Additional information

Here's is the audio_settings dictionary output for my TV. Even when the tv is muted there still is no mute key.

{'tv_speakers': 'Auto', 'volume_control_display': 'Off', 'surround_sound': 'Off', 'volume_leveling': 'On', 'balance': 0, 'lip_sync': 1, 'digital_audio_out': 'Auto', 'analog_audio_out': 'Fixed', 'volume': 63}

Hey there @raman325, mind taking a look at this issue as its been labeled with a integration (vizio) you are listed as a codeowner for? Thanks!

@zachowj thanks for sharing the audio_settings dictionary. It appears some, but not all, TVs have this mute property. I will push a fix out soon.

@zachowj this should get released as part of 0.109.2
