My 4 series tcl roku TV is out of sync using an android box with HDMI. Some other channels are ok. Its unwatchable at this point and I'm thinking of giving up on the tv. I have tried everything I have found online. I don't have access to changing the volume mode when streaming by pressing * Its not an option. Tanner has suggested that as a fix. I've also tried the remove auto detect and try pcm stereo option. Still no joy. I am wondering if this tv is a dud.
