I have done this a thousand times because every time I do it, it works...for awhile. Then it gradually becomes out of sync again, and when no one can stand it anymore, I "refresh" the changes (change it to something else and then change it back) and it's better...for awhile. How does Roku not have some explanation as to why this keeps happening and some permanent fix solution for it? I love Roku for everything else, but this. is. annoying.
I searched all over the Internet and all over these message boards and tried everything. The only thing that worked was to do a factory reset on my plasma TV. I have an old Samsung plasma TV and using an old Bose lifestyle 3500 as a receiver. I plugged in the Roku express stick plus into the HDMI port of the plasma TV and ran an optical cable from the optical out port on the TV to the Bose receiver.
I have the exact same express stick plugged into my Yamaha TSR 6750 receiver which runs to my old LED 6500 series Samsung TV in another location.
both locations originally worked fine when I installed the express sticks sometime after Christmas. Both locations had problems with the audio video sync. now that I have done the update, I believe that one of Roku‘s updates messed up the A/V sync.
I hope the next roku daily update does not mess with my solution. I finally get to enjoy YouTube and Netflix again at least at my plasma TV location. I am going to do the factory reset on the other express stick later.
I have Roku Ultras and sticks. Seems as though the only audio lag issues is from 1 of the ultras. The best easiest way I found to fix problem is to pull the power cord from the Roku unit, then plug it back in. Funny that 1 ultra has the problem and the other does not, even though both are used on LG OLED TVs. The problem also does not happen as often as it has in the past.
Just completed the factory reset on my Roku streaming stick + that is plugged into my Yamaha TSR 6750 receiver. The video is still ahead of the audio on Netflix, YouTube and I’m sure all the other apps. The only difference between this set up and my upstairs plasma TV set up is that upstairs I have an optical audio connection from my TV to the Bose receiver and the Roku is plugged directly into the TV.
I have ordered an optical cable which I will run from my TV to my receiver and then I will plug my Roku directly into the back of my TV. I am hoping that solves the issue on my downstairs set up.
