Okay, to make the mystery even more complex - after my game crashed I changed the location of my sound effect on my track to literally be the default start position in the pits so I didn't have to keep driving to find it. Restart, game doesn't crash everything is fine, but no cockpit sound (the sound position had changed though and this is verified with the f7 camera. Then I load back up Goodwood - and now can't hear the announcer at the start line anymore, despite still running v0.8.2068.36126 So I think my game crash may have automatically changed an option or something in CM which has now stopped the sound on Goodwood from working again??? I went to double check it hadn't auto updated or something when I restarted it and it's still on the older version. So to summarize, now i'm back to square one, with both tracks not having cockpit audio, despite running an older version of CM.
