Your PC’s headphone jack is hardwired to your sound card, which is automatically enabled when you start Windows for the first time. When multiple sound cards or playback devices are installed, Windows may adjust your preferences so that sounds no longer play through your headphone jack. If your sound card is disabled in Control Panel, it doesn’t appear in the list of installed devices, and you can’t enable it until you change your preferences. After enabling your headphone jack, you can set it as default for all audio or only for telecommunication audio, such as phone calls. Tips Warnings Writer Bio
