For about 2 months now, opening Zwift mutes all sounds on Windows (every application). A Windows restart is required to get sounds to be working again, until Zwift is opened again.
When launching Zwift, just when getting to the pairing screen the system sounds get a bit muffled then vanish after 2-3 seconds.
This computer doesn’t have any OS automatic update enabled. Only update was Zwift.
Manually updated sound and Nvidia drivers and tried the most common troubleshooting steps to be found on the web. Didn’t solve the issue.
OS: Windows 8.1 64-bit
Audio: Realtek High Definition Audio, latest drivers from Realtek 220.127.116.1186
