ALT TAB Sound problem?

[Kip336]

I have a bit of a problem when I alt tab that I can't seem to fix:

When I alt tab, and reopen the game, the sound from the station i was in before I alt tabbed bleeds through.

example: I'm on the bridge in a storm - lots of sound. I alt tab, return to the game and go to the hydrophone station, the game will still be playing the rainstorm-from-the-bridge sounds at it's usual volume, making using the hydrophone manually impossible.

This happens with every station, and even when I pause the game before hand.

Does anyone have experience with this?
I've done googling already, but I only come across issues where there is no sound at all after alt tabbing.
