I panicked. I reopened the panel. But the preset was gone. In its place was only “Living Room,” “Concert Hall,” “Bathroom,” “Stone Corridor,” and “Ska.” The edit button had vanished. The registry key had reset itself.
Sound returned. The crackle was gone. The speakers worked perfectly. In fact, everything sounded better than it ever had—clear, warm, detailed. The Realtek Audio Control Panel had reset itself to factory defaults, but it had also, somewhere in the process, fixed the underlying hardware glitch that had started all of this.

I stared at the screen. Then I unplugged my speakers. Plugged them back in. Restarted the PC. Nothing. I reinstalled the Realtek drivers from the motherboard manufacturer’s website—a 200 MB download that took forever on my mediocre connection. When the installation finished, a dialog box appeared.
