Ubuntu question: no modprobe.conf??......

i'm setting up Ubuntu on my desktop and all is going pretty well overall.

right now i'm trying to get the nForce audio driver installed. the sound works with the default alsa driver, but i can't figure out how to enable surround. i figure getting nvaudio and nvmixer installed might help.

however, the directions here want me to edit the modprobe.conf as usual, but Ubuntu doesn't seem to have one. nor does it have a conf.modprobe or modules.conf or anything that resembles the configuration file i need.

in the modprobe.d folder, mentioned in the directions, there is a file called "aliases" that has a bunch of (go figure) aliases in it, but none of them are for sounds modules.

i'm hoping someone has some experience with Ubuntu modules and can point me in the right direction.

i've seen that some ppl think the alsa drivers are actually better than th nvidia ones, so if anyone is familiar with alsa and cn tell me how to get 5.1 working that would work too

Add file /etc/modprobe.d/<modulename>.modprobe and add options there (man modprobe.conf).
After that 'sudo update-modules' and /etc/modules.conf will be created.

i think Ubuntu just has a weird system, and i think i figured it out. in the modprope.d directory there's a file called "blacklist" where i can list modules i don't want starting.

i actually got the nVidia sound driver installed correctly, i think, but when i start up nvmixer from the console, it pops up but the console gives a "BadDevice" error message, and not all of the options in nvmixer work properly.

is anyone familiar with what a badDevice error means? i suspected maybe there was some funny business going on in my xorg, but there's nothing about sound in it.

i started over from scratch to see if i could just get alsa to run surround sound, but the best i can get it to do is play the front two channels through the back. so its running a fake 4.1, but i want 5.1 -- my center channel doesn't play.

so if anyone knows some alsa 5.1 tweaks i'm up for that too.

i'll try the nvidia driver again maybe and see if i can recreate that error message i full...

figured out how to get rid of the error messages. there's a section in the xorg for wacom tablets, or tablet PCs, or both, and it fucks with just about every GUI started from a console.

but now it doesn't appear that nvmixer has any effect on the speaker setup.


btw, anyone know how i can switch Ubuntu from using alsa to OSS?
