Can’t get surround sound

Wim · 06-12-2014, 09:35 AM

We have just tested this on an Onkyo HT-R538 which is what we have for system test and 5.1 audio works. Is 5.1 definitely selected under the speaker configuration?

(Note: we show Stereo and 5.1 only)

Thanks for verify that it is possibly to get 5.1 throughout HDMI. May I ask what OS and with docking station you used?

I only have stereo or 5.1 Surround and I have tested both. The sound comes out different so I’m sure.

I will try to find another receiver to test on. But because it works then I use the computers displayport I think the receiver is fine.

It was checked with a Targus ACP70 dock on Windows 8.1 (to check the original problem posted in this thread).

I have now tested on a newer receiver.

Then I use the display port the receiver say it get a Dolby D signal.
Then I use the dock and Displaylink the receiver says “Multi in”.( So the 5.1 sound works on the newer receiver)

I thought Displaylink just pass-through the sound, but it seems it process and changes it in some way. The source is Dolby D.

I have tried to google it and I think it makes it to PCM multichannel. I don’t think my old receiver can handle PCM multichannel so that should explain my problem. And if I understand it right, if I set the source(computer/Displaylink) to Bitstream it will pass the signal unprocessed to the receiver.

Have I understood it right and is it possible to set Displaylink to Bitstream so it just pass-through the signal?

I've checked with the engineers and yes, your understanding is correct. It is PCM only, not compressed bitstream.
