To connect to the Windows PC or the TV, I use the HomeSpot BA210 v2 Auracast transmitter. Both my TV and PC have Bluetooth, but are three to four years old and will not connect to the HAs except through the Homespot. I find the Homespot preferable to the FlooGoo USB dongle. The dongle only works with your PC because it is limited to a USB connection, while the Homespot works with the TV because it has a variety of connections. Even though your TV has a USB connection on the back it most likely is for audio input only and does not provide the needed audio output. See Auracast transmitter tests - #17 by JG1 for insight into the Homespot and FlooGoo solutions.
