Probably not.  I don't have any details about the hardware in that
particular receiver, but there's no guarantee that the voltages being
used are appropriate for a sound card input.

You can read more about IR audio hardware here:

http://www.lirc.org/ir-audio.html

If your receiver is compatible with the hardware described there, it
will work, and if not, it won't.  Worst case scenario is that plugging
it in will fry your motherboard (but that's highly unlikely).

Remember, it's not really a stereo jack.  It's just a plug that has
the same shape as a stereo plug.

In all likelihood, your receiver is expecting the three connectors on
the plug to be power, ground, and signal, while your soundcard is
expecting ground, left, and right.  Since the sound card does not
provide power on the line-in jack, and the receiver requires power, it
isn't likely to work.
