When playing music I usually change my office MacBook’s sound output to a Sonos speaker, which is an AirPlay device. Sometimes the connection freezes and I have to reset output my default device and back to the office speaker. I wanted to automate both of these processes, so I found an AppleScript as a starting point. I modified it and created an Alfred Workflow with a keyword trigger. Here’s my version of the AppleScript. Feel free to modify it for your own use.
-- This script can be used to set/reset the sound output
-- Two devices because sometimes the AirPlay device loses connection
set myDevices to {"LG UltraFine Display Audio", "Office"}
tell application "System Settings"
-- sometimes it is already open to Sound, which causes an error
quit
delay 0.3
activate
delay 0.3
tell application "System Events"
tell process "System Settings"
set theWindow to first window
delay 0.3
end tell
keystroke "Sound"
delay 1
tell application process "System Settings"
tell radio button 1 of tab group 1 of group 2 of scroll area 1 of group 1 of group 2 of splitter group 1 of group 1 of window "Sound"
click
end tell
delay 0.5
set theRows to (every row of table 1 of scroll area 1 of group 2 of scroll area 1 of group 1 of group 2 of splitter group 1 of group 1 of window "Sound")
repeat with myDevice in myDevices
set device to myDevice as string
repeat with aRow in theRows
try
if name of first item of static text of group 1 of UI element 1 of aRow is equal to device then
set selected of aRow to true
exit repeat
end if
on error
display dialog "Error setting output sound to " & device
end try
end repeat
end repeat
end tell
end tell
quit
end tell
