Same audio through laptop speakers and external speakers

Hi,

I'm using a Packard Bell laptop, Windows Vista and a Realtek sound card.

I've searched a lot to find how to NOT mute my laptop speakers when I insert something in the audio-out-jack.

The next threads say it's not possible by the hardware:

techspot.com/vb/topic130170.html
They're closed, so I can't comment on them.

BUT when I dual boot to Ubuntu (using the same hardware), I can easily choose to mute the internal speakers, or the jack, or none at all. So why can't it be possible on Vista?
 
You answered your own question... It's a software/OS issue. If Vista's Realtek options in the Control Panel don't give you the same options as in Ubuntu, you're out of luck
 
Oh ok. I can live with that.
Just some people (in the threads above) said "its impossible technically." and that it's a hardware thing.

Thanks!
