Hi all,

I have a Toshiba C665-P5010 laptop, and I'm running Ubuntu 10.04 LTS. When I connect the headphones, the internal speakers were not getting muted, and I was getting output from both the speakers and the headphones. I tried the steps outlined here:

But the issue remained.

I tried the steps here:

(section "Mute speakers when headphones are used")

Now, it appears my soundcard is completely disabled (When I click on the speaker icon and go to "Sound Preferences", there is no device in the "Hardware" tab, and on the "Output" tab, there is only one entry "Dummy Output").

How can I reverse this process, and get my original issue solved?

Thanks,
