[wdmaudiodev] Re: USB audio record problem

Hi, Jeff.

I gave that a try, just in case, but it didn't make a difference.  I'm still getting 000000's and FFFFFF's, with junk in the LSB.

It was worth a try, though -- thanks for the suggestion.  I do remember one of our customers having problems when they set dwChannelMask to FFFFFFFF.

Thanks,
-Dan

Hi Daniel,

I did read somewhere (don't ask me to find it, though) that dwChannelMask should be set to zero for audio capture, although looking at my own code for capturing 24-bit audio in 32-bit containers I've set it to SPEAKER_FRONT_LEFT | SPEAKER_FRONT_RIGHT and it's worked fine. All my stuff has been with PCI or PCIe devices, though, not USB.
