No sound on Ubuntu install.

[KingTarkata]

Well, as the title says, I've installed Ubuntu on this computer, (HP slimline s7727c), and so far everything but the sound has worked out fine. The graphics, wireless networking, and everything else is pretty much flawless.

The sound, however, has not. Multiple updates hasn't helped, and the driver updater doesn't yield any results. I've tried using the audio tool through the terminal, (Not sure what it was called, but it allows me to change volume levels for certain things, something that came with the apparent driver set), and it didn't do anything. The dB level is at 0.00 when the volume is 100%, and goes to -100.0 when the volume is muted, which to me makes no sense.

The sound card, (Or so I've found from research), is the HD Realtek ALC888. I'm not really sure what I should look for or how to fix this as I am new to Ubuntu.

Thanks for the help, hopefully someone will actually reply this time.

What version of Ubuntu? That's very important.

[QUOTE=Yeojsav;20866686]What version of Ubuntu? That's very important.[/QUOTE]
I believe it's Ubuntu 9.10, (Or something similar), amd64.

[Yeojsav]

If it's 9.10 uninstall it and then re-install it.

then type uname -a and post the output.

A ton of people have issues with the MCP51 audio chipset.

Try this:

$ sudo apt-get install linux-ubuntu-modules-2.6.31-20-generic
$ sudo modprobe snd-hda-intel
$ aplay -l
$ asoundconf list
$ asoundconf set-default-card NVidia

[KingTarkata]

On the first command I get: Couldn't find package linux-ubuntu-modules-2.6.31-20-generic

[butre]

I remember it's linux-ubuntu-modules- and then something about the kernel. I haven't used Ubuntu in a while, so I don't remember the exact package name.

try this one

 apt-cache search linux-ubuntu-modules

and post the output.

[KingTarkata]

linux-wlan-ng - utilities for wireless prism2 cards
aufs-source - Source for the aufs driver
linux-wlan-ng-source - linux-wlan-ng driver
lirc-modules-source - infra-red remote control support - kernel modules
lms - OpenAMT Local Manageability Service

[butre]

Well hell that package might not be in there anymore.

[KingTarkata]

Well, the second command works, (Or when I enter: $ sudo modprobe snd-hda-intel, no errors occur). The rest of the commands don't work because asoundconf is undefined, and isn't recognized.

[KingTarkata]

Well, the update manager just installed something similar to what those commands entitled, so we'll see where that goes.

[B]EDIT: [/B]Woops, double post. Still nothing though. Anyone got any ideas?

[GoblinTHC]

Take a look around the ubuntu software center, might be something in there...

[KingTarkata]

Nothing in the software center, any more help? I've been looking on Ubuntu support forums for a while, and nothing has worked yet.

[Cuel]

google the name of your audio chipset and look for someone who's had similar problems. I did this with my HP Pavilion dv2, took some time but I finally got it working.

Have you tried clicking the speaker sign i nthe top right? that was my problem :(
