Hi All,

I am not developing an audio device driver, but rather I am interested in 
finding out the default sampling rate for a given device. I am developing an 
application that must operate on 8 kHz sampled data. I currently support 
resampling to/from 48k, 44.1k, 22.05k, and 16k endpoint sampling rates. 
However, during testing, I came across a device using a 32 kHz sampling rate, 
and I want to figure out if a user intentionally changed the sampling rate to 
32 kHz or if it was the default sampling rate at installation.

TL;DR: Is there an easy way to find the default sampling rate for a given 
input/output device in Windows?

Thanks,
Bill
