oops, guess i broke my sound driver :(

yesterday i found a sound driver on realteks site, so i thought i would give it a shot but it doesnt seem to work, now i would either like to get back the old one i had (dont know how to do that) or fix this realtek one...

this is what the realtek driver install said, apparently it thinks the install was a success, but it wasnt

Code:

Building card database..

























Running update-modules...
Setting default volumes...
amixer: Mixer attach default error: No such device
Saving the mixer setup used for this in /etc/asound.state.
/usr/sbin/alsactl: save_state:1253: No soundcards found...




















===============================================================================

 Now ALSA is ready to use.
 For adjustment of volumes, use your favorite mixer.

 Have a lot of fun!

 

Have you looked at the main volume in the mixer?

 

by mixer you mean the volume thing on the panel right? and when i hit the volume up/down buttons the volume wont change, it is all the way down and i cannot change it anyway i try. When i double click on it i get a little popup that says:

Code:

No volume control GStreamer plugins and/or devices found.

i am trying to install an alsa driver i found, but in the install it says:

Code:

7) Edit your kernel module config (either /etc/modprobe.conf or
   /etc/modules.conf, depending on the kernel version). If you are not
   sure, what to do, you may try the alsaconf script available in
   the alsa-utils package.

8) Run 'modprobe snd-xxxx' where xxxx is the name of your card.
   Note: All ALSA ISA drivers support ISA PnP natively, so you don't need
         isapnptools any more.  Don't use both together.  It will
         conflict.  For disabling the ALSA ISA PnP support, specify
         --with-isapnp=no configure switch.

any idea what i should do for these?

 

Try sudo apt-get install linux-backports-modules in a terminal and reboot.

 

that gave me this:

Code:

cleippi@Christopher-PC:~$ sudo apt-get install linux-backport-modules
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Couldn't find package linux-backport-modules

 

Go to System --> Admin --> Software sources and enable all repositories.

 

i do believe they are, you are talking about the multiverse, restricted, universe, and main right?

 

Yes, and look under the Updates tab.

 

what do i need under the updates tab?

 

Where are the check marks?

 

Important security updates
Recommended updates

Check for updates: [Daily]

those three things have checkmarks beside them under the updates tab, and under the Ubuntu Software tab i have all the main, universe, restricted, and multiverse all checked off

 

Try to put a check mark beside Backports.

 

still the same error..

but, i think i have another alsa driver almost installed, i just got to these steps and i dont know what to do now...

Code:

7) Edit your kernel module config (either /etc/modprobe.conf or
   /etc/modules.conf, depending on the kernel version). If you are not
   sure, what to do, you may try the alsaconf script available in
   the alsa-utils package.

8) Run 'modprobe snd-xxxx' where xxxx is the name of your card.
   Note: All ALSA ISA drivers support ISA PnP natively, so you don't need
         isapnptools any more.  Don't use both together.  It will
         conflict.  For disabling the ALSA ISA PnP support, specify
         --with-isapnp=no configure switch.

for step 7 i cannot locate the alsaconf script or /etc/modprobe.conf or /etc/modules.conf and i dont know how to find hte name of my sound card either (for step 8)

 

Open the Update manager, reload the sources and update your system.

 

ok, i did, but im still getting the same error.

by reload the sources you mean click the 'check' button right?

 

Yes...you've updated everything?

 

everything it found i updated

 

Open Synaptic package manager and search for a package called linux-backports-modules

 

well, sound works now, thx

 

It was my mistake the first time because I said:

I forgot the "s"
