Thanks for the question.

Depending on how your AV receiver is setup it may be just easier to take the HDMI from your PC directly to your TV. To answer your question, yes the AV receiver would treat the PC input as just another HDMI source, and output it to the TV.

One thing you should be aware of is that *some* PC's do NOT output audio over HDMI. The easiest way to check this would be to goto the sound properties in the Control Panel on the PC, and see if it has anything "HDMI Output" related. Also check to see if it allows you to set that as default.

I hope that clears things up for you and helps out. If you have any further questions feel free to ask them.
