Hi, I got the same problem here on a few Hp units. I also read somewhere else people having the same problems with some Toshiba laptops.
- I've installed Vista Ultimate x64 (SP1) on 2 current Hp units and a Compaq (same computer different case).
- Plugging into the headphone jack with a cd playing (or any audio, using any audio software) the sound still plays out the laptop speakers but not through the headphones.
- Going into the "sound" control panel, it registers when you plug or unplug your headphones.
- With the headphones plugged in, you can actually test them by using the preview sound... THIS WORKS. I get a tone in the headphones! (with or without a Cd playing at the same time)
So the fact that the same problem occurs on 3 different laptops using the same operating system and that the headphone jack DOES work using sound preview, means it's gota be some kinda driver
issue.... right?? (or a Hp/Vista compatibility issue)
I read somewhere about forcing an XP sound driver
to work on Vista but that didn't work for me.
Anyone?? Seems a lot of people having the same problem.
Maybe I'll go backwards and try Home Basic...
