I have a Soundblaster Platinum Live card with the IR drive, Midiland 5.1 speakers on a new system:
Abit KT7A mobo with Athlon 1.2 processor. Sound works with line-out on the PCI card, but no sound from the optical out line on the Live Drive with the exception that occasionally I can get test sound from the RR and RL speakers. The optical cable is ok and the speakers test out from the Midiland digital box. Also no sound coming from headphones attached to Live Drive. Are there any other possibilities that can be causing this besides a faulty ribbon cable to the Live Drive, or the Live Drive board itself? Creative Tech Support suggested IRQ conflicts so I moved the PCI
card around a few times and I've tried uninstall
and reinstall more than once. Anyone have any ideas?

Optical cables are very fragile so check the cable in another system. I am assuming you are using a toslink or variation of, such as a mini. Testing of conventional toslink can be done in your audio system if equipped with a digital link from a dvd or cd to your receiver. Mini toslink would be harder to test with out similar equipment, such as a portable mini disk recorder.

Going back to the fragility of the cables, they cannot be bent in any way shape or form. You may leave them in a gentle circle but do not bend at any angle.

Dose your "box" have an indicator that a digital signal is present? Also look at the card to make sure the I/O from the drives are seated properly and in the correct orientation. IN some cases you may even be able to look directly into the optical jack and check to see if there is a light coming from the LED used in the optical out, Don't worry it's not a laser!

My experience is in the audio field where optical cables are a pain, I prefer to use a coaxial wherever possible.

Brent--thanks for your response. Yes, it is toslink. I did check to see if light was coming from the cable and it is, without interruption as I move it around. There is no digital signal indicator, however it does have a little graphic equalizer, which is flat most of the time except when the rear speakers are working. I think I will try the coaxial connectors.

Try as well to see if there is an input select on your box as sometimes the switching has to be set manually.
