Taranis plus - speaker buzz while switched off

Hi all, i've got a strange problem with my Taranis plus. While switched off there is a buzzing noise coming out of the speakers. It is intermittent, ie sometimes it starts as soon as i switch off the transmitter. other times i can leave it overnight and it is buzzing in the morning.

When switched on this noise goes away (replaced by the faint buzz of the interference from the transmitter module).

I've tried different batteries, removing the SD card, factory reset the EPROM, flashing to the latest firmware (2.1.7). Nothing has made it go away.

Here is a video of what i could capture https://goo.gl/photos/nqA7qGRx9Actiouo8.

This is a stock taranis plus. I have not opened it or modified the hardware in any way. and it was fine for the first 2 months. only just started making this noise. Just got home after a morning flying and noticed the noise.

Does anyone have any idea what the issue could be? Any ideas would be much appreciated.

Cheers, Stephen

It's obviously snoring!

Never heard about such an issue. Could be some defect with the power circuit...

May be a return for warranty is needed ?

That's what i was thinking. A power issue that i don't want to get worse while flying.

Cheers
