Mic Problem in ubuntu 10.04 for Root user

image0

I am using ubuntu 10.04 in my laptop. I created a user when installing ubuntu . The sound and Mic are working fine for that user. I enabled the root by using the following command

To enable root user. Login with existing user then goto Terminal.

sudo passwd root

Now the root user is enabled. I logged in with root user. I seen the sound is not working for me. The volume icon is always in "mute" state

What is the Error shown ...?
When i click the "Sound Preference" in volume button or System --> Preference --> Sound it always shows a Warning message "Waiting for Sound system to respond"

Now you need add a new startup application. Add "pulseaudio" as a startup application

Then logout and login again. For min i restarted my system. Now you can see the Volume control icon in unmute state and you can edit your sound preference now.
