audioEnergy being 0.00003051851

Running into this situation: some clients connecting to the site we built, produce audio but it is inaudible and audioEnergy metric in chrome stats is 0.00003051851, which is curiously, precisely 1/32767. So sounds like the audio is captured as 16-bit (s16le) and is somehow supplied as all-1s, i.e. 0x010001000100…

What can be probable reason for this, what shall i look into? Can it be some Mediasoup setting, or a problem with my constraints?

What do you mean by inaudible?
