no sound on UBUNTU 9.10 (laptop-ACER Extensa 4620).

when i open System>Preferences>Sound it shows
"Waiting for sound system to respond" and nothing happens after that.
Volume Control icon has also disappeared from the panel.

Do i need to install any driver?
Also how do i check my sound driver?
plz help.

See this to hopefully enable sound on your laptop:

I'm not sure how old that article is, but the correct package for the backported modules that you need to install for Ubuntu Karmic 9.10 is:

Code:

linux-backports-modules-karmic-generic

Then edit /etc/modprobe.d/alsa-base as it says in the article.
First, backup /etc/modprobe.d/alsa-base for safety before you edit it:

Code:

sudo cp /etc/modprobe.d/alsa-base /etc/modprobe.d/alsa-base.bak

Then add this line to the end of /etc/modprobe.d/alsa-base:

Code:

options snd-hda-intel model=acer

You may need to reboot to get the sound going. After you reboot open alsamixer in the terminal and move all the volume levels all the way up using the arrows keys. Hit the Esc key twice to exit alsamixer.
Hope this helps.
