Median has been working fine until today. Still loads fine, but there's no sound of any kind. Sound is fine in other games.
Avast ran a virus scan this morning, could be related to that, although there's nothing in the Avast log files.
There's an error message at the end of the directSound log file:
"Failed to create a mastering voice
The new instance of IDirectSound didn't successfully initialize"
Any suggestions?
