Old av receiver to HDMI tv

Solution
Without makes and model numbers can't give you a specific answer.
If your TV has a digital audio output and the receiver doesn't have any digital inputs you need a DAC like this one

Other options are to connect your sources to the TV with HDMI and connect separate audio connections from each source to the receiver.
If your sources are HDMI out only then and HDMI switch with audio extraction will help.
