I switch between my headset and my speakers a lot, and today when I switched back to my headset, my microphone's recording was very quiet. Before today everything worked fine. I thought it was a minor problem so I just unplugged my headset. But after I unplugged it, it still showed up as plugged in playback/recording devices list. I looked in the Realtek Audio Manager and it said it was also still plugged in. I tried un-installing it in the audio manager but it still showed up as plugged in. The only way the mic would work decently is if I turn on microphone boost, but in return the static noise is loud. Please help.
