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/topic140707.html 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?
