Reddit reviews 3.5MM Stereo Male to Two RCA Female 6 inch

It won't. It's 3.5mm in size, but it's still an optical signal. You'll need a Digital to audio converter. Something like this. Then a cable like this one and you are good to go.

Or if you want to make your life easier. Get this cable and use the ps3 av cables.

Sound needs to go into the pc audio input. This should do it.

You'll need something like this

And put it in the 3.5mm port next to the Green input

On second thought, don't buy the Xbox Brand one for $40. Get a third party cable. It works just as well. You might need to get an adapter for audio depending on if it comes with it or not.

This is a good idea. Use This.
You have the xbox audio into the adapter plugged into your computer's MIC port and then install Audacity to record the audio. You can then save it, but need THIS extension to save mp3s

Note: both of these methods go without use of a switchbox.

one of these and one of these That should do it.

Yep. Some models of AT TT'S come with an RCA to 3.5 adapter to hook up to a computer but if yours didn't you will need this.

I should also mention that

• DVI and HDMI are the same video signal, DVI can carry audio, but it's rarely used. This is why DVI to HDMI adapters are so easy, and cause no loss in quality.
  
• Additionally, DVI can contain a VGA signal in it, most computers will typically do this. Thus most DVI to VGA adapters are doing this, since actually converting a digital DVI/HDMI signal to analog VGA requires an expensive adapter. This means that HDMI to DVI to VGA will not work.
  
• Component is an analog signal that is similiar to VGA, but is missing a part, which is easily figured out by output device. Thus, Component to VGA, is fairly easy and cheap.
  
• Don't forget that you need to get audio from all these devices as well. This and This Would allow you to use a generic pair of headphones for almost any device.

Yes, they will definitely sound better than your Logitech speakers! I have one that I use in mono in my bedroom and it's very pleasant with a lot of headroom and good bass. Just remember not to put them too close to the wall behind them. Please post as to whether you like them! Also, you can probably return them.

You also should just use RCA to TRS cables since it's not balanced anyway. You should also think about adding an RCA (female) to 3.5mm cable (like this: http://www.amazon.com/Hometheatre-Female-Splitter-Cable-6-Inch/dp/B0016LC5VY) so you (or a friend...this sounds like a college setup?) can easily hook up a phone or mp3 player without having to mess with the back of the speakers.

the official microsoft vga cables (the original grey ones, not sure of the new black ones) will have all the adapters and gender changers you need in the box.

the only thing you need is a digital audio cable to connect the Astro A40 (this is the same cable you will need with the xbox one)

http://www.amazon.com/AmazonBasics-Digital-Optical-Audio-Toslink/dp/B001TH7GSW/

(if you want to use surround with the A40s. if you do not want surround you dont even need this cable)

if you will only be using the A40s than you are done. if you want to use the monitors built in speakers, you need this kind of adapter. again, it comes in the box of the original grey cables, i am not sure about the new black ones:

http://www.amazon.com/C2G-Cables-40645-Stereo-Adapter/dp/B000J1H4VI/

if this is too bulky to fit at the back of your monitor, the same thing exists in cable form:

http://www.amazon.com/Hometheatre-Female-Splitter-Cable-6-Inch/dp/B0016LC5VY/

This is possible, but you'll only get one channel of sound for both inputs, so you'll hear game sound in one ear and chat in the other. You'll need one of these and two of these. After you get those, connect the male 3.5mm ends to the sources, and then the red or white wires to the female 3.5mm adapter. Once that's done, you can plug in your headphones into the female 3.5mm jack and enjoy.

Left and right audio cables connect to something like this and that goes to my monitors audio input or any other audio device

Optical cable and HDMI will sound the same. Sounds like you already have it hooked it?

I use one of these to hook my computer up to my receiver + a double RCA male cord:

This one looks okay. For audio, you need RCA to 3.5mm, like this or this.
