[I hope this doesn't fall into the "Well DUH, we all knew that" category.]

Visited Rob's MAD web page to see if there was anything new and noticed this: "24-bit output is not reported to work with the DirectSound plug-in." Well, let me make a report that it does indeed work with Direct Sound.

I had done a fresh install of W2k and SP3 a couple of weeks ago on my multimedia PC. Loaded the latest VIA 4-in-1 driver support. The only sound device is M-Audio 24/96. Fresh install of Winamp 2.81. Went into Winamp preferences and set up MAD @ 24 bits. Output apparently defaulted to DS (I didn't check it at the time.), but everything worked perfectly. I became curious what Winamp was using when I saw the above comment about DS, so I looked and sure enough DS was enabled and operational. To double check, I removed "out_wave.dll" and it still functioned normally. I've also confirmed that MAD is operational by the "active" checkbox and by playing with the title options.

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.
