Vizio’s 32-inch LCD televisions support three options for connecting to surround sound. From best to worst quality, these are: HDMI, optical cable and RCA cable. The sets output signals through any or all of the audio output sockets when a cable is plugged in, so you don’t need to actively select an output socket to use. If you use a surround sound receiver, however, you’ll need to remember to mute the sound on the TV. These televisions also support a virtual surround sound mode using the built-in speakers.
