Is there any way to determine, programmatically when headphones are plugged into the computer?
Essentially, I just want to write a simple tool that will mute my sound unless headphones are plugged in. Is this even possible?
The audio ports detect that something has been plugged in by monitoring for a change in resistance across the port.
Open Control Panel and click on Sound. Under Playback, right-click and select Show Disabled devices. From the list of headphones, right-click on your headphone device name. Select Enable.
Your computer not recognizing your headphones is a fairly common issue in Windows 10 PCs. It could be caused by a corrupt or outdated driver, faulty USB ports (if your headset uses USB), an error in the connection (in case of Bluetooth, for example), or an issue with the headphones themselves.
In Windows Vista and beyond, you can use the device arrival and removal notifications and retrieve the endpoint formfactor to determine if the manufacturer of your audio solution considers a particular endpoint a "headphone".
Before Vista there was no way of determining this information.
