When things go wrong, it can be an issue with the CEC network the TV creates between the HDMI-connected devices. It should be easy enough to resolve, however - please unplug your TV from power for a few minutes. This will restart the TV software in a way that standby will not.

I hope this helps.
