xbmc-standalone. How to?

[kenpuu]

Hello.

First at all, great work! I'm impressed with the result of spotyxbmc.

I hope it's the right side to post my problem. I installed spotyxbmc two days ago, but I've been trying to execute xbmc without desktop, and there's my problem. I'm a newbie in linux, so I need some help.

I've got two pcs, and in both I execute 'xinit xbmc-standalone'.

In one (atom 330 with nvidia ion) the only problem is that there's no sound, but the rest seems to be perfect.
In the other (core 2 duo with an x-fi xtreme audio pci-e <<for those alsa drivers, I need to compile the alsa-snapshot>> and a graphic card ati 4770) I also haven't sound but it is very laggy.

I think the problem is the modules loaded, because if I execute xbmc inside gnome it runs perfectly. Any suggestion? Thanks in advance.
