Question 1

Does it work with other *standard* HMDI sources?

Accepted Answer

If you meant HDMI, then it does work.  According to the instruction manual that came with Turtle Beach XL1 headset, connect red and white of a composite cable to this audio adapter, and connect a HDMI cable from Xbox 360 system to your TV.

Question 2

Does it work with other *standard* HMDI sources?

Accepted Answer

This plugs directly into the back of the Xbox's analog video/audio output, not the HDMI output. So if your question is asking if this will work on anything else, it's negative.
