Python Script that switches through audio output on Mac, can add uid to an ignore list, pops up a notification with output name. USE: I bind the script to a shortcut and add a keyboard shortcut to switch between audio outputs. (Uses https://github.com/deweller/switchaudio-osx)

AudioSwitcher.py

#!/usr/bin/env python3

import os
import subprocess as sp
import json
 
def notify(title, text):
    os.system("""
              osascript -e 'display notification "{}" with title "{}"'
              """.format(text, title))
              
## PATH TO SwitchAudioSource
switch = "/opt/homebrew/opt/switchaudio-osx/SwitchAudioSource"

## IGNORE LIST
ignore_list =["BuiltInSpeakerDevice"]

## LOAD DEVICES INTO LIST
devices =[]
device_json = sp.getoutput(switch+' -a -f json')
device_json_list = device_json.split("\n")

for i in device_json_list:
  json_output = json.loads(i)
  if str(json_output["uid"]) not in ignore_list:
    devices.append(json_output["uid"])

##Current
current_device_raw = sp.getoutput(switch+' -c -f json')
current_device_json = json.loads(current_device_raw)
current_uid = current_device_json["uid"]

## CHECK TO SEE IF THE UID IS IN THE ALLOWED LIST
if current_uid in devices:
  device_index = devices.index(current_uid) 
  if device_index == len(devices)-1:
    device_index = 0
  else:
    device_index +=1
elif current_uid not in devices:
  device_index = 0

## SETS THE OUTPUT
output = sp.getoutput(switch+' -u "'+devices[device_index]+'"')

# POPS UP THE NOTIFATION
output_text = sp.getoutput(switch+' -c')
notify("Audio Output", output_text)
