    Exclamation No Audio Devices Found
    The other day, I was attempting to play music from my headphones (using headphone jack) and my bluetooth headphones at the same time. I opened Audio MIDI Setup tried to make it work. Eventually, it froze and now I get the error of the circle with the diagonal line through it anytime I try to change the volume. Also, System Preferences does not work at all, and every other application runs slow and I get the pinwheel very often. When I look at Audio MIDI Setup now it says no audio devices and I cannot play sound. I have tried entering the "sudo killall coreaudiod" command in terminal and restarting my computer using alt+command+p+r. When I try this it makes the classic apple startup noise, but then the sound still does not work. Any idea what is going on? Any suggestions would be appreciated.

    Did you use the PRAM reset properly? e.g. holding it down until it restarts the 2nd time?

    You might also want to try a SMC reset.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    I did do the PRAM rest properly, and I just tried the SMC reset, but it also didn't fix the problem. Thanks anyways.
