No sound problem in Enemy Territory

I've been fighting a problem with no sound in ET...I am running PCLinuxOS
On another Linux forum, someone gave me this solution:

"I dont know PCLinuxOS package management but make sure you have alsa installed and alsa-oss support then simply run following:

modprobe snd_pcm_oss"


How do I "run the following: modprobe snd_pcm_oss" ?
Do I type that into the module.conf file in my /etc/ dir? I tried typing it into a terminal, but it is not a recognized command.

you have to be root or sudo and you type it in a terminal.

Oh I see. Thank you.
I did it as root, but still no sound.

yup no sound here either in ET

Strange, I have never had any problems with sound in ET.
