I recently needed to re-install Windows 7 (x64 pro), and everything is working great now except for one feature relating to sound.
I have a USB dock which has speakers plugged into it, which I use most of the time, however sometimes I want to plug in headphones.
It used to be that when I wold plug the headphones into the laptop port, it would mute the dock speakers, and when they were pulled, the dock speakers would resume (with independent volume controls).
Since the re-install, however, the computer only mutes the laptop speakers (which are not running anyway) when the phones are plugged in, and of course since the dock is generating the music, there's no sound in the headphones.
I just cannot figure out how to let Windows see the headphone socket on the laptop as a device which should take precedence over the dock speakers.
It feels as if the computer should treat the headphone socket completely independently from the internal speakers.
Any help/ideas would be very much appreciated.
