When you use a sound bar. Even if you had some lag control you may still hear it.
Fix? Turn off the TV speakers.
I have an older Vizio VO47L tv, with my Directv connected via HDMI 1, my Xbox One on HDMI 2. my Toshiba laptop is HDMI 3. I just purchased the 38 inch Vizio soundbar with woofer, SB3821-C6. I have it connected to the Vizio tv via digital optical cable. Now I have lag between the tv speaker and sound bar, and laptop and tv, and the only way to stop it is to cut the speakers off on the VO47L tv. Is this just the way I have to do it with an older TV? TIA.
