ok, when i play musik or "normal" encodet movies and look with "o" the status bar, everything with mp3 in front is playing, but when i try to play a DVD there is "ac3" in front, or "dts" and both are not playing.
even with stereo there is "ac3" in front, and also not playing... maybe is there a codec missing??

pico, do you really need a full jaunty installation, especially the 64bit version?
I would recommend downloading the XBMC live distribution, burn to CD and boot, and see if, with the same settings, you can get multichannel via HDMI.

i don't need a full installation, but it shouldn't be normaly a big problem to get something like sound to work...

one more info, if i disable ac3 in xbmc settings, the stereo output works in dvd's but still no dts...

I also have this problem. Same motherboard.
After installing xbmcLive 9.04.1 all sound stopped working. When I had the 8.10 everything worked fine.

I use Jaunty as well, but 32bit, other then that i have the same setup as you.
Did you remove (or move) any .asoundrc or asound.conf files?

@Musta78

have you updated alsa to recent version? 1.0.20?

@mlmc
after installing alsa 1.0.20 i removed .asoundrc file
what device have you in xbmc settings for passthrough device?

hdmi, as mentioned in the post before.

[pico]

and dts is working for you? or something else with 5.1 output via hdmi?

Yes, AC3 and DTS media is being passed through to my receiver. The receiver displays Dolby Digital (AC3) or DTS when being fed.

what really confusing is to me, that i have stereo sound if i disable ac3 in settings of xbmc, and i dont have stereo sound with dvd when i enable ac3...

when i am at home later, i will try an external player for this...

[xbmcuser01]

[...] will try an external player for this...

You might try:

Code:

cd /media/cdrom
mplayer -dvd-device ./VIDEO_TS/ dvd:// -afm hwac3

(mind that Linux is cApItOls sensitive) This plays my DVD w/ DD 5.1, and the audio part is digitally streamed to my Amplifier. Then, if you watch the babble that mplayer spits out on the command line, you might see what the Audio Id (aid) of the DTS stream is. Then you can (this example is for Gladiator):

Code:

mplayer -dvd-device ./VIDEO_TS/ dvd:// -afm hwac3 -aid 137

Which plays the 3/2 DTS stream and streams the DTS audio part of the DVD undecoded (i.e. digitally) to my DTS/DD amplifier. Does this do anything for you?

P.S. I noticed that you suspect alsa of some sort of incompatibility. You might want to try to start your PC w/ a Knoppix CD. Maybe that has a different version of alsa that does work for you... Hope you solve the problem.

If you soundcard refuses to passthrough digital audio streams (i.e. 44.1 kHz PCM for audio-CD's, DD or DTS for DVD's etc.) then that is not so strange. If you tell XbMc not to stream AC3 to your receiver then Xbmc downmixes DD5.1 or DTS 3/2 to (analogue) stereo. And if you tell Xbmc to not touch the AC3 (DD5.1) stream and send it to your soundcard then you're in trouble I still think your soundcard is not configured to passthrough digital audio. It may be alsa....

P.S. I had an old Creative labs Soundblaster card which also did not work w/ DTS. That is because Soundblasters upsample digital signals that are 44.1 kHz (i.e. CD's and sometimes DTS) to 48 kHz. But that'sanother story, first try to pass through Dolby Digital. Good luck
