When I connect my TV to my cable box with a HDMI cable, there is no sound. How do I fix this?
Check the Advanced Settings of your TV for the HDMI setting. Ensure it's set to Digital and not Composite/Video.
If you've exhausted everything, exchange the box. It could be just a defective HDMI port.
I looked at those tips. They don't apply to my situation. The sound works fine if I connect the cable box using composite video cables and audio cables. Sound does not work if I use HDMI. I want to use HDMI for the cable box because my DVD player does not support HDMI, and so I need to use the composite inputs on the TV for that.
It's a brand-new HDMI cable. I don't have any other device that uses HDMI.
I don't entirely understand the question. I plug the HDMI cable into the only HDMI port on the cable box. I plug it into HDMI1 on the TV and then configure the TV to treat that as the cable box input. I get a picture from the cable box but no sound.

Audio settings for what? The TV does not have a setting for this. Presumably, it is covered by setting the input to HDMI. The "sound" settings on the TV do not relate to the input source, just things related to sound quality. I've gone through the settings on the cable box, and there is nothing to change the output channel.
