If the volume is that of the amplifier, changing the volume without the amplifier being enabled has no effect. This is the case of my laptop's HDA. Enable the amplifier by setting the EAPD bit, and the volume will work.

If you refer to wss from my mplayer's DJGPP builds, the HDA part is done by me. Be aware that some cards return wrong info about the plugged jacks, and besides you would have to use an interrupt routine for continuously checking the messages re: a jack plugged or unplugged. I didn't implement such a thing.
