Without the model numbers I can't be specific,
HDMI carries audio and video so you don't usually need two connections. Check the input set up menu of the receiver and assign both to the HDMI. Some early receivers did not do audio through HDMI so you might need to assign the coax input for audio and HDMI for video.
I have seen an older HK receiver where that could not be done (might have been broken) so the HDMI was connected directly to the TV for video and the coax for audio.
