Hi. I'm thinking of getting digital cable, but I only have an SD TV. It does not have stero sound. Do they make a reverse Y adapter (2 sources to 1 destination adapter) with either a manual or automatically sensing switch?

Basically, I need the opposite of this:

Also, do they make an adapter to convert stero (right + level channel audio into mono audio?

I'm asking because I would prefer not having to use the coax, since we all know composite is one step above coax. And because my TV only has one composite and one mono audio jack. :(

Any suggestions?

Just use a simple y-adapter in a backwards fashion. It will work.
