Firstly you can't install any drivers in a HDR1000S. It can only use the built in drivers for a usb mass storage device. You however use the usb port to power/charge a portable Bluetooth transmitter like this one.
To supply the audio you need to provide this either from the TV which may have audio out via Red/White RCA phono sockets or from a scart socket using a scart adaptor or from the hdr1000S rca phono outputs.
Once you have the transmitter source set up, you should be able to use any Bluetooth speakers to transmit to.
