A:AnswerThe controls and/or setting on this sound system are to simple for anything like that. There is probably an adjustment in your tv sound setting to speed up or slow down the audio to sync up with the Polk.
A:AnswerI cannot answer your question because I use mine with my smart phone and Bluetooth to play music. I do not yet have a smart TV It comes with a connection for HDMI to a TV I believe. If the TV has an extra HDMI it should work or if it uses Bluetooth it will definitely work.
A:AnswerNot sure about your setup. I use the HDMI cable connected to the HDMI ARC on my TV and the TV remote controls the sound bar no setup needed. The sound bar powers on and off with the TV and the TV remote controls the volume and mute on the sound bar.
A:AnswerIt comes with an HDMI(arc) cable
Your tv should have an HDMI(arc) port on back of tv with all other HDMI ports. It will be clearly labeled HDMI(arc)
Also the sound bar comes with an optic cable as well if tv is not equipped with HDMI(arc) port.
Great mini sound bar I love mine.
Hope this helps.
