I have a Roku3 model 4200X. Lately I have noticed that when using the Netflix app the audio is out of sync with the video and it bothers me. I tried power cycling the Roku with no effect. I deleted and re-installed the Netflix app with no effect. I tried adjusting the audio setting on my Vizio TV with no effect. It has a setting for adjusting audio sync and but doesn't help. I tried changing the audio mode in the Roku settings with no effect. Normally I have my TV connected to a pair of powered computer speakers. I tried disconnecting those speakers and using the TV's built in speakers but I get the same audio sync issue either way. I don't have this issue with either the Hulu or Amazon Prime apps, only with Netflix. I also don't have the issue when I watch OTA channels on this TV.
I am at wits end. Does anyone have any suggestions short of either unsubscribing from Netflix or throwing my Roku box i;n the trash? Thanks.
