Detect headphones in Windows [duplicate]

Asked 3/4, 2011 at 1:33 Answered 3/4, 2011 at 3:57

I'm trying to detect if the headphones are plugged in on Windows. I've already tried DirectSound and the NAudio library and have not had any success. Does anyone have any suggestions?

NOTE: this question is a duplicate of this question, but the answer to that question didn't contain any code samples or tutorials.

Duplicate of this question: #862101 That question isn't tagged for Windows, but Larry Osterman is a Microsoft software engineer who's worked on the audio subsystem for years so he knows what he's talking about. He doesn't reference any samples or tutorials of how to do this, so I'm still interested to see if anybody digs anything up in response to this question. – Raouf 3/4, 2011 at 2:7

please pardon my edit of your question, but I wanted to make sure it isn't closed as a duplicate. – Raouf 3/4, 2011 at 2:9

Are you trying to detect analog headphones plugged into the line-out jack of a soundcard or USB headphones? That will heavily influence my answer. – Needlefish 3/4, 2011 at 5:23

@selbie: only analog.. But I think I find the answer.. – Adorl 3/4, 2011 at 12:24

So...I think I might found something REALY obscure..

Can any of you guys check if that works? - You MUST have the NAudio library referenced..

var enumerator = new MMDeviceEnumerator();
var d = enumerator.GetDefaultAudioEndpoint(DataFlow.Render, Role.Multimedia);
Console.WriteLine(d.Properties[new Guid("46d16a2c-5654-41c0-911e-7860d2bce7ee")].Value.ToString());

This property return's 1 (Plugged) or 0 (Unplugged).. and It's working realy good for me..

UPDATE: Just published the app on CodePlex - iTunesHead

I have tried running this project on my PC and that particular GUID does not seem to exist (Null reference), so I think it depends on hardware/drivers. I also tried comparing all the device properties before/after plugging and unplugging headphones and nothing changes. – Coker 28/5, 2012 at 19:17

Yeah..that was what I was thinking when I found this GUID, must be a thing only on my Dell, so I kinda drop this project after that.. – Adorl 2/6, 2012 at 1:23

-1

What about Microsoft.DirectX.DirectSound.Speakers?

A Speakers object should have one of the following speaker type properties set to true:

FivePointOne

Headphone

Mono

Quad

SevenPointOne

Stereo

Surround

All the prop's retun the same value. I keep plugging/unplugging the headphones, all stay the same.. HeadPhone: False FivePointOne: False Mono: False Quad: False SevenPointOne: False Stereo: True Surround: False – Adorl 3/4, 2011 at 2:13
