Roku Express: Audio Out of Sync
So I just wanted to update this with the solution I found. Somebody in another thread suggested it- under your Roku settings on your TV, scroll over, then down to "Display Type". If it is set at 1080p, try switching it down to 720p (or depending on your TV, simply choose a lower resolution). This should hopefully fix issues with buffering and audio/video being out of sync.
-----------------------------------------
I have a Roku Express and a Sony Vizio TV (model # E420VO; it's close to 10 years old at this point)
I've been having this issue for as long as I can remember. The two channels/apps that are the worst are Prime and CNN. I'll be watching and everything is fine, but then there will be occasional stuttering and buffering which leads to audio/video being out of sync, sometimes only slightly, but right now I'm watching CNN and it's pretty bad, lagging by several seconds.
I have...
Exited the channel and reloaded... nothing.
Turned off TV. Restarted.. nothing.
Restarted Roku... nothing
Unplugged and reset Roku... nothing
Turned off computer and restarted (in case any games might be affecting bandwidth)... nothing
Unplugged and turned off modem and router and restarted... nothing
Changed audio settings to stereo... nothing
Checked for Roku updates... nothing
I have tried all suggestions given and the audio still goes in/out of sync. Occasionally restarting the app/Roku/modem will help for a short period of time, but then it will return to stuttering/buffering and fall out of sync.
Is there anything else I can do or try? If I buy a newer Roku device, will the problems stop? Maybe mine is just too old? (Have had it a little over 3 years now.) Or maybe getting a new HDMI cable? I don't have this issue so much with other channels/apps. It seems limited, for now anyway, to Prime Video and CNN.
