I've run into a stumbling block that is totally stumping me.

I've got a Sony Bravia KDL-55EX620 LED LCD tv, connected to it is my Yamaha HTR-4064 receiver, connected to that is my source, an HTPC, which is a Gigabyte H61N-USB3 using an Intel i3 2120. I'm using the onboard graphics, and have it all connected ONLY via HDMI, no optical or anything like that.

The receiver is capable of decoding HD audio formats via HDMI, the computer is capable of bitstreaming them( I think ?), but the TV is the thing that shows up in the Sound Properties page in Windows 7. On the Sound Properties page, it tells me that the TV's "Supported Formats" are only Dolby Digital, Dolby Digital Plus, and DTS.

My problem is, of course, that I can't get ANY HD audio formats, like True HD or DTS-MA to play !

I've tried every setting I can think of in the receiver and tv to try and make the computer see the receiver as the "destination" of the audio signals, but the "Sound" page in Windows 7 always only shows the "Sony TV" as the HDMI connection.

What am I doing wrong ?

What did I miss ??

Thanks in advance...

What media player are you using on HTPC ? Might not have right audio codec.

....or player. I couldnt get BSPlayer to bitstream, but MPC works great.

Is your Yamaha AVR set to 'Pass-Through' ON?
Pass-through allows the AVR to send the signal from the HTPC to the display device even if it is turned off/stand-by.
This extends the audio chain to the TV and the HTPC sees the two TV speakers.
Turn off the feature to terminated the audio chain at the AVR and see if the AVR shows up in playback devices.

Ok, I'll give that a try, I *think* I've tried everything, but we'll see about that kind of setting. So I'm looking in the receiver menu...

None of the players allows me to do what I want to do, I've tried MPC HC with Lav Audio, and Media Center using FFDShow, also tried KMPlayer and Zoom Player free, but they are a daunting setup task I'm not up to in the short amount of time I've been trying to solve this issue....

It sounds like this is the issue since its acting like the AVR is not even there.

Ok, tried it, the end result was the HDMI in the Sound properties now doesn't have a name, its blank, and it doesn't have any capabilities where before, at least I could bitstream DD DD+ and DTS...

I don't think this is going to be something that there is a solution to, looks like another HDMI failure. Just LOVE HDMI, btw...such a convenience to be totally at the mercy of uncaring consumer electronics manufacturers who, if they don't get it right the first time, NEVER correct it...

Looks like the Yamaha has some quirk that doesn't allow its capabilities to be seen by my HTPC, regardless of the setting I choose.

This is partly Intel's fault too, I think, since I *had* this working using an AMD HD5450 card in a "lesser" HTPC...

Yup, epic fail. Tried again, shut computer off, pulled power, pulled HDMI, shut off receiver. Powered computer, plugged HDMI, powered receiver. Even though "pass through" was set to OFF in receiver, Sony TV was still the only device that showed up via HDMI....thanks Intel and Yamaha....

and I've got the bug in the Intel properties page where setting the output to "Full" won't stick...really great products...really great...

Do you have the EMI driver installed? I would try uninstalling the graphics driver. And reinstalling maybe it will "detect" the AVR. Sounds like some sort of EDID issue. I would think it should be fixable.

Is your Sony TV capable of audio return (mostly used for 3D setups)?
Your AVR has an "audio return" HDMI output. Try turning that off too.
