You are correct. MP3 audio files and Windows sounds are a stereo (2-channel) source, and will have no discrete center channel information.

Thanks Cody,  I was playing Mp3's and typical "Windows sounds".  I am not sure what 5.1 channel source is but I take it I need something that was recorded in "surround sound" to get some true sound from the front center speaker, Correct?

Thanks Again.

What is the source of the audio you are listening to? Is that source a discrete 5.1-channel source? This must be present for audio to be produced from the center channel speaker.

Also, ensure that all connections between the speakers and the system, as well as the speakers themselves, are seated firmly and correctly.

Ok, I understand.

Thanks Cody!!
