I am looking to connect my amp AIYIMA A07 to my TV Hisense 55hg8 h8g. Only problem is that the TV only has a output audio port using digital audio out with a optical cable. The amp only takes rca in.

While wireless audio is likely our future, cables will almost certainly remain part of our audio and home cinema set-ups for years to come. So it pays to know a thing or two about the different types ...

There are only two ways to get digital audio between your TV and soundbar, or your TV and receiver, or really between any piece of gear that transmits audio in a home A/V system: HDMI and optical.
