Re: How to mute microphone of a phone device while on the call. ??

Hi matthias,
So, will it be possible through hardware audio mixer api, to mute the
microphone only and continue functioning speaker-headset part of the device
??

And I want to ask another question.. With the help of lineGetID for
wave/out, wont I be able to set the volume to zero or mute the wave/out part
?? Just an idea, i have not tried it yet.. just wanted to ask..
