Hi guys !

I got a strange problem with xbmc (10.00svn version from ppa) and alsa (1.0.24) on 11.04 (but i had the same on 10.10).

Indeed, I can play with xbmc mp3, video with mp3, with "dolby digital" content and dvd, but no video with "ac3" content (no sound, the image works).

I can read the file with vlc or media player on the same machine.

Could someone have a clue for me ?

Here are some info:

htpc@htpc:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
Subdevices: 1/1

Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0

and the error in the log:

21:35:30 T:2165234544 M:1591422976 DEBUG: Initialize - using alsa device iec958:CARD=Intel
21:35:30 T:2165234544 M:1591422976 ERROR: Initialize - hw_params_set_channels, alsa error: -22 - Invalid argument

Thanks in advance !!

Sorry, my mistake, that's the error I got with pulseaudio..
I removed it and now here's the correct log: http://pastebin.com/LVhmSBvX

What are your audio settings? It's opening the iec958 device (spdif) with 6 channels in pcm mode, spdif only supports two channels unless you're using passthrough.

Hi bobo1on1,
what do you mean by audio settings ? in xmbc ? both device (audio and passthrough) are set to iec958

[bobo1on1]

You have to set audio output to Optical/Coax for spdif to work correctly.

That is already done , works with other ac3 files

During playback, turn off "Output stereo to all speakers" then restart the video.
