Detect if the audio output is changed

[nacerbaaziz]

Hello my friends
I have an urgent problem and we hope you can help me
I want to detect if the audio output of the device has changed
Such as the headset is connected or disConnected.
or change the default audio output
Is this possible?
I really searched a lot and found suggestions but unfortunately I did not understand them
Please explain to me
Greetings

Um, I see that you haven't given enough detail in what approaches you have already taken and researched. This may be difficult for a blind person.

How about some code for what you already have done in this 'urgent' problem?

Is this related to the other post you made at https://www.autoitscript.com/forum/topic/189645-an-important-question-in-the-bassdll-file/ ?

Would the condensed summary of AutoIt at https://github.com/J2TeaM/awesome-AutoIt be of assistance?

You need to implement something like this:

Sorry dear
i not understand very well
please I want more clarification

[KaFu]

Start the script in SciTE, switch your audio device manually and see the console notification.

[nacerbaaziz]

Dear brother
to be  everything is clear for me
please provide this service to me
I want when I change the default audio output the script execute these commands
####
    _BASS_Free()
_BASS_Startup(@scriptDir & "\dll\bass.dll")
If @error = -1 Then
    MsgBox (0, "", "DLL Does not exist?  Please check file exists.")

If @error Then
    MsgBox(0, "Error", "Could not initialize audio")
    Exit

What do you mean by this? what's not working, and what, if any, errors are you seeing?

[nacerbaaziz]

There's a error message that some of the variables in the program is Not Declarated

وهذه المتغيرات ليس لها علاقة بهذا الرمز.
حيث
انها مسؤوله عن أمور أخرى في البرنامج
please help me

[BrewManNH]

Declare them then. I'm not getting that from what you posted by the way, so it is somewhere else that you're getting that error. Probably in you main script or one of the other includes you might have in it.

There's no way to troubleshoot this without know what variables aren't declared or where they're used in the script.

[nacerbaaziz]

But the problem is if I don't include this file, everything's fine.
