When using Elgato Game Capture HD, you can record Game Audio and Chat Audio from the Xbox One if you purchase a few inexpensive cables.

This cable makes it very easy to record Game Audio and Chat Audio from the Xbox One.
See this video and article for more information:

Our advice is to use the Chat Link cable, but if you don't want to, see the instructions below.
To record your own voice, connect a separate microphone to your computer:
How do I use Live Commentary?
What You Need
1. The Microsoft Stereo Headset adapter

2. A CTIA Y-Cable
You will need one like this:
But be careful - there are 2 different types of these Y-Cables named CTIA and OMTP.
What you need is the CTIA one. For more info see the "Standards for audio jacks" section on this page:

3. Another Stereo Y-Cable
This cable will look similar to the CTIA Y-Cable.
The difference between both cables is the 3.5mm plug from the stereo Y-Cable has 3 segments, the CTIA has 4:
Another kind of splitter cable will also do the job:
4. A Stereo Y-Cable RCA to 3.5mm cable
5. The component adapter that shipped with the Elgato Game Capture HD
6. A Headset
For example, the Turtle Beach X11 with separate green and pink 3.5mm plugs.
If your headset does not have a separate 3.5mm plug for the headphones and microphone, but instead only one combined 4 conductor 3.5mm plug for both, then you will need another adapter to split the microphone and headphone signals apart.
These are sometimes known as a "Headset Splitter".
Connect your 4 conductor 3.5mm plug from the headset to the adapter to the Headset Splitter to get separate microphone and headphone 3.5mm plugs.
7. A 2nd Mic to capture your voice for the recording with the Elgato Game Capture HD.
For example, a Blue Yeti USB mic.
