Sound from both laptop speakers and external speakers

[Markus]

Hi!
I have tried searching google for my problem, but I can't seem to find the solution to my problem, even though there obviously are other people having the same problem (mostly in different tastes of Ubuntu). None of the solutions I saw on other sites is working for my system. The weirdest thing about this problem is this: Yesterday I installed Linux Mint 5 (Elyssa), and did no configuration of the audio, except choosing the audio-mixer to use under wine, to get music playing from Spotify. This night I wanted to try to upgrade from Elyssa to Felicia, but it went wrong, and I installed Elyssa from a CD again. This time, the problem described in the text under and in the topic-title came along, even though I haven't configured any audio-options (yet).

My problem is that when I am playing music (or any other sound), the sound is coming from both the laptop speakers and the external speakers or headphones plugged into the mini-jack.

I'm currently running Linux Mint 5 (Elyssa) on a HP Compaq nx6325. HP's website is saying this about the audio for my laptop:
http://h18000.www1.hp.com/products/quic ... 7_div.HTML

PremierSound audio/speaker subsystem
ADI1981HD High Definition CODEC
Integrated 16-bit Sound Blaster Pro compatible audio
24-bit DAC
Integrated stereo speakers
Integrated microphone
External volume up, volume down, and mute buttons
Stereo headphone/line out
Stereo microphone in

I'm sorry if I explain in a hard and non-understandable way, and you have to tell me if I really do, because then I will try again. Thank you.

This must be an old laptop, or?
Because
Integrated 16-bit Sound Blaster Pro compatible audio
does not exactly sound new to me
Unfortunately I do not have any solution at hand
Run lspci in a terminal and post here (right click to copy)
There may be some clue there

I thought the turning off of the speakers is done inside the card when it senses something is plugged in, independant of the operating system and the rest of the computer

Unfortunately this is not the case.....

Thank you for trying to help, guys. But after a couple of restarts, the problem fixed itself, and I have no idea what made it fix itself. Might just have been a problem when initializing the sound-card?
