Audio signal suddenly change from headset to monitor.

[ImRocketMan]

Sorry if this is wrong section.
From a few days, I have a weird problem with my pc.
Only when I play a game, suddenly the audio passes from headset (connected via green&pink cables) to monitor (connected via HDMI), just for a few seconds, then goes back to headset.
I usually make this manually with the Windows volume mixer. I don't like the pc makes it randomly without my decision

I thought was an headset cable problem, but it happens only when I play. Any idea?

Is it only one game or does it do this on every game you play?

Did you try a System Restore to a prior date? http://www.sevenforums.com/tutorials/700-system-restore.html

It happens in every game. Seems I haven't a restore point.
