I've noticed under Vista that our card is always set to16-bit 44.1kHz
sampling, even though it supports 24-bit resolution and all the commonly
used sampling rates up to 96kHz. I've discovered there is a "Format" tab in
Device Properties (accessed from the Control Panel) that allows this to be
changed, however the user is cautioned against doing so. "Unless you have
good reason to do otherwise, it is strongly suggested that you use the
values that the system has chosen for you."
Is there any way for the driver to tell Windows what its preferred bit depth
and sampling rate is, so as to make this the default format for the device?
Our hardware runs its converters at a fixed rate (96kHz with 24-bit
resolution), with other rates and bit depths supported in firmware, and if a
software sampling rate converter is going to be inserted into the playback
or recording stream it would be preferred that it convert directly to the
card's native format.
