I have an MAudio delta 1010 (10 ins / outs, 24-bit/96kHz capable).  I want to query its capabilities in c++, but the windows WAVEOUTCAPS.dwFormats definitions appear to be limited to 16-bit/44.1kHz:

WAVE_FORMAT_1M08 11.025 kHz, mono, 8-bit
WAVE_FORMAT_1M16 11.025 kHz, mono, 16-bit
WAVE_FORMAT_1S08 11.025 kHz, stereo, 8-bit
WAVE_FORMAT_1S16 11.025 kHz, stereo, 16-bit
WAVE_FORMAT_2M08 22.05 kHz, mono, 8-bit
WAVE_FORMAT_2M16 22.05 kHz, mono, 16-bit
WAVE_FORMAT_2S08 22.05 kHz, stereo, 8-bit
WAVE_FORMAT_2S16 22.05 kHz, stereo, 16-bit
WAVE_FORMAT_4M08 44.1 kHz, mono, 8-bit
WAVE_FORMAT_4M16 44.1 kHz, mono, 16-bit
WAVE_FORMAT_4S08 44.1 kHz, stereo, 8-bit
WAVE_FORMAT_4S16 44.1 kHz, stereo, 16-bit

1) Is there a way to parse out DWORD dwFormats to get the actual capabilities of my card?
2) Will windows fill the member with WAVE_INVALIDFORMAT? (I havent actually tried querying the Delta yet)
3) What can I do? Oh My!

:)

AND: Why don't you use the wChannels member of this structure?

I'm using vc++ 6 from Microsoft Visual Studio 6, must not have the latest mmsystem.h file.  I wonder if I'll have to upgrade, mebbe the older stuff just can't deal with it.

In any case, u get the points because u defined them for me :)

Is there a way to use the wChannels member to determine the sampling rate and resolution?

thanx:)

The wChannels member is only to get that you have a 10-channel device you otherwise wouldn't get using dwFormats.
