Sorry if this has already been answered but I keep finding conflicting opinions online.

Facts: I just got my Astro a40 2013 edition in the mail and I am trying to find the best way to hook it up to my Asus P9X79 Deluxe motherboard.

Question One: At the moment i have it connected to my computer via 3.5mm aux. Can 3,5mm aux carry 7.1 sound to give me the most of my astro headphones?

Question Two: Does an optical fiber cable (I believe this is the one that uses light) carry 7.1 sound?

Question Three: If neither of the two cables above carry 7.1 what cable would i need to connect my Astro a40 to the P9X79 DTS connect 7.1 sound output.

Thanks in advance,
Steve

q1: no. 3.5mm computer audio jacks carry only stereo audio.


q2: yes. optical spdif is capable of carrying 7.1 sound.

q3: in general for surround sound there are 3 options. connecting with 3.5mm jacks (for 7.1+ microphone you need 5 plugs), connecting with optical spdif (the one which uses light) or connecting with coaxial spdif (it looks like an orange colored rca jack typically).

also... if an external device such as some headsets have an internal soundcard (inside the product itself) they can connect up to usb instead of from the speaker jacks since they are bypassing your onboard soundcard in this case. i'm not sure if the a40 does this or not as i couldnt find any easy to find reference showing what cable ends it comes with.

from a brief glance it looks like you must connect your headset to the little control box and then connect that to your pc by either spdif or usb... not quite sure perhaps you can elaborate what cables it comes with.

I think this is what you are looking for. Sorry if it isn't.

These are the cables that come in the box.

yes. as far as i can tell without delving too deep into the manual... that box (mixamp) gets connected to the computer. the headset then connects up to the mixamp via the a40 console cable.

if that spdif optical cable works with your motherboard... i'd use that.

isnt there a connection diagram shown in the manual?

Now that i know spdif supports 7.1 I'll use that over DTS connect. Thanks for the quick answer.
