HDMI Powered Audio Extractor Bluetooth Transmitter
(1/1)
dellsam34:
This is probably a pipe dream but I need to monitor audio from a HDMI out using my Sony Bluetooth headphones, Is there really a compact size HDMI audio extractor built in audio Bluetooth transmitter that plugs into a HDMI output socket and get powered by it? I've seen bigger HDMI audio extractors that require a separate power source and a HDMI cable, but my quest is to find one like in the attached illustration (taken from a video transmitter stock image) that can be plugged in and powered by the HDMI connector's 5V pin?
NiHaoMike:
You could cobble one together out of a cheap HDMI to VGA+audio adapter and a Bluetooth audio transmitter module.

I guess it could be made from DIY PCB kits, I know there are HDMI to SPDIF audio extractors tiny PCB's and there are SPDIF Bluetooth transmitters tiny PCBs, It's just a matter of connecting both SPDIF ends together and have them both powered from the HDMI 5V pin which can handles up to 300mA, The casing can be 3D printed at home. It's worth investigating.
