So, one of the biggest problems I'm having at the moment is with sound. If I switch to an external camera I rightfully hear the, much louder, external soundset but often when I switch back into the cab that soundset keeps playing. It's frustrating when that happens because I can't seem to undo it. I can be halfway up Sand Patch and have it happen, so I'm faced with finishing the service with the sound at a much louder level than it should be at. Obviously I can just adjust the volume of my headset, but I shouldn't have to. I'm often left with choice of either risking enacting the bug, or running the entire length of the route without using the external cameras once, which isn't fun. So far I've had this happen on the SD-40, HST, Class 166 and the Class 66.
I also experience this bug -- it happens often randomly when switching between views; prevalent is definitely going from view '3' to view '1' is that it always seems to continue playing the sound without the cab filter.
