Hello.

I have been trying to get the AUHAL Audio Input example (technote: TN2091) to work.
I have successful at receiving all silence in the AUHAL's input callback.

I have been searching the list archives for quite some time now and have noticed that a lot people have had the same problem. I have yet to find a solution.

I am using a USB microphone with mono input.

It is using the following ABSDs for the conversion (to/from) :
- - - - - - - - - - - - - - - - - - - -
Sample Rate:8000.000000
Format ID:lpcm
Format Flags:B
Bytes per Packet:4
Frames per Packet:1
Bytes per Frame:4
Channels per Frame:1
Bits per Channel:32
- - - - - - - - - - - - - - - - - - - -
- - - - - - - - - - - - - - - - - - - -
Sample Rate:8000.000000
Format ID:lpcm
Format Flags:6
Bytes per Packet:4
Frames per Packet:1
Bytes per Frame:4
Channels per Frame:1
Bits per Channel:16
- - - - - - - - - - - - - - - - - - - -

Any help or suggestions is greatly appreciated.
