Using Built-In Volume Keys With External Soundcard

[adam777]

Hello all.
I've recently received my Audigy2 ZS notebook Soundcard and i was wondering if there's a way i can make the built-in Thinkpad volume keys to work with the card.
At first i thought the volume keys were relevant only for the internal soundcard/speakers but to my surprise the "Mute" key does work with the external soundcard, also, the volume up/down keys can cause the volume to "un-mute".
So, i thought there might be a way to cause the other 2 keys (volume up/down) to work as well.
Thanks in advance, Adam.
