I've tried changing settings for a while to see what happens, but it never completely solves the problem.
So when I stopped using Dropbox and started syncing manually, the problem disappeared completely.
So I don't think it's Alfred's bug.
Here's the script I use on my Ventura.
please refer.
if (system attribute "sys1") is not 13 then return
open location "x-apple.systempreferences:com.apple.Sound-Settings.extension"
delay 2
tell application "System Settings"
tell application "System Events" to tell application process "System Settings"
tell window "Sound" to tell group 1's splitter group 1's group 2's group 1's scroll area 1's group 2
click tab group 1's radio button 1 --Output tab
tell scroll area 1's table 1
set RowsList to every row
set devList to {}
repeat with i in RowsList
set devName to i's UI element 1's group 1's static text's name
if i's selected then set defaultName to devName
set end of devList to devName
end repeat
end tell
end tell
end tell
end tell
tell application "Finder"
activate
set devSel to (choose from list devList default items defaultName with prompt "Select Device...") as string
end tell
tell application "System Settings"
tell application "System Events" to tell application process "System Settings"
tell window "Sound" to tell group 1's splitter group 1's group 2's group 1's scroll area 1's group 2
click tab group 1's radio button 1 --Output tab
tell scroll area 1's table 1
set RowsList to every row
set devList to {}
repeat with i in RowsList
set devName to i's UI element 1's group 1's static text's name
if devName contains devSel then
set i's selected to true
delay 1
exit repeat
end if
end repeat
end tell
end tell
end tell
quit
end tell
