Can't get sound to come from speakers with tv only the radio

You didn't give the brand and model of your TV, and I can't try to find a manual and see what kind of AV connections it has available. So here's some general information.

Many TV sets only have input jacks for external sources like DVD players or cable boxes. When you select an external source, or use the set's internal tuner for TV programming, the video and audio play through the TV. The trouble is that if the set has no audio output jacks, there's no way to get a sound signal out. The TV accepts only inputs

When the TV is part of a home theater system, most people use it just as a video monitor. All AV sources connect to the receiver, and audio is sent from there to the speakers. A video output from the receiver goes to the TV so you can see the picture, and the TV's speakers aren't used. If you have a cable box, FiOS set-top box or satellite receiver for your TV channels, they connect to the receiver too, since they're just another external source.

This doesn't work if you rely on the TV's internal tuner for TV channels, though. This might be the case, for instance, if you have a cable system where a converter box isn't required and your cable connects right to the TV. When you're watching regular TV, then, the sound comes through the set's internal speakers. If there's no audio output available on your TV, that's your only option.

As I said earlier, many TV's have only audio inputs. But some have audio output jacks as well, so the sound has a way out. If yours does, you can connect them to one of the inputs on the home theater receiver. Then when you select that input you'll get the TV sound through the speakers connected to the receiver. Depending on the design of the TV, you may need to leave the TV volume turned up. Some sets have outputs that are follow the TV's volume setting. On others, the output is an independent fixed level. Then you can turn the TV volume down and use just the receiver's speakers if you want.

Check the connections available on your TV and look for a set of "audio out" jacks. Your TV's owner's manual should have a section explaining how to connect it in different ways. If you need a copy, most manufacturers have manuals for download on their website.

Good luck with your sound, and thanks for using Fixya!
