Question about Onkyo HT-S990THX System
I'm having issues with my optical audio inputs. Sometimes they work, sometimes they don't work at all. Sometimes they cut in and out. I have tried different cables, and all three optical inputs. I have also tried using 2 different devices (PC and PS3). Everything was fine until one day the sound kept cutting in and out for no reason. Analog inputs work just fine. Do you have any suggestions?
Make sure the cables are not KINKED in any way or twisted up with any other cables or near any HEAT Source.

U need to reset your parameters.....Goto the System button and then press F5. This will lead you to where you need to press initialize to reset the parameters. Don't worry it wont delete any of your sounds etc. I had the same problems.....u will probably have to do it every-time you turn it back on and off. I think the cause of this is due to it having a previous expansion on it......

SOURCE: Digital Audio Input
On many ht receivers you must enter setup mode and tell it which digital input you are using for each digital source. i.e. you can choose optical for the DVD input and coaxial for CD, and vice versa.

Cat, Splitting an optical output is not recommended. In fact it would require an optical patch bay, which would be overkill. You could use the headphone output on the front of the Denon AVR3805. Because this output is behind a door it might be a cleaner looking set up to use the optical output on the top left looking at the back of the unit. Because those two optical outputs are labeled "optical 3 and 4" they are zone outputs, they should work without having to "map" or patch them internally. The outputs here will be controlled independently as zones from the receiver's remote. The easiest option looks to be the analog "pre output" located in the middle of the back of the receiver. The left-most two rca jacks you want to use are labeled "front" and are white over red. This output will work fine. Control of the volume will be from the headphone unit and not the receiver.
