7.5.1 introduced massive (460ms) audio sync issues with Plex - the primary use for this device in my household

I have a 4 year old Roku 3 and it does not have the sync issue

Wish I'd seen that it frequently has audio sync issues

Yes, that resolves the voice sync issue but misses the point entirely

As MANY other people have posted, there is a terrible audio syncing issue with this device.

As others have mentioned, and Roku has confirmed but refuses to do anything to resolve it, there is a sync issue which gives constant HDCP 2.2 error messages when using certain apps

Would give 5 stars if not for voice sync issues

The Roku app still has sync issues

I had audio/video sync issues with this on multiple channels

I have never kept a Roku longer than a year; due to laggyness in the interface, and audio sync issues in Hulu and Netflix
