I have a Sony SRS-X3 portable speaker with Bluetooth capabilities. I wanted to be able to pair it with my TVs. I have a Samsung and Vizio TV neither have Bluetooth but do have USB ports so i bought a Bluetooth 4.0 transmitter(Asus BT400). I plugged the dongle into my TV and had the speaker search for it but they never connected. i looked at the menu on the TV under audio settings but found nothing about the adapter. Any ideas?
