Ambient Airport Traffic Sounds while airborne enroute

I am hearing the sounds of jets taking off etc. while I am flying enroute. I have turned off third party programs but I still hear these sounds. I expect to hear these sounds when on the ground at an airport but not when I am enroute. Any thoughts on the source of these sounds and how I may control them?

This is probably the same issue.

Thank you for your response. Sounds like this may be it. I did search prior to posting but didn’t get this link

This apparently has been corrected in SU9

Chat question - Is there a fix coming for the jet engine sounds in the cockpit that surfaced recently? - Timestamp

Martial - Yes, in the next sim update [Sim Update 9].
