Issue: the main fan sound in the cab repeatedly cuts in/out when multiple audio streams are playing at the time. This is at it's worst with both windscreen wipers enabled and when applying the brakes. To recreate: run any journey / scenario etc and switch on both wipers. When applying the brake or sounding the horn, the fan sound cuts out. When driving down hill with the vacuum brake permanently on, the fan sound cuts out every time the wiper sound 'clicks'.
