The pass through is set up with KURO LINK, which is just what Pioneer calls HDMI-CEC. Check your manual chapter 8 for how to set it up.

If I were you, I would skip the 5.1 surround speakers you bought and just build a good quality 5.1 system around the TSi fronts. When watching movies, a good center channel speaker is critical. Short of that, you can set your receiver up for a "pantom center" where the front speakers play the center content. If you pick up a CS10 center to match your fronts, you will find dialog will be much better in movies. Add a good 10 or 12 inch sub and some inexpensive surround speakers and you will be set for about the same money.

BTW, there is a dedicated 1021K owners thread on AVS forum.
