Default Galaxy Tab Pro 8.4 Speaker Noise When Volume Muted

I'm just making this thread in the hope that this is a fixable problem, so here goes...

If I mute the tablet by lowering the volume until it is off and then play music or a youtube video, or indeed anything else that would normally result in sound through the speakers, I can hear a quiet noise that sounds a little bit like an old 56k modem trying to connect, sort of squelchy chirps and tweets.

I can recreate this every time, so I'm wondering if anyone else is having this problem and if so, did you find a workaround or a fix? I found a thread on another forum where others were having the same problems here:

It's easy to test, just go to youtube via your browser or the android app and play a video that has sound with your volume as low as it'll go.

Thanks!
