While many home theater systems have USB ports, they (TVs, surround sound receiver, etc.) are not able to support our Bluetooth adapter. Unlike computers, Bluetooth driver can't be installed in these devices. This is the same for automotive systems (car stereos / receivers).
You may consider using our Saturn pro (Click here to buy) and Priva II (Click here to buy) to add Bluetooth for your TV. But please note that both Saturn pro and Priva II are for analog audio transmission.
