Demo: No sound

[Bef]

Hello,
I don't hear any sound in the demo on my Ubuntu 8.04 using Pulseaudio. Sound is working with all other installed applications.

Here some information about my system. Please tell me what additional information you need if this isn't enough.

uname -r: 2.6.24-16-rt

cat /proc/asound/cards:
0 [T71Space ]: Aureon71 - Terratec Aureon 7.1-Space
Terratec Aureon 7.1-Space at 0xb400, irq 21
1 [V8237 ]: VIA8237 - VIA 8237
VIA 8237 with AD1980 at 0x1000, irq 22


I think it might be a problem with openal. I have made some changes on the openalrc file so it should use Pulseaudio... but I'm not sure if everything is set up correctly now or if I have to change something else.

cat /etc/openalrc
(define devices '(esd))

Here are some messages from the logfile related to my problem:

Can anybody help please?
