Mine is the same as well. I use optical out and have the Blu-ray settings to output Bitstream via optical, seems to work ok, I get sound out of all the speakers.

They started this for people with more than one HDMI source, so they could run it into the receiver and have only one HDMI cable running to their TV's.

To get PCM you have to make sure the receiver handles HDMI video AND audio. If you see the words "pass-through" walk away!

In order to utilize uncompressed audio via HDMI, the receiver must have version 1.3. Older versions of HDMI are useful for video signals or multi-channel SACD or DVD-Audio formats. Versions 1.1 or 1.2 will not output the new lossless audio formats Dolby TrueHD or DTS HD. There's not enough bandwith.

I do have the HTR-5960 as the receiver for my home theater system. I'll try sending you a PM either tonight or tomorrow with the settings I use for games, movies, and music.

Sorry but that is not true, all versions of HDMI will support up to 8 channels
of 24 bit pcm at sampling rates of up to 192.The key factor is what the reciever does with the signal, not all accept the audio signal but only act as a video pass through.

Based on the "Detailed Specifications" tab near the bottom of this page:

...what do you think the best PS3 setting is for this? Linear PCM or Bitstream? Also, why is this setting ("BD/DVD Audio Output Format (HDMI)") under the "Video Settings" menu on the PS3? Wouldn't it make more sense under "Sound Settings"? Or am I unclear on something?

Thanks again!

weird, it says it can do PCM playback, and yet has no HDMI inputs. i've read over and over again that the optical/coax inputs don't have the bandwidth to support PCM. not sure how this does PCM.

either way, you'd always need to keep the PS3 on PCM, not Bitstream, as the PS3 can't bitstream DTS-HD and Dolby-HD, but can only send it as PCM to the receiver. however, still not sure how this device handles the PCM properly without HDMI hook up.

Probably would confuse some people...it would make sense to have it under the audio settings.

Any, looks like the soundbar is 2 channel. I assume you have this hooked up to your receiver via Optical. In that case, I would set my PS3 to Linear PCM as you can benefit from 2 channel loseless audio.

Optical connection does support PCM...but only in discrete 2 channel. It doesn't have enough bandwidth for the full 5.1 loseless audio.

I own it, and there's definitely two HDMI inputs and one output. So, does that make more sense to your answer, then?...

Thanks for the input!!!

No receiver. I think this kind of acts as a receiver, which is why I was unclear what settings to use. I have my PS3 and Comcast DVR going into the soundbar with HDMI cables. Then I have one HDMI cable going out to my TV. There's also a subwoofer attached via standard digital coax out of the soundbar as well...

Thoughts?...

ah that's right, it is self-powered. Linear PCM is the way to go. You will be getting loseless audio with that soundbar.

PCM stands for "Pulse Code Modulation," and any digital A/V receiver uses it today. PCM can be compressed or uncompressed. Uncompressed PCM is also known as Linear PCM, or lossless audio. Compressed PCM is also known as lossy audio, and that can be found with traditional Dolby Digital or DTS.

Just because the receiver says it can transmit PCM, it doesn't mean it's uncompressed PCM. If the receiver only offers a digital optical input, then it can process 2 channel uncompressed PCM, or 5.1 channel compressed PCM.

So, that being said, does that soundbar I mentioned above not transmit uncompressed PCM? How can I tell?...

If your PS3 is set to Linear PCM, it decodes the audio internally and sends uncompressed audio via PCM to your soundbar...aka loseless audio.

If you set your PS3 to Bitstream, it does not decode the audio and bitstreams it to your receiver, or soundbar in your case, for processing. I doubt your soundbar has the HD codecs. That is one of the main problems with the PS3 as it cannot bitstream loseless audio.

kingofgrills · 03-26-2009, 12:19 AM

That sound bar does not have built-in lossless audio decoders. If you look at the detailed specifications of the link you provided, here is what it says about PCM playback:

PCM audio (fs = 32 kHz, 44.1 kHz, 48 kHz), DOLBY DIGITAL, dts, AAC, Binaural, Analog Stereo

Off the top of my head, I can't remember what sampling rate most lossless tracks are encoded at, but 48kHz stands out in my mind. If your player can decode the track, and it's not output greater than 48 kHz, you won't have a loss of audio quality.

I may be unclear. Why is that a problem if (as you also said in that post) the PS3 can decode the audio internally and send uncompressed audio via PCM?...

Like, isn't that pretty much the same end-result? If the PS3 could bitstream lossless audio, why would that be better?...

Thanks for the informative posts, everyone!...

If you have a receiver that can decode loseless audio, can you play a blu ray in the PS3 and get the loseless audio then?

exactly, you'll need a receiver that has all the lastest HD codecs.
