No success with th via82xx sound module. In the BIOS there's no option 
like sound emulation. I know that for the previous ebox 2300 model, 
someone compiled a driver called sis_7019. I guess I will have to 
compile a driver for the ebox 2500 myself, but I can't find source code.

I also found a script on the ltsp-website that modifies the 
/opt/ltsp/i386/etc/rc.sound script, so that alsa drivers can be used 
through esd. With these modifications made, I specify the snd-hda-intel 
module, and it seems to work fine. I can telnet the client on 16001, no 
more errors like "/dev/dsp no such file or device", testing sound in GUI 
shows no errors. BUT ... no sound coming from the speakers
