Proud R3 Owner

NAT is open but I'll try disabling the firewall at the top. Honestly it happened again last night with QoS disabled along with gaming prioritization disabled - even tried disabling goodput but was going out of sync after the ads. I'm thinking it might be the TV itself but I'll try disabling the firewall first. Also I'm back on the 3.0 beta after it went out of sync again. Might not even be router related tbf.

Yes, I have tried disabling gaming prioritization with no success and have left it on and disabled QoS with no success. Only when I disabled both does it stop the audio and video out of sync issue.

Internet speeds are good, about 1200Mbps down 35 Mbps up. This issue happens whether prioritization is active or not.

I've noticed when using the QoS enabled and game prioritization enabled, the audio and video will go out of sync on HULU on my hard wired Roku TV. Right now I'm on the latest firmware but only upgraded from the 3.0 beta because of this issue. Once I disabled QoS and game prioritization the issue goes away. Didn't know if you've come across that issue or not.
