Hey y'all! I purchased a Sony STR-DG720 so that I can finally get LPCM from my PS3 via HDMI. This receiver does not feature analogue inputs, which is how my HD-DVD player has been hooked up. My question is will the Tosh send 5.1/7.1 LPCM via HDMI? Thanx in advance!

Yep. The A1 decodes internally and sends the info via PCM track to your receiver.

Thank you Pat! That's perfect.

Re: Question about Toshiba HD-A1 and HDMI

I'm an HDMI newb, so please be patient with me. My receiver is a Sony STR-DG720. I've got a PS3 plugged into the "Blu-Ray" HDMI input. The HD-A1 is plugged into the "DVD" HDMI input. The PS3 works without a hitch. I LOVE lossless audio! But for the life of me, I can't get the receiver to recognize the HD-DVD player. It's not the cable - I initially used it with the PS3. The HD-A1's set up menu isn't as detailed as the PS3. I'm at a loss. Any tips for an HDMI newb?

Re: Question about Toshiba HD-A1 and HDMI

I've got an STR-DG910, which is similar to your receiver (last year's model, but same basic family). I'm running an HD-A3 through my "DVD" HDMI input. So it should definitely be do-able. A few questions...

1) When you say the receiver won't recognize the HD-A1, do you mean for the higher-end audio CODECS (DD+/Tru-HD/etc), or for multi-channel decoding? Or do you mean not at all, period -- no image/no sound/no nothing?

2) Do you have anything plugged into the component video "DVD" ins? That SHOULDN'T matter, since HDMI is supposed to take precedence over other devices on the same input bank. But just checking.

Thanx for the reply.

1) I mean it's not recognizing it at all. No sound. It recognizes that the HDMI input is being used, but no speakers light up on the display as is the case with the PS3.

2) No other inputs are being used.

Re: Question about Toshiba HD-A1 and HDMI

sounds like there is a setting that is not set right. Check the set up in the A1 and see if it has an "override" for the audio. If you were using analog before, it might still be trying to use analog. I had trouble with my cable box cutting out the sound when I used HDMI, so I used an override to set up the sound via optical and it works perfectly now. It might be something similar to this.
Good luck.

Re: Question about Toshiba HD-A1 and HDMI

I think I know what my issue is - The HD-A1 will not do component and HDMI at the same time. In order to use HDMI for audio, I need to use it for video. Fair enough. There might be a snag in that my projector, the Infocus SP4805 will only do HDMI via DVI adaptor. But if I recall, the DG720 doesn't like HDMI/DVI adaptors? Am I right? More importantly, am I out of luck?

Re: Question about Toshiba HD-A1 and HDMI

Ah, your setup is a bit different from mine -- My projector has an HDMI in, so I can run HD-A3 [HDMI out] -> [HDMI in] Receiver [HDMI out] -> [HDMI in]Projector . All neat and tidy.

The DG series of receivers is nice in that it will transcode component in to HDMI out, which I've taken advantage of... but unfortunately it won't do the inverse.

It's been a while since I dug into the detailed discussions on these receivers, so I can't remember if people were having trouble running a DVI -> HDMI adapters from a source to the receiver's HDMI in, or with running an HDMI -> DVI adapter from the receiver's HDMI out to a display... or both. Hmmmm.

Re: Question about Toshiba HD-A1 and HDMI

So, to make things clear, where are things being plugged in? A1 to receiver and receiver to projector, right? For the A1, you have HDMI, and to the projector you have HDMI with HDMI/DVI converter?

There should be a setting in the A1 (I have the A2) that outputs audio through HDMI. Once you choose HDMI Audio Out, you shouldn't have a problem. The HDMI to DVI adapter shouldn't make any difference whatsoever, because your projo only handles video, not audio. The receiver doesn't send the audio through HDMI to your projo.

Also, what audio settings do you have on your PS3? PCM?

"but unfortunately it won't do the inverse."

That's because of copy projection. HDMI (and DVI) have the HDCP protection scheme, which is not supported through component. I haven't yet seen a receiver that will do HDMI to component transcoding.

Resurrecting this, because I've been away for a while.

To answer some of Pat's questions:

Right.

Correct.

The HDMI setting in the Setup Menu is not that specific. It allows you to choose what sort of audio signal will be processed via HDMI (Bitstream, PCM, Downmixed PCM, and Auto). There is a similar setup option for SPDIF, but there is no setting that tells the HD-A1 to exclusively send audio out by HDMI, as opposed to optical or SPDIF.

This is true. However, since the player will not split HDMI signals (audio independant of video), my assumption was that I would need to use the HDMI exclusively for both audio and video. This meant using the HDMI-DVI adapter for my proj. But according to the Operating Instructions, Sony does not "recommend using an HDMI-DVI conversion cable. When you connect and HDMI-DVI conversion cable to a DVI-D component, the sound and/or the image may not be output." There is a thread over at the AVS forum that confirms the incompatibility issue. And my own experience confirms it as well.

PCM, yes.

So can anyone confirm that 2nd and 3rd gen HD-DVD players allow splitting up of video and audio by way of HDMI?
