No sound from laptop speakers

Asked by nimy on 2005-10-23

I have an old (Compaq Presario 1200) laptop with a VIA82C686 AC97 multimedia audio controller. My built-in speakers were working under the original Windows ME, but since I wiped out the hard drive to install ubuntu (warty warthog or hoary hedgehog) they don't work. I've looked thru ubuntu's support pages, but nothing helps. Before giving up, I would like to know how to determine whether it's the AC driver, or whether the speakers have a bad connection or other hardware-related malfunction. I get no error output and no sound at all, although the AC is recognized. I have no jacks with which to connect external speakers, so I have to rule out that option.

Hello, first please go to Applications -> System Tools -> Ubuntu Device Database and fill out the forms so that the Ubuntu developers know that your soundchip is not working and that they can fix it in the next release.

Then go to Applications -> Accesorries -> Terminal and type the following things:

sudo modprobe via82cxxx_audio
[ENTER] [type your password, there won't be any output like * while typing your password)
sudo modprobe snd-via82xx
[ENTER]

If there is no output at all everything worked well. If there is output, please post it here.

Then test if your sound now works correctly (do not restart, just relogin for example).

If it does not, please read this: https://wiki.ubuntu.com/DebuggingSoundProblems

If it does please type

sudo gedit /etc/modules

in a Terminal and add the following lines to the file:

via82cxxx_audio
snd-via82xx

Then restart.

Good luck,
Martin

What happens when you enter 'alsamixer' (without the quotes) in a console?

Can you help with this problem?
