While installing a second 660 Ti, my speakers began making an obnoxious buzzing. I turned my speakers off for the meantime, until I finally got my SLI configuration working. Now, when I plugged my speakers back in and made sure they were turned on, my speakers show up as "Not plugged in". I have tried plugging the audio out cable into my keyboard, which allowed it to show up as plugged in briefly, but it still would not produce any more than buzzing. The speakers work fine if I plug them into another computer or even phone. I am using a Logitech X-530 5.1 Speaker system.

I've tried- I even disabled my NVIDIA sound drivers in the device manager. Realtek High Definition Audio only appears as "Not plugged in", despite being plugged in.
