Hi all. I am using Windows 2000 SP3. When I play the game the video is fine so I know there is no problem with that. And I can even setup the sound in the setup program for it. But then when I go to test it, it says Initializing and then like 2 seconds later it says "Playback Failed, Possibly Due To An Invalid Or Conflicting IRQ" and the sound still doesn't work. I don't really know what kind of sound card I have all I know is that it is onboard because I have a HP Pavilion motherboard. Not really much else to tell you. I open the command prompt in Start > Programs > Accessories and then I load DOSDRV in it and it says loaded successfully and then I load the setup program for Shadow. There is only one menu called Sound Setup and it I can Choose Sound FX card and test it and all that. The version I have doesnt let me set up a Music card because all the music comes off the CD and i guess uses the same settings. But I have it set on Sound Blaster or compatible, 220, 5, 1, 5 and it the emulation must be working because it lets me choose voices and channels and Hz and all that and it used to say Sound Blaster could not be found on the IRQ or some message similar to that so I know the emulation is working. I don't know what the problem is so if someone can help I'd really appreciate it thanx!!
