No Sound From Laptop's Internal Speakers

Asked by Krishna

There is no sound from Laptop's Internal Speakers in UBUNTU 9.04..
Perfectly ok when connecting External Speakers..
I don't have this problem while using Windows... Windows support both Internal And External Speakers...

I have Upgraded Alsa to 1.0.19 and then to 1.0.20 and still No Sound From Internal Speakers..
Everything else is perfect.. PCM, speakers or Front, Master all Full Volume..

The problem is not that I can get a faint sound from Headphones..
When I connect woofer or headphones, with my present sound settings, sound gets extraordinarily amplified and really perfect sound...
Problem only with Built-in Speakers..

I had posed this first as a bug.. i got a reply that I need 9.10 to solve this problem..
I really like to stay with 9.04 and 9.10 doesn't support certain things...

Is there a way to solve this without moving to 9.10.....
