So an update is I'm just going simple and using an HDMI audio extractor to a bluetooth transmitter. Not quite as clean as I was looking for but it'll do the trick. Would still appreciate any ideas.
Hey so I'm designing a case and am hoping to mount the case directly onto a wall outlet. I can't seem to find any products that would allow this. Basically I would need to make the power supply prongs stationary to the case.
I have a surround sound system which is broadcasting a signal to a wireless subwoofer. I would like to intercept this signal with a raspberry pi so that I can broadcast it over bluetooth. I can't find too much documentation on the frequency but I was thinking a an fm-receiver would work.
