Works fine with MW4: Black Knight & update patch 1.
Have tested with Win98se, Win2k, WinXP.

Tested on Celeron 466MHz, 256MB SDRAM, ABIT BP-6 & Soyo 6VBA 133 motherboards, SoundBlaster Live 512 Full & SoundBlaster Live Value, Voodoo3 2000 PCI 16MB, & Asus V6800 AGP 32MB (GeForce DDR) (tested with all hardware on both motherboards with both vid & soundcards)

Tested on AMD Athlon Tbird 1.4GHz, 256MB PC2100 DDR RAM, Gigabyte 7DXR, Asus V6800 AGP 32MB (GeForce DDR) & Gainward Ultra650 XP AGP 128MB (GF4 Ti 4200), Onboard SoundBlaster PCI 128 chip & SoundBlaster Live 512 Full.

SBPCI 128 PROBLEM:
Soundblaster PCI 128 required that I use DirectSound for Sound Output Device with "Creative SBPCI Direct Sound Driver" Selected.
SB Live Full & Value both allowed WaveIn and WaveOut without interfering with Mech4's Sound.
