Not sure if this is a Zwift issue, a Windows issue, or just my hardware issue…but I have a bit of a loose headphones connector on my laptop. If my headphone jack loses the connection to the computer and drops out, I lose the headphones sound altogether when I plug them back in. When I plug the headphones back in, I get nothing. I have to exit the game and restart. I can still hear system sounds through the headphones, just nothing in Zwift.
Not a big deal at the beginning but it would be a real bummer to be into a long ride like the Thanksgiving Metric, lose sound and have to start over.
