And restart of MP doesn't resolv the audio problem. Only whole restart of the computer.
Make sure that both tv and movies are using the same audio renderer in MP's config.
Yes, they have. I will do some further tests this evening. (Probably audio is on the digital output instead on HDMI output, I'll check it)
But configured it is right. When not, a whole restart of PC wouldn't bring back audio on movies.
Unless specific audio renderer has issues with S3. Drivers could be having a bug that causes such failure for specific audio renderer.
If restarting of MediaPortal doesn't help it is highly likely that the issue is outside MP.
