How do I switch off - weird dialogue box about audio that pops up radomly

[fatbloke]

Hopefully you can see the weird dialogue box (centre screen) that keep popping up at random intervals. It doesn't say up for long, a few seconds then it fades away.

I'm sure it's harmless, but damn it's annoying...

I have no idea where to look for some sort of switch/setting, despite having looked for the last hour or so...

I see a similar dialogue box when my pc connects to my bluetooth audio receiver. So I think the dialog means that a new connection is made with your build in audio card.
So I would go to settings-hardware-multimedia-audio and video and search there for strange things.

Ok tvm, I'll go and look there now

found the suggested section, about the only thing I can see is that the analogue device was listed at the top above the digital source, so I've changed them round and will have to wait and see if it appears again...

TVM for the guidance so far

So, done the weekly updates this morning and that weird dialogue box has re-appeared. I've checked the settings and it's still got the digital one listed first, so the same as when I changed it before which "seemed" to solve the issue - obviously it didn't.

Hence does anyone have any idea how to sort this out so that it doesn't appear at all...very confusing/annoying

Now the damn annoying dialogue box is showing on screen again...

Still completely stumped. It's a notification of some sort, so as with all of those, I "should" be able to switch it off some how, but where to look for the appropriate setting etc, is the ? (I think)...
