No sound from some speakers

  Dave R 09:16 28 Dec 05

I have a Creative S.B. Audigy 2ZS soundcard and 7.1 speakers. I can only get sound when I play a music c.d from the three front speakers. The creative system is set up for my 7.1 speaker system. If I do a speaker test in the creative speaker set up then I get noise from all speakers. All speaker connections have been checked. Any advise would be appreciated.

What happens if you play a DVD which has been Dolby Digitally encoded with 5.1 sound?

An ordinary 2-channel stereo music CD won't have any information on it to supply additional speakers, although your amplifier may 'mix' its two channels to feed a centre front speaker.

thanks for the reply. I tried a DVD and 5.1 sound and 7.1 sound and the only speakers that work are the front ones and the front centre speaker. The DVD sound is coming out of the same speakers that a CD playing on the system is. When I first had the computer all the speakers would work when playing a music CD.

Thanks for the post I have check control panel - sounds... and the speaker set up is correct.

The fault has now been traced to the Surround Sound Mixer. The default setting for the wave and the midi synth were both set to the max level (100%) When both these settings were reduced to 50% all the speakers on the system worked.
