Hi, Danyfirex. For XP I know you could tell from the registry; looking at HKEY_LOCAL_MACHINESYSTEMCurrentControlSetHardware ProfilesCurrentSystemCurrentControlSetEnumHDAUDIO would show a switch between 0x00000001 for headphones and 0x00000004 for speakers. However, I think that method has been abandoned in Win7.

There is also the DirectSound API, which has a Device.SpeakerConfig.Headphone property, if you want to go that way. You'd have to poll the devices and look for a match. I haven't played with this myself, but you might search MSDN for more info. Below is just the first hit I came upon.

Looks like you can do this with the BASSWASAPI add-on BASS_WASAPI_SetNotify function

BASSWASAPI beta

Thank you rover I'll see that.

I could have used this a few years ago, and TTBOMK there's nothing like this on the forum,

so my curiosity was piqued to check out the device change notification function in the BASS_WASAPI dll.

It works, but is not *useable run from a script.

Perhaps someone will be inspired to code a DLL in another language to implement this.

Should run on Vista, but only tested on Win7 x64 as a 32bit process (does not run as a 64bit process)

The 64 bit version of the latest dll still won't load, as mentioned by BrettF (DllOpen returns -1)

*The notification callback is run in a new thread and AutoIt is not threadsafe.

The basswasapi.dll needs to be run from an app compiled in another language

with some inter-process communication back to AutoIt scripts.

Detects I/O connect/disconnect, but crashes when inputs connected, a bit more stable when outputs connected/disconnected

+ ! _BASS_WASAPI_Startup   = True @error: 0 @extended code: 0
+ ! _BASS_WASAPI_SetNotify = True @error: -1 @extended code: 0

thank you for your time. that's great. I wanna test it.
