Can't get audio to work on old CF-51

[r0bc]

A friend wanted me to upgrade a older Panasonic CF-51 to W7 From XP and I did but for the life me I can't get the sound to work. The device is installed and you can see that there is sound but it's not coming through the speakers. If I can't get the sound to work and I got a USB sound card would it enable the sound in the speakers? Panasonics don't even have Vista drivers I can find and sound did work in XP

My Google-Fu reveals no vista/W7 drivers for that unit also.

Make that "official" drivers. You may find some custom ones, but I don't visit websites unknown to me any more. YMMV

Yeah I can't get sound...its weird. I've tried a lot of different drivers ...I half think its I'm missing a driver for the function keys or something cause the sound device is installed.
If I got a USB sound card would it enable the sound in the speakers do anyone no? Everything else works perfectly.
