I'm so happy Roku added a night listening mode to their TVs with Roku built in (previously I only saw it on the set top Roku boxes).

@Brainclean is this an #audio-only output mode or just room surveillance?
The latter one would be a #WontBuy!
@kkarhan As far as I can tell, it just reduces the dynamic range of the audio to have less variance, so you can increase the volume without a loud sound waking up the neighbors.
AFAIK the TCL Roku TVs don't come with microphones standard.
