I’m having the same issue.... I’m just connected to my tv audio.... sometimes changing from audio detect to stereo worked sometimes not.... I’ve factory reset it once or twice but tired of resetting all my apps!!
ive unplugged, replugged.... I’m about ready to return.... my Roku Xp never did this.
imdecided to upgrade for no reason,.. about ready to plug old one back in and return.... 7 days new and reset it at least once a day.... fed up!!!!!
Thank you! Installed the Vizio 5.1 Soundbar with sub and two satellite speakers last week and then the "lip lag" started a few days later. Doing the above fixed the issue. Thank you for the quick and to-the-point solution.
For MY setup, at least, the problem definitely is within the Roku’s inability to handle automatic refresh rate changes properly, especially (but not exclusively) when program source involves changing servers. Possibly Roku hardware &/or OS software is simply unable to accomplish it quickly enough? Who knows. But this business of Roku “support” person here constantly asking everyone to report on the exact same and now seemingly uselessly repetitive variables is just plain nuts and a waste of us consumers’ time.
At any rate, I have found the only work-around that seems to work consistently - at least for me, on Roku STB units (the stand-alone units, not Roku TVs as I do not have such tv) - is to go into Settings -> System -> Advanced system settings and be sure that “Auto-adjust display refresh rate” is DISABLED.
Obviously this is no “fix” and merely a less-than-desirable work-around, and certainly for other folks any and ALL of the previously-posted work-arounds may be necessary in addition to this one of mine, but this one is the only one that works consistently with MY setup (Roku Ultra to Panasonic 1080 Plasma w/multiple refresh rate capability).
Up until recently I recommended Roku to EVERYONE. But until this SERIOUS issue gets TRULY fixed I sadly find myself having to recommend the relevant Amazon products.
