hands-free, gain control

Other Parts Discussed in Thread: TPS65950

Hi,

The environment: omap3evm, am37, gingerbread, kernel 2.6.37

Is it possible to control the gain of hands-free TPS65950 amplifier. How can it be done from alsa sound system. 

I enabled hands-free sound in ALSA and I can hear audio on R and L channel but I don't know how to control this?

Regards,

K
