Sadness.
I do not believe there are any ME drivers for the SoundBlaster PCI line. The PCI line is different from the SB Live line.
I'm not sure but I couldn't find a model called "SoundBlaster PCI 16". I found a SoundBlaster 16 (no ME drivers) and several SoundBlaster PCI[128,256,512] cards (no ME drivers).
Are you using an old Soundblaster 16? If so I would suggest a definate hardware upgrade.
