Hi Guruprasad!

I need to know a little bit more about your system:

If you click the speaker icon (top right corner of screen), select "Sound Settings..." then "Output", what values of "Connector" are there?
Is the "Connector" changing automatically when you plug/unplug headphones, and if so, between what values?
If you change "connector" manually, will that bring sound back to the speakers?

[Guruprasad (lgp171188)]

Connector shows 'Analog Speaker' and 'Analog headphones' on unplugging and plugging the headphones, but when I checked in alsamixer, the volume of the speaker is set to 0 and manually raising to 100% causes the speaker audio to work normally.

[Guruprasad (lgp171188)]

But the Sound properties GUI shows 100% volume even when the volume of the speaker gets set to 0 on unplugging the headphone.

Here is the screencast showing the problem

Oops, looks like Youtube had issues with my .ogv file. Here is the correct link. http://www.youtube.com/watch?v=w2BU2E7ldPA. Even though the speaker volume was 100% before connecting the headphones, it gets set to 0 after disconnecting the headphones when it gets unmuted.

Hi, I believe I've found the bug now. Once a fix is released to the proposed repository, I hope you will be able to verify that it works.
