A:AnswerI have a bluetooth soundbar attached to mine, but you need to purchase a bluetooth transmitter and make sure it can either use a Toslink digital audio cable or purchase a digital to analog converter as this TV does not have analog audio outputs as currently advertised on Best Buy. So it is possible but maybe easier to just purchased a different TV with analog outputs and get a BT transmitter.
A:AnswerI haven't but I believe you can cause it has two HDMI ports and I have connected my son Nintendo Switch to it via HDMI cable so you shouldn't have a problem and gaming looks awesome on it.
