Dear Steve,
My Hercules Game Theater XP is also working perfectly (meaning that I hear sound loud and clear) when MAD is set at 24 bits (the card's chipset features a 20 bit D/A converter). The issue is what the soundcard is actually outputting: 16 bit, 20 (my card)or 24 bit (your card)?
I mean that MAD surely outputs 24 bits, but are these actually getting through the OS/drivers/hardware to the D/A?
My humble opinion is that without *external* measurement (bitscope, oscilloscope, 2nd PC with 24/96 card really working at 24 bits to record your output) one cannot tell.
