New TV With an Unknown Audio Out Jack?

"There are cheap converters that you can buy that will convert HDMI to RCA though."

- Ok thanks, I'll look into that, still would like to know what that jack really is.

The tv doesn't get delivered until Saturday and I want to have the correct cable. I do have a standard Toslink cable with the same termination at both ends. The new tv optical output does not have the same input jack that the Zvox has (standard Toslink). The new tv owner's manual only mentions an optical audio output but not the type. There is a different type of male connector called a Mini-Toslink, very similar to a 1/8" head phone plug.  Mini-Toslink

Could be, like I said above it gets delivered Saturday.

I found out from someone at the AV Forum that it is a newer version of a standard Toslink that allows insertion from 4 angles instead of just one as the old ones do giving more flexibility for different cable routes. Thanks all for your input on this!

It turns out this is a standard Toslink panel connector that can be used in 4 different directions. All hooked up and works fine. Thanks again for all your help!
