Sorry for being stupid, but could someone explain to me how this is supposed to work?
I have an nvida gtx 260 card with HDMI out connected to my receiver.
I compiled pulseaudio with latest patch from this thread, audiofilter and xbmc from cbxbiker61's github links.
PA Passthrough using VLC works out of the box and regular audio plays like it should.
In XBMC I choose System -> Settings -> System -> Audio Output, and there I have the following choices:
Audio output: [HDMI, Optical/Coax, Analog]
Audio output device: [hdmi (ALSA), iec958 (ALSA), Defaults (ALSA), Internal Audio Digital Stereo (IEC958) (PulseAudio), Defaults (PulseAudio), Custom]
Passthrough device: [hdmi (ALSA), iec958 (ALSA), Custom)]
I guess I'm supposed to have the hdmi-surround-71 device? It doesn't work if I type it in manually using "Custom".
My PA_PROTOCOL_VERSION is 23.
Running Arch linux on 64bit
Greatful for any help regarding this.
BTW, I can get passthrough working through ALSA with PA killed

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 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.
