Hi,Please try below commands to mute/unmute the mics. i tested it and it works well. you can read the button signal and then use below command to mute the mics. for more info, please refer to https://wiki.archlinux.org/index.php/PulseAudio . thanks.  
To mute/unmute the microphone:
$ pactl set-source-mute 1 toggle

Hi,
1. can I directly solder speaker to HP_L and HP_R of board to board
connector to Speaker like 1 to 5 W power. 

I  use the 450050 speaker, the sound is quite low, but you can hear the voice. 

2. Can I make setup that play both external speaker from HP_L and HP_R of
board to board connector and Headphone from 3.5mm jack and at a time only
one will work.  


Yes, you can hear both of them, but the Speaker connect HP_L and HP_R of board is quite low sound. thanks. 

Merry Christmas  and Happy New Year.best rgdsBill
