To keep things simple I have recetly built my own HTPC and am using a HDA Digital Mystique 7.1 Gold soundcard for audio. When I use the windows remote to adjust the volume it only changes the volume of the master volume level and leaves the wave volume level unchanged. I know that my best bet is to simply change the volume on my AV Receiver and leave the Wave and Master volume at mid - max but when my girlfriend uses the HTPC she always uses the remotes volume control. Having said that I would simply like the option of being able to change the volume of my HTPC via the MS remote instad of just the amp. If more information is needed or if you would like a better explanation of what I am trying to acheive then please feel free to ask. Regards, Matt.
