Download Devcon.
Save it to C:\Windows\system32
Use Notepad to save the text below as riven.bat, editing the device name so that it matches what's listed in Device Manager, and the path to the EXE so that it matches what's in the existing shortcut:
devcon disable "unimodem half-duplex audio device" c:\games\gog\riven.exe devcon enable "unimodem half-duplex audio device"
What it'll do is automatically disable the device, launch the game, then enable it once you've finished playing, and that should save you the startup BSOD and the trouble of manually disabling and reenabling each time you play.[1]
