I thought that Forza had fixed all the bugs in regards to the annoying buzzing sound you get instead of your cars engine sound. I had not experienced it for over a year or more in the B Class Lobbies. Well, it is alive and well in the A Class lobbies! Every time I run the 1966 FF Corvette at any Rio track in A Class Lobbies, I get the buzzing sound. I thought it might be a paint job thing, so removed all liveries, and still get it at that track every time. Any other car at Rio, and it does not happen. Does anyone know why this happens? Is there a place I can submit a "fix it" ticket to Turn 10?
