I found a couple scripts that should help you out. I have not tested these scrips so don't hold me to them.

SOUNDCARD ANALYSIS AHK (Run First)
; SOUNDCARD ANALYSIS
; Use the following script to discover your soundcard's capabilities (component types and control types).
; It displays the results in a simple ListView.
SetBatchLines -1
SplashTextOn,,, Gathering Soundcard Info...
; Most of the pure numbers below probably don't exist in any mixer, but they're queried for completeness.
; The numbers correspond to the following items (in order): CUSTOM, BOOLEANMETER, SIGNEDMETER, PEAKMETER,
; UNSIGNEDMETER, BOOLEAN, BUTTON, DECIBELS, SIGNED, UNSIGNED, PERCENT, SLIDER, FADER, SINGLESELECT, MUX,
; MULTIPLESELECT, MIXER, MICROTIME, MILLITIME
ControlTypes = VOLUME,ONOFF,MUTE,MONO,LOUDNESS,STEREOENH,BASSBOOST,PAN,QSOUNDPAN,BASS,TREBLE,EQUALIZER,0x00000000, 0x10010000,0x10020000,0x10020001,0x10030000,0x20010000,0x21010000,0x30040000,0x30020000,0x30030000,0x30050000,0x40020000,0x50030000,0x70010000,0x70010001,0x71010000,0x71010001,0x60030000,0x61030000
ComponentTypes = MASTER,HEADPHONES,DIGITAL,LINE,MICROPHONE,SYNTH,CD,TELEPHONE,PCSPEAKER,WAVE,AUX,ANALOG,N/A
; Create a ListView and prepare for the main loop:
Gui, Add, Listview, w400 h400 vMyListView, Component Type|Control Type|Setting|Mixer
LV_ModifyCol(4, "Integer")
SetFormat, Float, 0.2 ; Limit number of decimal places in percentages to two.
Loop ; For each mixer number that exists in the system, query its capabilities.
{
CurrMixer := A_Index
SoundGet, Setting,,, %CurrMixer%
if ErrorLevel = Can't Open Specified Mixer ; Any error other than this indicates that the mixer exists.
break
; For each component type that exists in this mixer, query its instances and control types:
Loop, parse, ComponentTypes, `,
{
CurrComponent := A_LoopField
; First check if this component type even exists in the mixer:
SoundGet, Setting, %CurrComponent%,, %CurrMixer%
if ErrorLevel = Mixer Doesn't Support This Component Type
continue ; Start a new iteration to move on to the next component type.
Loop ; For each instance of this component type, query its control types.
{
CurrInstance := A_Index
; First check if this instance of this instance even exists in the mixer:
SoundGet, Setting, %CurrComponent%:%CurrInstance%,, %CurrMixer%
; Checking for both of the following errors allows this script to run on older versions:
if ErrorLevel in Mixer Doesn't Have That Many of That Component Type,Invalid Control Type or Component Type
break ; No more instances of this component type.
; Get the current setting of each control type that exists in this instance of this component:
Loop, parse, ControlTypes, `,
{
CurrControl := A_LoopField
SoundGet, Setting, %CurrComponent%:%CurrInstance%, %CurrControl%, %CurrMixer%
; Checking for both of the following errors allows this script to run on older versions:
if ErrorLevel in Component Doesn't Support This Control Type,Invalid Control Type or Component Type
continue
if ErrorLevel ; Some other error, which is unexpected so show it in the results.
Setting := ErrorLevel
ComponentString := CurrComponent . ":" . CurrInstance
if CurrInstance > 1
ComponentString = %ComponentString%:%CurrInstance%
LV_Add("", ComponentString, CurrControl, Setting, CurrMixer)
} ; For each control type.
} ; For each component instance.

TOGGLE MIC AHK (Modify then run second)
; ToggleMic.ahk
;
; Author: Peter Provost
; Git Repo: http://github.com/PProvost/AutoHotKey
;
; Description: Toggles the microphone on and off when mouse
; button 4 is pressed
#NoEnv
#SingleInstance force
; MouseButton4 (XButton2 in AHK) will toggle the microphone mute
; state. Note: the mixer value (4) may need to change for your
; system. Use the SoundCardAnalysis script from the AHK docs
; for the SoundSet function to find your mixer value.
*XButton2::
SoundSet, +1, Microphone, Mute, 4
SoundGet, mute, Microphone, MUTE, 4
SoundPlay, %soundfile%
; TrayTip, ToggleMic, %soundfile%, 3
TrayTip, ToggleMic, Microphone mute is %mute%, 3
return
Just make sure to run the soundcard analysis first to see what number your microphone is so you can put it in the Toggle Mic ahk. Also just change XButton2(Mousebutton 4) to the button you want to use. Like LControl or XButton1(Mousebutton 5)
