Audio Not Working
 

i had recently installed ubuntu 7.04.

the problem is that there is no sound when i play any music file or video file. when i go to preferences->sound there are no devices listed unde the Device drop down menu.

Please help.I am desperate.

i have the following audio controller card:
VIA AC'97 Enhanced Audio Controller(WDM).

Sound is working perfectly in windows XP Pro SP2

please, post lspci and lsmod commands output

i have another problem cropped up.

after i enter my username and password i get this message:
"User's $HOME/.dmrc file is being ignored.This prevents the default session and language from being saved.Fiel should be owned by user and have 644 permissions.User's $HOME directory must be owned by user and not writable by other users."

the screen goes blank and after sometime i get this message:
"The GNOME session manager was unable to lock the file "/home/muskvar/.ICEauthority".Please report this as a GNOME bug.Sometimes this error may occur if the file's directory is unwritable.You could try logging in via the failsafe session and ensuring that it is."

WHAT DO I DO?

i have checked the permissions of the .dmrc file and they are 644 as specified.

output of : echo $HOME is /root.

i have installed ubuntu 7.04 on a standalone desktop system connected to the internet through a adsl modem.

PLEASE HELP!

I WOULD APPRECIATE IF SOME OF THE SENOIR MEMBERS HELP IN THIS.
