Nice! This is fantastic news, I'll have to try it out!

TrueHD not working for me - nicob - 2011-04-20 19:24
No luck for me...
I tried 3 Bluray movies with TrueHD track:
Heat (crashed xbmc): http://paste.kde.org/15067/
Let me in (kind of fast forwards without audio): http://paste.kde.org/15079/
Dolby.The.Sound.Of.High.Definition.Blu-ray.2007.1080i.AVC.TrueHD7.1 (same as let me in): http://paste.kde.org/15103/
I noticed in the logs that it stated that TrueHD passthru was disabled, this is definitely not the case!
I know my setup is more than TrueHD capable, at least, it was when I runned Windows
Normal DTS and Dolby D are playing fine with the new AE. (although normal music playback doesn't work for me either)

I can confirm the same problems as nicob with a git build on Ubuntu (10.10) today.
Not only does TrueHD not work, but I get movie speedup and no sound on all videos.
If you think it would be useful I could provide logs.

I tried 3 Blu-ray so far, played the movie entirely without any problem, will cycle through my entire collection to be sure (have a few).
Nicob: I saw you use VAAPI, I assume u have an ATI? Have you checked if ALSA HBR passthrough is supported on it? IIRC Anssi mentioned it wouldn't work on some ATI models (yet?).
- gnif - 2011-04-21 04:58
@lloydsmart ,@nicob - I bet you have an ATI HDMI card... the problem is that TrueHD requires 8 channel output to get the required bandwidth, most ATI cards can not yet do > 2.0 channel output via HDMI. Your log shows that it failed to open the audio output with the required number of channels.
As for the crash, it might be related to the change I made to open the extra channels, I will investigate this, but I really need a crash log as it has a back trace attached to it.

Your log shows that it failed to open the audio output with the required number of channels.You will lose that bet.... (VAAPI is not always ATI) I have an Intel Sandy Bridge (H67)...
I will send you the crash log... in about 9 hours (when I am done working) and I have to recompile, as I normally compile with --disable-debug...

I have an H67 express = CougarPoint so it should be supported... But I will check the EDID when I am home....
- gnif - 2011-04-21 10:08
@nicob, well your playback issues are because your HDMI output does not support > 2.0 output as your log clearly shows, but I am indeed interested in the crash, it should not have happened even so.

I have an Nvidia GT430, connected to an Onkyo 705 via HDMI.
- nicob - 2011-04-21 18:39
@lloydsmart: Good to know I am not the only one! (I probably would have given up) BTW I also have an Onkyo (NR-3007)

Here is the gdb backtrace: http://paste.kde.org/17227/
And I am sorry but I do have 5.1 HDMI output when playing a movie with DTS or AC3 with your AE branch.... (my onkyo says it gets 5.1 from the HDMI input)
also, I have the HBR:
cat /proc/asound/card0/codec#3: http://paste.kde.org/17317/
Found the possible problem, the edid information is incorrect on CougarPoint
http://forum.xbmc.org/showthread.php?tid=96669 Wrote:Multichannel lpcm does not work at the moment. It is some kind of EDID parsing problem with alsa. Maybe with your setup it can work. At my setup it detects my TV's available sound modes which are limited to 2 channel 88200hz although my AV receiver supports 8 channels up to 192khz. Strange is that sometimes EDID detection completely fails and that way i have all the modes supported. :-) I already contacted the developer at project Alsa.
Man that sucks!
