XBMC PulseAudio passthrough support (including Nvidia) is available

cbxbiker61, you did it!!! Excellent work on the DTS-HD MA!! Big Thank You.

I understand Dolby TrueHD is still a work in progress. Waiting with anticipation.

I'm on Ubuntu 11.10 64-bit and was able to watch the blu-ray Rise of the Planet of the Apes in DTS-HD MA 5.1 on xbmc with the plugin plugin.makemkvbluray.zip and MakeMKV streaming in the background.

I have an NVidia GTX 560Ti and using a probe_mask.

It played flawlessly and the whole time DTS-HD MSTR was showing on my receiver.

I ran into several make,compile errors along the way, but through googling solved them all.

Here's what I did. For the most part, I followed shadow's script from post# 41:

1)PATCH PULSEAUDIO

Got the patch, saved as patchfile and put inside pulseaudio folder
In patchfile, added a space in front of lines 4,5,13,18 to clear the malformed errors.
Typo in patchfile in line 18, it's incomplete, through googling completed with what is most likely:
@@ -3700,7 +3700,8 @@ static int mapping_verify(pa_alsa_mapping *m, const pa_channel_map *bonus) {

Then patched with:

2)INSTALL JSONC LIBRARY

SATISFY PULSEAUDIO AND XBMC DEPENDENCIES, DOWNLOAD FILES

3)INSTALL PULSEAUDIO

At that point got error:
E: [pulseaudio] main.c: Failed to kill daemon: No such process

lauched command:
./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/.libs/

Got about a dozen errors, mostly org.freedesktop.DBus.Error, unable to contact D-Bus session.

Could not get pulseaudio started, no sound devices in Ubuntu's System Settings → sounds

Skipped and continued on

4)INSTALL AUDIOFILTER
lots of googling here. I'm on a 64-bit system, but building/compiling in 32-bit.

To clear the missing bits/predefs.h error, and for proper 32-bit libc includes on a 64-bit system:

To tell g++ to take the 32-bit directory insteady of the 64-bit one and to clear error: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.6.1/libstdc++

Then continued with:

5) INSTALL XBMC

After running this last make command, magically all pulseaudio problems from previously got fixed and the Digital Surround 7.1 HDMI output appeared in Ubuntu's System Settings → Sounds.

EDIT: on my Ubuntu 64-bit, launching xbmc from the shortcut doesn't work. But doing sudo xbmc from terminal works perfect each time.

Confirmed that DTS-HD MSTR is still working on Ubuntu 12.04 with PulseAudio 2.0

The only thing still missing is Dolby TrueHD support.

I did a clean install of Ubuntu 12.04 32-bit.

I downloaded, compiled and installed audiofilter and xbmc from cbxbiker61's git repository. I did not modify PulseAudio or install the jsonc libraries.

Still works the same as on Ubuntu 11.10 by selecting Digital Surround 5.1 PulseAudio
Or by disabling PulseAudio with:
And selecting HDMI Nvidia Alsa

You know that the main master git repo build supports all formats now, and has supprt for pass through options similar to cxbikers build?

Including True HD, DTS MA, DTS HRA etc....

Thanks for the great tip.

I went and compiled from the main master git repo. Indeed, Dolby Digital+, TrueHD and DTS-HD MSTR are supported. I can even select my receiver by model name as an output device. Impressive. Development has come a long way.
