No Sound in Ubuntu 10.04

I have an alienware laptop and I've decided to use Ubuntu on it. When I installed Lucid Lynx the sound does not work. Yet when I wiped the drive and installed Jaunty Jackalope the sound DOES work. No hardware has been changed and the only software change was using an earlier version of Ubuntu.

After reading most articles about the issue, I've made sure nothing is muted in alsamixer and I've turned the volume all the way up. My group has audio permissions. Even the instructions at http://www.unixmen.com/linux-tutoria...0-karmic-koala seemed promising (despite the link name, it has information applicable to Lucid Lynx 10.04) but it didn't work.

When I go to System -> Preferences -> Sound and look at the Hardware tab it doesn't list anything at all. When I did aplay -l it gave me this information

Code:

card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem]

Subdevices: 1/1

Subdevice #0: subdevice #0

Yet alsamixer says I have a RealTek ALC880.

I'd really like to get my sound working on my computer.

That's the name of the chip.
What's the output of this command?

Code:

lspci -knn

And this one too.

Code:

lsmod |grep snd

jdk

Just trying to be a completist.

Code:

Well it all looks perfectly normal to me. Have you got the pcm and volume levels up on your alsa mixer (not just the volume but the pcm must be up too)? The driver looks correct and is loaded.
jdk

I opened alsamixer and they're all at 100% for output/volume/etc.

Thing is that when I did aplay -l using Jaunty Jackal it listed the modem (like in my prior post) but got this information in addition to the modem.

Code:

card 0 Intel [HDA Intel], device 0: ALC 880 Analog [ALC880 Analog]

Subdevices = 1/1

Subdevice #0: subdevice #0

card 1: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

If you can just tell me how to get Ubuntu to stop nagging me about updating stuff I'll be happy as a clam. The closest option was every two weeks. Still I'd like to use something that's up-to-date where my sound works rather than having a mute computer.

It looks like your multimedia setting in gnome (I assume your using gnome) is pointing to the wrong device. Go into your system settings and change them to point to this device 0 Alc analog...
My aplay gives me this

Code:

card 0: SB [HDA ATI SB], device 0: ALC887 Analog [ALC887 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

I don't use Ubuntu so I don't really know. I have a package called update-notifier-kde. Maybe you have something like update-notifier-gnome. If so just remove it and problem solved.

How would I go about doing that? Would you kindly point me to the relevant man page or tutorial online?

As I said, I don't run ubuntu nor gnome. Isn't there a systemsetting app? and doesn't it contain a category "multimedia"? I would guess it would be there. Otherwise try man alsamixer or man alsactl.
