Sound fades in FSX when ATC speaks, then returns 20s later
We have a strange sound issue with the Majestic Dash 8, which seems to have appeared since a recent Windows 10 update.
When the Dash 8 loads, the aircraft sound is fine, as expected. However, as soon as ATC speaks, the sound drops down to a low background level. Once ATC has finished speaking, we have to wait 20 seconds for the aircraft sounds to return to their normal level.
Everything in the FSX sound settings as the same as it always has been - default sound device etc.
We've also tried reinstalling, but the issue remains.
Any suggestions, please?
Thanks in advance,
