So is the roku stick worth it if the audio is always cutting out. I’d say no. I’ve tried all the fixes (PCM stereo, reinstalling the app, etc). It’s a design flaw that id be happy to share with anyone. Roku reinvented a dud. No resolution on this thread either.
What model and model number Roku are you using (Settings > System > About will show you)?
I have an older Streaming Stick (3600) and a later Streaming Stick+ (3810) and don't experience this with either one.
