How do you setup your new drivers for you motherboard, Gigabyte GA-EP45-UD3LR, in Linux or Ubuntu?

What drivers do you need? Usually your Ubuntu will load all the drivers automatically and you should not need to worry about it.

How comes then I don't have any sound coming out.I had a disk that came with the Motherboard for WinXP or VISTA but how do I use it when I have Ubuntu setup on it?

Find your audio controller name and let us know. You can do it either from linux or windows

What distribution are you using? You probably need to tell more. What application? You might not have alsa configured.

That is what I have. I hear the sound through headphones but not my speakers and I know I have the Jack plugs right in the back off the motherboard.

If you can listen to something from headphones, there is nothing wrong with the drivers. Where do you connect the headphones? And where do you connect the speakers? Disconnect the headphones before connecting the speakers and then see if you can hear something.

Did that give you any info that you wanted on my sound card?

So its not an issue with the sound driver. Did you try plugging both speakers and headphone in the exact same jack?

How do you configure Alsa that you mentioned?

No I didn't. I am not even sure what all the Jacks are for. There is 8 jack holes and I know that 2 of them are for the headphone and Microphone. Which of the others I don't get any sound from them at all.

In some of the machines like one I have, there are jack ports in the front and back. But if I connect headphones in the front, I wont have any sound from the speakers connected in the back.

Mine are all in the back. Well, I am going to bed. Maybe later at wizzo49@yahoo.com if any answers. Thanks

The green one's for the speakers

Well, if you are not even sure you plugged the speakers in the right place there's not much else to look at until you do so.

Secondly, unplug the headphones while testing. As has already been said, some combinations will disable any other output when the headphones are plugged.

Third, and very important, use alsamixer or any other mixer program to make sure that all the levers are up and non-muted.

As has already been said, there's nothing wrong with your drivers if you can hear any sound in your headphones. Also, forget about the cdrom that came with your motherboard. 99% of the manufacturers never put anything for linux on that cdrom. That's windows-only stuff most of the times.
