Did a short flight today and noticed that while on the ground the sound would cut out every two seconds or so for about 10 seconds. When ATC started talking, the airplane's sound would stop, too.

Anyone else had this problem?

my sound stops after a few minutes of flight.

A latency issue with the audio device on the bus perhaps? Are you using the Nvidia audio or a different device?

Perhaps worth putting in a Zendesk ticket...
