A bit of a long shot but I'm wondering if anyone has a picture or remembers the the default sound setting please. I've messed about too much and I need to start again. I have master, player and engine on 100 but it's the others. Cheers
In C:\Users\abc\Documents\My Games\SimBin\RaceRoom Racing Experience\UserData there's a file called audio_options.xml. Try moving the one that's there to another directory (as backup) and start the game, the audio options should be reset to default. After taking a screenshot of the default settings, move your file back into that folder (or just work with the new one and adjust to your liking).
