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!
