Cant u just turn off the speakers? Anyways try to configure the sound from the KDE control center. (Under System Menu). If it becomes desperate u can always disable the speaker hardware from the drakconf.

Hi rooot,
Thanks for your reply. Nice solution. But i dont know how to i disable the speaker hardware. I will be very thankful for you if you provide me the steps to disable the inbuilt speaker in my laptop.

I would check your settings in Kmix and check that "External Amplifier" is set to on and that headphone auto-sensing is on too. Other than that I have had problems with Mandriva using the wrong driver for the soundcard in my Inspiron. do you find it doesn't always load on boot?

Hi bigtomrodney,
I checked all those stuffs in kmix. There is no separate option for headphone and inbuilt speaker.The options that i have in my Kmix are
1) Master
2) PCM
3) Capture Mix
Even i tried installing the latest driver from ALSA. But the problem appeared again.
The better solution fot this will be disabling the inbuilt speaker.
i dont know how to disable the inbuilt speaker. Is there any option available ?

There may be an option in your BIOS settings to disable the speaker. You would need to explore, but be cautious about what you alter.I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso

Alsa 1.0.13
I had a similar problem for the longest time, now being able to get headphones to work. I found looking around online that there was a change in alsa1.0.13 which allowed the volume for the headphones to be set along with the main speakers. Although not automatic, perhaps if you upgrade to alsa1.0.13 you will be able to turn the speaker volume to 0, then turn the headphone volume up. This has worked for me.
