### You feel me?
* An idea came up that what if I can hear my self typing, it might sounds a bit awkward but I kind like the clattering, it makes me excited, and the more up-speed the more I get, dreaming like a hack or some other shhxt hah


### Issue
* The first thing I am facing is that the Interal mic would shown `unplugin` while 3.5mm earphone pluged-in on my Surface7), no matter how many time I tried.

### Using hdajackretask
Aimming to turn off the mic on my earphone, so system will always detect buid-in(internal) microphon.

# First thing is to find out what pin is connected
# in my case I have 0x19 pin as my 3.5mm mic
$ sudo hdajacksensetest 
Pin 0x19 (Black Mic, Left side): present = Yes
Pin 0x21 (Black Headphone, Left side): present = Yes

# kill pulseaudio before running hdajackretask 
# so you wont encounter the error `Device or resource buy` 
$ pulseaudio -k    # might not be working if it's running as a daemon 
$ systemctl --user stop pulseaudio.socket

# overwrite  0x19 as 'Not connected'
# its up to you if you want to `install boot override`
$ sudo hdajackretask

# put back up pulseaudio
$ pulseaudio --start
#-------------------------------------------------------
# last monitor your mic by using the loop module
$ pactl load-module module-loopback latency_msec=1 rate=48000
# unload pulseaudio module
$ pactl unload-module moduel-loopback
