Noise when powering off radio

[fredpb]

Most of the time, when I power off the radio, a get a loud "farting" noise. Sorry about that. But that is what it sounds like.
Anyone else get this?

Blame it on the dog?

I def. don't get that (on either beta or production units). Just a single soft click.

Does it make a difference if your were streaming off your server or directly off the 'net?
