I have a 6 speaker home theater system.

However the middle 2 speakers have no sound.

I checked the voltages.

0 volts when a movie is playing versus .22 Vdc when movie is not playing.

Does that help at all?

Thanks,
Andy

Why don\'t you supply us with the brand name and model number of the
speakers? Of the whole system as a matter of fact. That would be a big
help. And did you measure the voltage at the source? And why did you
use DC? Speakers run an AC. And no, what you posted didn\'t really
help.

Maybe the movie you have has no surround sound recorded.

I thought that the radio would simulate the surround sound if there was none?

It also occurs with other movies.

I\'m presuming these are the rear surround pair.

Means nothing, except charitably maybe that at least the speakers are
connected to something and not floating around in the wind.

(If you had properly wanted to test the speakers are connected, a better
check would have been to disconnect each in turn from the amplifier and
with your meter do a resistance check across the leads. It should
measure whatever ohm figure is printed on the back of the speaker.)

Some surround systems have a test mode, to make a small noise from each
speaker, one at a time. Have you tried this?

There are many surround encoding schemes depending on source. And
special effects from your amplifier, and yeah maybe simulating rear
surround - how are we to know you have correctly turned that function on?

The comments posted by other respondents are entirely valid. You have to
help people to answer you, not imagine they are mind readers. Give
useful information - make/model is a good clue, and go find that manual!

Those speakers do work when listening to the radio.

So, I know the speakers are o.k.

Thanks so much.

The test mode is what I needed.

It sent test tones to each of the 3 pairs of speakers.

Manual said to adjust the volume to be the same.

I had to have my ear close to the speakers to gauge how much to change the volume.
