I'm an AV geek who's installed thousands of Home Theater systems - here's my thoughts:

  • Your HDMI is too long. Anything after 50' is unreliable and exceeds the quality ratings of the standard. You'll need to get an amplifier (HDMI Balun) or switch to a shorter cable. I've had problems like this in the past when installing systems for churches or airports that require long cable runs.

  • I don't know if your computer supports 7.1 out of the box. Most of the time 5.1 is going to be your standard . Check with HP to see if it does support 7.1; if it doesn't, an external sound card is going to be your best bet.

  • Your receiver doesn't support HDMI, so I understand why you're running it through the TV first. I'd check that your TV can handle 7.1 through its audio output. It may also be a setting you'd need to configure.

How are you sending the audio from the TV to your receiver? Which output on the TV, using what cable, going to which input on the Yamaha?

Model numbers for your computer and TV would be really helpful in trying to figure this out.

Let me know! Happy to help you troubleshoot!

Thanks for providing that!

After looking through the product manual for your Samsung TV, I see that it is only able to output in 5.1 while using DTV (air) signal. For HDMI as an input, it will only output in 2-channel stereo through Optical Out.

Here's the documentation I found:

-----------------------------------

Listening through a Receiver (Home Theater)

You can listen to sound through a receiver instead of the TV speaker.

1. Press the TOOLS button. Press the ENTERE button to select Anynet + (HDMI-CEC).

2. Press the ▲ or ▼ button to select Receiver. Press the ◄ or ► button to select On or Off.

. Press the EXIT button to exit.

If your receiver supports audio only, it may not appear in the device list.

The receiver will work when you have properly connected the optical in jack of the receiver to the DIGITAL AUDIO OUT (OPTICAL) jack of the TV.

When the receiver (home theater) is set to On, you can hear sound output from the TV's Optical jack. When the TV is displaying a DTV (air) signal, the TV will send

out 5.1 channel sound to the Home Theater receiver. When the source is a digital component such as a DVD and is connected to the TV via HDMI, only 2 channel sound will be heard from the Home Theater receiver.

If there is a power interruption to the TV when the Receiver is set to On (by disconnecting the power cord or a power failure), the Speaker Select may be set to External Speaker when you turn the TV on again.

-----------------------------------

Based on this, it seems the issue is with your TV and not the laptop. The only way around this is going to be to either upgrade the receiver to one that supports HDMI in, then run HDMI out from the receiver to your TV, or upgrade TVs.

Sorry to give you the bad news - I was hoping there was a software problem with the laptop that would have been a lot easier to fix (and a whole lot cheaper!)
