Hi, i bought a LED TV with no audio out. No digital optical output. I have check the back and the manual. My cable company provide a coaxial cable (analog) that i attach directly to the tv. Is there a device i can put between them that will generate an audio output from the coax cable and then pass the original cable tv signal to the Tv? I need the audio output for a wireless headset. Will a rf modulator work? Thanks in advance.
