I want to know why my laptop can't record 16khz sampling audio.
The sampling rates I can have using my laptop are higher than 16khz. e.g, 44khz, 48khz, 192khz, and so on...
I need to record 16khz sampling audio using my laptop.
Sound card in my laptop is Conexant 20671 SmartAudio HD

Although I can record 16khz sampling by Sound Forge 8.0, I am doubt whether the recorded audio is really 16khz sampling or not. Because the sound card can't record 16khz sampling, I think there may be some problems on the recording process.

Could you give me any hint why the sound card can't record 16khz?
and any method to identify whether the recorded audio by Sound Forge 8.0 is really 16khz?

Thanks.

First of all I'm not completely sure this is impedance mismatch, but from what I found on the Internet I believe it is. It seems to be a common problem.
