I am trying to connect headphones but my TV has a broken digital audio output port. I have a TV with a TIVO mini on a MOCA network. TV and mini are connected via HDMI. When I try the digital cable connection direct to the TIVO mini to listen to my TV program all I get is static. I am not sure if this is an incorrect connection or if I have another equipment problem. I am using a converter between my wireless headphone base (RCA connector) and the TIVO mini.
