Yes. The thread should probably be renamed. I initially modified the AudioFilter code to allow me to get PulseAudio pass-through working. At that point I wasn't really testing any configuration besides my PulseAudio config. Some of the other guys in this thread have been testing it with straight Alsa with success. I haven't heard any complaints that are specific to running it with Alsa.
I haven't looked at how the Windows driver's interact with pass-through, but there is the possibility that it would run there too. I don't have any Windows boxes around, so I can't personally test that code anyway. AudioFilter should compile on Windows with some jiggering of the Windows build files. I did move some source files around, so I'm pretty sure it needs to have the build files fixed. Any patches for that would be appreciated.

Good to know I´ll give it a try next week and report. Thanks again cbxbiker61 and great job...

cbxbiker61; it looks like you have done it. Have tried a number of movies and did not encounter a single problem; thanks!
Looking forward to your TrueHD passtrough implementation :-)

I'm trying to put together what needs to be done to get this working, but I'm lost.
I need pre-Eden to get BD ISO support.
Can I also get HD audio passthrough using your filter? If so, can you update the original post, or post here a dummy's guide on how to do it?
Thanks in advance!

If I'm not mistaken pre-Eden means git head, my repository follow git head, so you should be fine there.
If you've got a receiver attached through hdmi, you should be good to go on pass-through.
Well I'm not quite sure what a "dummy" wants to know besides what's in the first post. If you know how to use compilers and git, you should be able to do it. If you have specific questions, I'm sure someone can answer those.
I'll take another look at the first post, maybe I'll add something there. Keep in mind the Developer section is mostly for advanced users and other users that want to know what might be in the pipeline.
BTW, it's traditional for the README in the repositories to explain what's necessary for compiling the code. So maybe that's what you want to look at.

As promised last week:
Zotac ID41 (ION2)
Debian testing minimal (fresh install)
XBMC compiled with external ffmpeg support and PA disabled
PA not installed in the system
Just had to figure out which custom device name to use as hdmi audio device cos hw:0,7 (the usual one) didn't work for hd bitstreaming (dolby and dts were ok). So I tried hdmi:CARD=NVidia,DEV=1 and then DTS-HD MSTR flashed in my Onkyo Receiver.
Thank you very much and keep up the great work, cbxbiker61.
Waiting for Dolby True-HD implementation to test it
PD: The few files I tested played without any problems (no slutter...)

That's true in windows. I think it's because of the protected audio path and DRM but Linux in an other different world.
I can confirm it's working and there are more references throuh the web (http://www.mythtv.org/wiki/User_Manual:HDAudioPassthrough)
Repo updates in prep for true-hd support - cbxbiker61 - 2011-12-02 11:07
I just updated the AudioFilter and Xbmc repositories. I cleaned up the AudioFilter code and added the ability to the AudioFilter code to strip dts-core out of dts-hd streams (this could be used in the future to do pass-through with receiver/hdmi card combinations that cannot support the full bandwidth required for dts-hd). As of right now the xbmc side has been written to tell AudioFilter that it supports the higher bandwidth necessary for dts-hd. If anyone runs into a receiver/hdmi card that this isn't true, post the output from "cat /proc/asound/card*/eld*". I'm actually quite interested in what the ati cards will list for support in their eld's.
The good news is now that I've cleaned up the AudioFilter code and added all the bells and whistles I wanted for dts-hd, I'll be working on the dolby true-hd support starting tomorrow. Hehe, I just bought the 6 original Star Trek movies, and they're all in true-hd 7.1.

Some SD DD5.1 movies (they still exist) no longer want to play correctly: the frame rate drops from 25fps to 4fps. The same content plays correctly in the current XBMC nightly, so there might be a little error somewhere in Audiofilter.
