View Full Version : [ubuntu] Asrock ION no (multichannel) SPDIF sound in XBMC (Ubuntu 9.04 Jaunty)

September 22nd, 2009, 10:30 AM
Hardware: Asrock ION 330 (DVD)
BIOS: 1.60
OS: Ubuntu Jaunty (9.04)
Display drivers: 185.18.36
Alsa drivers: 1.0.21

First things first, I want multichannel audio (AC3/DTS) over SPDIF in XBMC (via HDMI isnít necessary). Before I started with my days of struggle through xbmc and linux threads (yes Iím a linux noob), I had sound over SPDIF in XBMC but as so many unfortunately only 2-channel (http://ubuntuforums.org/showthread.php?t=1212523). Now after my hellish search I lost my SPDIF sound, but only in video files which are played by XBMC.

This was after my last try to disable pulseaudio by this post: http://idyllictux.wordpress.com/2009/04/21/ubuntu-904-jaunty-keeping-the-beast-pulseaudio-at-bay/
All my tries with /etc/asound.conf and ~/.asoundrc didnít work so I removed the files but unfortunately no luck. If Iím getting sound back in video files I still think itís only in 2-channel stereo. Before disabling PulseAudio I had the strange thing that my amp thought it received a 2-channel stream but itís was in fact a 5.1 channel stream but only played over my L and R speaker. I can tell you, it sounds very strange ;-)

Does someone have an idea because Iím clueless at this point. Help much appreciated!

UPDATE: closing thread after a 3rd clean Ubuntu Jaunty install and replies (or lack off replies) to just clean install Ubuntu Jaunty again (on other forums).

For the people with the same crappy problem, I tested in Windows 7 today and everything works like a charm without even installing extra display and/or sound drivers: full HD display and DD5.1+DTS sound over SPDIF and/or HDMI.

Why is this such a problem within the latest Ubuntu version. Unbelievable!

Hi OobieDoob!

Iīve had the same problems with my ION330 since 9.04 released. No help in sight it seems. Iīve pretty much abandoned my Ubuntu partition since then... :(
