snd-ca0106 -- Rear and center speakers are silent

Adrohak · 03-21-2005, 08:19 AM

I just bought a SoundBlaster Live card and Creative Inspire P5800 speakers, set them up, and got sound playing on them, but the center and rear speakers are silent. I have the volume set to 71% on each speaker, and still only hear music from the front two speakers and the subwoofer. What could the problem be?

Thanks in advance.
