Hello, I also have the same issue since season 2 started, and same as others here I also have a laptop and a Realtek output device. When I log into the game I have no sound. The only workaround that works every time is as follows: disable and re-enable your output device in sound settings (disable from “sound properties” but re-enable from “manage sound devices”), then go to sound options in the game (no need to touch anything there) and sound will magically come back. This needs to be done every time you launch the game, and with the game running. It works, but useless to say it’s really annoying, please fix it.
