PulseAudio: Implement DTS-HD and TrueHD #16693

fritsch · 2019-10-01T16:48:15Z

With Pulseaudio 13, support for DTS-HD and TrueHD IEC was added. Sadly there was barely any documentation on how to use it.

Make sure to add the formats to your sink (check its number with pactl list sinks, in my case it's 0):

pactl set-sink-formats 0 "pcm; ac3-iec61937; dts-iec61937; eac3-iec61937; truehd-iec61937; dtshd-iec61937"

If you want to test, please start pulseaudio with -vvv as arguments and provide a link to your kodi debuglog. Thanks much.

@tanuk @ford-prefect Any idea how these new formats should be probed and work?

xbmc/cores/AudioEngine/Sinks/AESinkPULSE.cpp

ford-prefect · 2019-10-02T02:44:09Z

Hey @fritsch! Unfortunately, I missed landing a bunch of requried changes before announcing DTS-HD/Dolby TrueHD support. The required work is here -- https://gitlab.freedesktop.org/pulseaudio/pulseaudio/merge_requests/24

I also missed adding that to pavucontrol for an easier way to enable it, so quite poor showing all around, sorry about that.

fritsch · 2019-10-02T07:23:27Z

Thanks much @ford-prefect - we are in no hurry here as next major Ubuntu will ship 13.0 only. Do you plan to add those fixed to 13.1?

I would then change the patchset to only enable it for 13,1,0

Codewise it's okay? So nothing fancy, just: 192 khz + 16bit + 8 channels + HD-Format?

One thing to add: Modern AVRs don't consume DTS-HD HR anymore with 8 channels 192 khz, for those we changed our IEC encoder to also send 2 channels / 192 khz, while DTS-HD MA will still be sent as 8/192 khz.

Is that something PA might also need to do?

fritsch · 2019-10-02T07:50:23Z

Patch for PA and DTS-HD HR (Updated!):

From a3d97abd14ce92f6b7ea6a5eb994b9408038e595 Mon Sep 17 00:00:00 2001
From: fritsch <Peter.Fruehberger@gmail.com>

Subject: [PATCH 01/15] Formats: Add support for DTS-HD HR (High Resolution)
 Audio

Modern AVRs don't accepts DTS-HD HR when encapsulated in a 192 khz / 8
bandwidth stream. Therefore send this format as 192 khz / 2.

Update:
I took @ford-prefect patches and additionally added mine on top to distinguish between DTSHD and DTSHD-HR.

TrueHD: Multi-Channel opens including noise
DTS-HD-MA: Multi-Channel opens including noise
DTS-HD-HR: Properly opens 2 channel / 192 khz and dts-hd-hr

As I am not sure at all if my laptop's HDMI connection actually supports DTS-HD-MA / TrueHD - I keep it as is for now :-)

Await @MilhouseVH tests

DTSHD Log, looks quite okay I'd say (though, only noise on my system)

Thanks @Rechi - I only fixed new code. Will sort the rest after we know which version this is stable in upstream PA and fine from semantics.

fritsch · 2019-10-04T11:52:22Z

@ford-prefect I had a lookg into pulse's alsa sink implementation. It seems there is a lot signalling still missing: AES0, AES1, AES2, AES3, etc. I don't think setting AES0=0x06 is enough

See: https://github.com/xbmc/xbmc/blob/master/xbmc/cores/AudioEngine/Sinks/AESinkALSA.cpp#L456

How did you test DTSHD / TrueHD - is there some sample application, e.g. pacat that succesfully works?

phunkyfish · 2020-03-09T15:31:51Z

@fritsch how is this progressing? Is it active or would you like to put it on the the backburner?

ford-prefect · 2022-01-15T00:30:30Z

I've started working on the PA bits for this again, so please let me know what I can do to help move this forwards. ~~My installation of Kodi (19.2 from Fedora) seems to not output TrueHD at all.~~ I guess I need to build this branch for testing first.

fritsch · 2022-01-15T06:16:28Z

Awesome to see. I rebased and squashed the changes. Some of the ifdefs / version handling will need adjustment as they still focus towards version 13.

ford-prefect · 2022-01-18T17:48:07Z

The PulseAudio branch should be good for testing against XBMC (I've implemented the AES bits as well).

As I am not sure at all if my laptop's HDMI connection actually supports DTS-HD-MA / TrueHD - I keep it as is for now :-)

I think I am also hitting this problem, so not sure how best to test this tbh.

fritsch · 2022-01-18T19:44:02Z

You could start kodi like this: KODI_AE_SINK=ALSA kodi - that way it will use ALSA instead of pulseaudio - and you can see if TrueHD / DTS-HD is available under the expert audio settings?

ford-prefect · 2022-01-18T20:06:30Z

It is available, but does not work. Ditto for trying this with mpv, so it really seems like an issue with my setup. What I tested:

✅ speaker-test with 2ch
✅ speaker-test with 8ch
✅ EAC3 audio with ALSA
✅ DTS-MA-HR audio with ALSA
❌ TrueHD with ALSA
❌ DTS-HD with ALSA
✅ EAC3 audio with PulseAudio
❌ TrueHD with PulseAudio
❌ DTS-HD with PulseAudio
❌ DTS-MA-HR audio with PulseAudio (expected based on your patch above, but let's punt this one for now)
