Hi all!

Mates, I am following the example PCM.C that I found at alsa web site. 
its a sine wave generator.
I am looking for a control that alsa provides to control the amplitude 
of the wave.

As I could found so for, there is just frequency control... I didn't 
find any amplitude control.

* I don't want to control the volume using alsamixer or even my sound... 
I want to generate a wave with predefined amplitude.

Does anyone could give me a little help??

Thanks a lot!
