See if you can follow this..
Note: Windows Vista and Windows 7 can only output audio to one device at a time unless you have special drivers for your hardware!!
I have both the xbox and PS3 set to multi audio out, they will send audio out via both the Analogue outputs and the Digital connectors. I use the analogue connectors to drive the buttkicker via a switch, and the digital optical output to drive the speakers and headset(via a splitter)
VIDEO:
HDMI outputs and optical fibres connect to a AV Digital Switch. so Video from the output goes to the main monitor.
SOUND:
optical surround goes from the AV switch to the splitter. From the splitter sound is fed to the Logitech speakers and my headset. Works great.
The exception here is my PC!
Remember the note above!
I don't use the optical output, Instead I connect the analogue audio (usable by the buttkicker) directly to the amp, splitting a channel on route for the buttkicker output.
When I want headphones + buttkicker on the PC I connect the headphones via the headphone socket on the amp (stereo only) Most driving games on the pc are only stereo!
note - a windows application can only route audio to one device. so if you send audio to your usb you wont hear it on any of the other outputs or your buttkicker!
The only real workaround for this would be to do as I do, or have a headset that uses optical input and an optical output from the PC. Then introduce a splitter into the loop and split the output's (optical) on route to the headphones to a separate toslink amplifier to feed the buttkicker! To much pain for me!
I'm sure this could be simpler, and I'm open to Ideas from our resident Audio Maestro (MR Latte)
I have my own Cave as it were, so the amps work for me. the only issue is on-line gaming when I want to chat.. then I use the headset..
to get the headset to provide mic input on the consoles for online gaming I use a usb cable (came with the headset)to get sound into the PS3 (comes out via optical), With the XBOX you connect a 3.5m stereo connector from the fantec Wheel/controller to the speaker headset controller unit.
Hope this is of some use.
Feel free to ask Questions.
Note this doesn't support audio in on the PC, unless I use USB mode.. Ohh dear here we go again!! mixer anyone! (if I connect in USB mode I loose the buttkicker.) so I leave it on speaker mode with the headset plugged in this Mutes the speakers and provides the audio via the headset. On the PC you can configure a separate comms device (standalone mic) There's got to be a better way.
Might be a project in here to build a digital switch with dual outputs!
