Hi, Brandon. I believe that your new YHT-390BL system used the HTR-6130 receiver. That receiver does HDMI switching (so that you can use the receiver to select different sources), but it does not process audio over HDMI. Therefore, you can run the video through the receiver just fine. For audio, though, you'd need to use another connection - preferably a digital audio connection.
From the owner's manual on page 14:
Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video
monitor.
To enjoy the sound from speakers connected to this unit,
–make an analog or digital connection besides the HDMI connection (see page 16).
–mute the volume of the connected video monitor.
If you need any help with setting that up, just let us know. We'd be happy to help.
