Hi,

I am currently working on an audio sampling piece of software, and I am having some problems regarding a specific device. Since I suspect this is not the only device behaving in this fashion, I am seeking your advice.

Here's the problem;

The Griffin PowerWave reports the following physical formats for input;

0Hz, mono, 8 bits
0Hz, mono, 16 bits
0Hz, stereo, 16 bits

As you can see, there is no sample rate specified for these three formats.

The formats queried from the device is used to populate a menu. I want to be able to present the formats to the end user, but a format that specifies a 0Hz sample rate doesn't make sense.

How would you suggest I handle situation is handled?

Any suggestions are greatly appreciated!

Thanks,

Tommy Braas
