Sound missing from GSX ground vehicles

[Jetsetter]

Now and again I have to go to go into GSX settings and reinstate my sound setting as it has reverted to 'no audio' for some reason.

Why is that please.

It might have reverted to No Audio if, because of a problem with your audio card driver, GSX wasn't able the initialize the audio card so, it reverts to using no audio device.

OK thanks, although my audio card driver is up to date.

Fact that is up to date, doesn't automatically mean it can't have problems or bugs. It should go away if you restart Windows (and of course, select the correct audio device and save the setting).
