Hi guys
I've set up the audio of my Intel Atom + nVidia ION2 system (Sapphire HD2) following this istructions:

http://wiki.xbmc.org/index.php?title=HOW...,_or_GT240

Now I have passthrough audio ok, decoded audio ok, but no audio in xbmc menu
What should I check to start the investigation of the problem?
I have pulse-audio and ppa xbmc version 11.0 with pulse-audio support
Bye

Do you have sound in the desktop session working for the same user?

[Menion2k]

I don't have any windows manager, since (sorry to haven't stated it) I've used ubuntu minimal CD for the Linux base.
I'll try to test in CLI.
Shall I aim to pulseaudio enviroment, right? Anything special I should start from?
Bye

Hi
It seems that the istructions are failing for the pulseaudio part, in syslog I read

Apr 25 09:57:55 MenionXBMC pulseaudio[1136]: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device=hw:1,3"): initialization failed.

and then the module failed to load.
I've removed from /etc/pulse/default.pa the suggested line load-module module-alsa-sink device=hw:1,3 and now the daemon loads with udev probing.
This is the pacmd output

2 sink(s) available.

it seems that pulseaudio wants to load module-alsa-card instead. However I did some test with alsa.
I get some problem in having the output, even in analog. For example "speaker-test" gives me the following:

ALSA lib pcm_dmix.c:1018snd_pcm_dmix_open) unable to open slave
Errore di riproduzione: -2,File o directory non esistente

So I started again from aplay -l

Sorry for the italian, but it says that the nVidia HDA is the board 1, with devices 0,3,5,7,9
So I modified the asound.conf like this

pcm.!default {
type plug
slave {
pcm "hw:1,3"
rate 48000
}
}

Still no sound. Then I played around with speaker-test -Dplughw:1,x, with x=0,3,5,7,9 and I've endup in the fact that I had output with 9!!!!
So I set 9 in the asound.conf and I got sound! There is another thing, that it's really obscure to me: why for the video playback I have to stay with device 3? If I set it to 9 I get "unable to open device", I guess because pulseaudio owns it.
By the way: solved!
