    Default Format where you select sound quality frequency is grayed out.
    On any Wave Out devices output format 16/48.
    But on a Master Mixer device output format 32/48.
    First, why the choice is blocked?
    With what real bit depth is the audio stream transmitted to the sound card?
    If I listen to music, choose Stereo Mix, is there 32/48, will the sound stream to the card be 32 bits?
    If I choose Wave Out 2/3 then 16/48?
    Or is the stream always converted to 24 bits?

    Hello.
    Sound processing by the card's DSP is always done at 48 kHz. The choice is blocked for this reason, I think. This setting is the best, because with it Windows resamples all audio streams to 48 kHz before transmitting to the card.
    For Wave Out 2/3 all audio is converted by Windows to 16-bit 48 kHz, and for Stereo Mix to 32-bit 48 kHz.
    Hope this helps.

    The card doesn't support any other sample rate for the output... either that or the driver's restricting it.

    Why then isn't 32 bits used for WaveOut 2/3?
