Good Morning All.

I am a new ubuntu user. So please forgive me if this question is too basic.

I have installed Ubuntu 11.10 in my machine. I have logged in as USER_A. My external audio device is a Headset and I was able to hear the audio properly.

I need to join my Ubuntu machine to a window's domain (my office server). I followed the steps explained in http://www.ghacks.net/2010/04/21/join-a-ubuntu-machine-to-a-windows-domain/ and was successful in joining my ubuntu machine to the windows domain.

sudo apt-get install likewise-open5
sudo domainjoin-cli join DOMAIN USER_B

Now when I logged in as USER_B, there is no audio for this user in the same machine.

I crossed check with my User_A account. There is no issues with the sound for User_A. Only for User_B, there is no audio.

When I checked the sound settings of User_B, there is no device listed in Hardware, Input and Output. Whereas for User A, my Headset is listed in Input and Output.

Can anyone please help me on this. Why there is no sound for User_B?

Thank you.
