I use the TV speakers, and I'm experiencing audio skipping only inside Roku apps and then ROKU menus. The issue does not persist in HDMI modes. The issue is almost always present, with some reboots fixing the issue. I am on Roku 8.1.0 build #4139 TCL TV Model 55US57-W.
I saw the issue with the other streaming players and I haven't seen anything about this model TV. It's obviously the software, and not the hardware as the system works in other video modes. Any tips? There was no updates available.
