Microsoft Wireless Entertainment Desktop 7000 - volume control iss

Hello,
I installed a new soundcard ( M-audio Delta Audiophile 2496 ), and
downloaded the newest drivers for this.
After a successful install, keyboard volumecontrol buttons wont work!
(mute button is dead as well).

It seems like this keyboard I'm using (Microsoft Wireless
Entertainment Desktop 7000,
http://www.microsoft.com/hardware/mo...s.aspx?pid=081)

is only tuned to adjust overall system volume, but this control is
somewhat hijacked by the M-Audio driver/software!! Only Wav volume
remains in the system-tray. I have a friend with the same problem,
except he has another type of keyboard. However the principle of the
case is the same.

I do some teaching in pro-tools, and very much need these
keyboard-functions for my sessions.
There must be some sort of workaround for this ?
