HD 4000: Passthrough for HD audio formats

HD 4000: Passthrough for HD audio formats

[Frederik Vogelsang]

Hi,

I am using a Core i5-3475S on a ASUS P8H77-I. The system is connected
to my amp through HDMI. For some reason I cannot get passthrough of
DTS-HD MA or Dolby TrueHD to work properly. On my HTPC with an ION2
chipset I can use

aplay -D hdmi:CARD=NVidia,DEV=2,AES0=6 -c8 -fs16_le -r192000 dtshd_test.spdif

and the receiver recognizes and plays the DTS-HD MA stream. On my
Intel system I am trying the exact same thing (different card name,
obviously) and the receiver only plays noise (shows 7.1 PCM instead of
DTS-HD).

Am I doing anything wrong? Are there any configuration options I am
missing or kernel module parameters? I am using the latest stable
xf86-video-intel driver and Linux kernel.


Regards,
 Frederik

I guess the developers might look at your problem on Monday, but please
note the specific versions. ALSA version might also be interesting. Do
you use PulseAudio? Have you tried some live systems? And lastly is this
a regression?

Anyway, please also provide some log files as documented in [1].


Thanks and good luck,

Paul

Re: HD 4000: Passthrough for HD audio formats

[Frederik Vogelsang]

Hi Paul,

thanks a lot for your reply. I am not using Pulseaudio, just plain
ALSA. These are the software versions I am currently using:

Linux: 3.5.0 (always on latest stable)
Alsa: in-kernel driver, alsa-lib 1.0.25 (always on latest stable)
xf86-video-intel: 2.20.0 (always on latest stable)

I do not think these matter, but I'll include them nonetheless:
xorg-server: 1.12.2
libdrm: 2.4.33
mesa: 8.0.3

I am not using a Live-System. This is a Gentoo Linux system, booted from UEFI.

This is what is already working:
* 3D acceleration
* Sound (except from this very issue)
* DTS/Dolby Digital passthrough
* 7.1 LPCM

This is what does not work:
* DTS HD/Dolby TrueHD pass-through/bitstreaming through HDMI 1.3

The driver even recognizes the audio formats supported by my AV receiver:

I am not sure if this is a regression. I do not have any other Intel
systems I could use for testing (like Sandy Bridge or earlier), only
my Ivy Bridge build with a HD4000. I can only say that DTS HD
passthrough works in a similar Linux system with a NVidia GT 430 using
the command above, so it can neither be the cable's nor the receiver's
fault.

Hi all !

I already reported this problem here:
https://bugs.freedesktop.org/show_bug.cgi?id=49055

I was also in emailing on this problem with Intel developer Wu Fengguang.
It is probably an Intel driver problem.
His last email (back in may) was:

"Hi Attila,

Sorry for the delay! During the time I consulted another Intel
developer but still remain clueless on this problem. I'll try to
reach the Windows driver developers for help..

Thanks,
Fengguang"

I'll try to ping him if there is any newson this.

Cheers,

Attila

Re: HD 4000: Passthrough for HD audio formats

[Frederik Vogelsang]

Hi,

thanks for your feedback, Attila.

2012/7/24 alanwww1 <alanwww1@gmail.com>:
> I already reported this problem here:

I see. I did not search bugzilla yet, because I thought this feature
was related to my pretty new hardware components. It's a little
disappointing to hear that HBR sound passthrough does not even work on
Sandy Bridge yet.

> I'll try to ping him if there is any newson this.
That would be nice. Any developer information on this (like "we are
working on it") would be appreciated.

 Frederik

See the comment I've added. Retesting on 3.5 (and if that doesn't work on
3.6-rc1 respectively drm-next) is required, otherwise we'll have known
hdmi infoframe issues. Which could very well explain why hbr doesn't work.

Re: HD 4000: Passthrough for HD audio formats

[Frederik Vogelsang]

Thank you for your statement, Daniel.

Is there any way to work around the HDMI infoframe issues you have
mentioned? Are there any patches I could try?


Regards,
 Frederik

Other people have already tested 3.6-next and it did not help. So I guess
the issue is with the sound driver, at least I'm not aware of anything
that we should set up on the drm/i915 side, nor of any bugs with our hdmi
support.

Sorry that I can't help further :(
