Sometimes I need to restart the browser a handful of times to get in-game audio working. When I go to YouTube for example, the videos play with sound. Then I load up a game and complete silence.
Given the loading times, it's really frustrating to waste 15 minutes just before I can start playing a game.
On the phone, audio comes through but it stutters during cutscenes. It's quite weird.
I'm wired into a Google Fiber connection on the PC and using wifi on the phone (Galaxy S20).
@mathematiker Can you see if running Stadia in an incognito window might make a difference? That could help to rule out certain issues related to installed browser extensions or your browser profile data. Resetting your Chrome settings might also help.
