English is not my native language as well
The problem must come from there I think

It's simple. I try more simply.
Normalize levels on downmix is activve + enable passthrough is not active = stereo
Yet I'm 5.1

[jjd-uk]

I'll see if I can help out here.

Is what you're trying to say is with Passthrough off and Channel Configuration set to 5.1 you get something like:

DTS 5.1 In -> PCM 2.0 out

What you want is:

DTS 5.1 in -> PCM 5.1 out

For this to work your HDMI must report as being PCM 5.1 capable, so maybe in your case it's reporting as only PCM 2.0 capable even though you're connected to an AVR which should support this.

Provide a debug log_file (wiki) of you playing something where you want 5.1 out and post actual screenshots of your audio settings to somewhere like imgur.

yes!
that's exactly it.

For information. The display of the amplifier gives me this: multichannel PCM

Provide a debug log_file (wiki) of you playing something where you want 5.1 out and post actual screenshots of your audio settings to somewhere like imgur.

OK. I got this.


thank you very much

OK now we're getting somewhere, if the AVR shows multichannel PCM then that would suggest it is indeed receiving 5.1 channels, so your issue is either:

1. A sound mode is engaged on AVR forcing stereo output when PCM 5.1 is received.
2. A 5.1 channel layout is being received by AVR however the audio XBMC is sending only contains audio in the left & right channels contain with the other channels containing silence.

Most AVR's will have either an OSD info display or a speaker layout display on the lcd front display showing the received channel layout, use that to confirm 5.1 layout is indeed being received. It might help if you could get a close up photo of the front display so we can clearly see what the AVR shows which together with a debug log should show what's going on.

Thank you for your help jjd-uk

My AVR (Harman-Kardon AVR1710) is minimalist at the display. I do not have the detail of the audio config on the screen of the device or on the OSD.
By cons I know it's perfectly configured 5.1
As with hdmi passthrough on it is OK. But perhaps there is there a problem in multi-pcm!?

There is no sound mode engaged on the harman. Otherwise it would display "surround ..." instead of multi-pcm
I think it is sending the 5.1 but with silence on the effects speakers.


Here is the log:

EDIT :
I see in the log :
Physical Format: [lpcm] Mixable Interleaved 2 Channel 16-bit Signed Integer LE (48000Hz)

strange ...

I see you're using the Default device which only reports 2 channels. hence the stereo, however it looks like the sink is trying to create a 8 channel PCM layout (which fits multichannel PCM being seen on AVR), so maybe OS-X is doing something on top as you've got the Default device selected.

Have you tried setting Audio Output Device to HDMI? Have you tried setting Output Configuration to Best Match?

As it's starting to stray is OS-X into knowledge being needed which I'm totally clueless about, so I think I'll have to bow out now, hopefully there's enough here now for Memphiz to understand the issue.

[jjd-uk]

Just had a look at the AVR manual here http://www.harmankardon.co.uk/tl_files/c..._OM_EN.pdf

Try with following set in AVR if not already:

HDMI Audio to TV: Off
HDMI Link: Off

Maybe a bug in OSX ?

Yes I tested all combinations possible (very long!).
I still only stereo.

Oh thank you very much. You are going to read the documentation!

They are both OFF.
I never use the sound of the TV.

mhhh it doesn't look to bad imo:

Please goto audio-midi-setup in osx and ensure in the speaker layout that those channels are mapped right and you are hearing the test sound as expected.

Also please set it from optimized to best-match in xbmc audio settings.

Hello Memphiz,

I found !!!!
I redid all the tests from the beginning
It's really complicated!

does it work putting this:
- Resample quality = medium
"High" does not give any sound.
He seems to have a problem with this option!

but!
there is still further manipulation.

While I was watching a movie you have to:

- In audio-settings: I activate "enable passthrough" then I canceled (ON and OFF in fact)

and then everything is OK
really strange !!

[Memphiz]

nah that is only a bad workaround and not a real solution. Did you do what i suggested?

[superyo]

Yes, absolutely I tested. I just tested again.
It does not work.

Damaged preference file perhaps? But which one?

This works fine with you?

[Memphiz]

You are the first one i have seen here reporting a problem like this. (yeah it works fine for me of course).

[superyo]

this confirms what I think then.
there is a problem on my mac and / or XBMC!

just have to find which one !
