So, I recently ordered two floor-standing speakers, and a center channel speaker. Meaning I'll be upgrading from 2.1 audio to a 5.1 set up. I've got a few questions, and am looking for some advice on how exactly I should connect both my PC and 360 to my receiver for 5.1. So, here's the background.
My receiver is a Denon AVR-1312. Here are is the back of it.

My PC has an optical-audio out connector, which I plan on using to send 5.1 to the receiver. I was wondering if it's possible that there is a "splitter" to have a device take two optical audio lines in, and output them both on one.
I guess my first question, out of uncertainty, is does optical audio even support 5.1 audio in the first place?
If not, I then come to this:
My receiver supports HDMI 1.4a standards. I don't like HDMI all that much, but would it be possible to send HDMI from my PC to the receiver and play in 1440p while using 5.1 audio? Also, will there be enough "bandwidth" to let me play at 60Hz?
I normally use my Xbox 360 with HDMI through the receiver, but as of last night I feel like I'm noticing some input lag. Maybe it's because something was a little too hot, or not running as it should... (or maybe I was just having bad connection games)
But any advice would be appreciated.
