Hi All,
I am trying to connect my PC's HDMI out to the Yamaha RX-V375 receiver and I want to split the output so that the video part of it goes to a Epson 710HD projector and the audio plays via speakers connected to the receiver.

Even if I set the Amp option to On in the Audio Output section of the HDMI menu item, the audio never plays on the speakers connected to the receiver. However, everything works as expected if I use Xbox 360 as the source instead of my PC.

Any ideas/suggestions? Any help is very much appreciated, I have been struggling with this for the past couple of days and i am sure i am missing something basic.

Regards,
Arun

The AVR should show the type of audio arriving from the PC. What does it say?

The Signal Info option has the following info:

Format: PCM
Channel: 3/2/0.1
Bitrate: ____
Input: HDMI 1080p
Output: HDMI 1080p

I tried running the test option from the PC's Playback devices list and the test sound comes out of the AVR speakers just fine.

Thanks for the help.

That says the PC is sending 5.1 PCM. What does the display say when you play the test tones on the PC?

It says the same thing (PCM 5.1) when the test sound plays. However, with Xbox it says Dolby D 5.1 and that works well.

what kind of files are you trying to play back on your PC. Odds are that the files "conversion" is either not compatible with the audio option or the conversion is "unsuccessful". Since the test tones on the PC are being generated correctly (and output), I suspect this is your problem.

I tried it with Netflix and Youtube and both do not work. Would upgrading to a video card that supports Dolby Digital work?

I would look closer at the options that you have setup on your computer for the card. Further, does your computer have a drive (ie. dvd /cd) in it. IF so, does that work correctly?

Thanks for the hint. Re-installing my video card driver fixed the issue. Weird, but it works now smile.gif
