Hi,
unfortunately there are several cases which have this issue.
You may file a bug and in case describe the solution to it, thanks.

Options which may help:
sudo gedit /etc/modprobe.d/alsa-base

at the end of the file add:
options snd-hda-intel model=vaio

Disable the surround option

Please talk me through "slowly" which applications I am to use to make the change you describe.

Thank you,

Stu

Sam is saying, go up to the top taskbar and click on

Applications - Accessories - Terminal

and into the terminal/command window/console enter

cd /etc/modprobe.d
ls
sudo cp alsa-base alsa-base-030509
ls
sudo gedit alsa-base

note that copy&paste might be useful with this but CtrlV doesn't work in the terminal console so you'll have to use mouse paste instead ;) The first "sudo" command will need your normal user password, not your SuperUser/Root one. When you type it in it wont give away with stars just how long (or short) your password is but it does quietly accept your key strokes. The 2nd sudo probably wont need your password because the first gives you 15mins free to use sudo. The "ls" is a lower-case "LS" and shows a LiSt of what's in the folder. The CoPy command makes a backup of the file we are about to edit in case things go wrong. The 2nd "ls" shows you that the copy copmmand has worked ;) Gedit is a great little text-editor, there's a lot to choose from but Gedit is good. In the "alsa-base" file add to the end of the file

options snd-hda-intel model=vaio

and hunt for the surround option and either set it equal to "disable" or else put a # mark at the beginning of the line it's on. Sorry i haven't used alsa-base so i don't know which of those 2 options is more appropriate. Sam suggests reading through

to make this last part easier. Then just click on "Save" in gedit and let us kno how it goes!

Hope this helps!
Good luck and regards from
