Thanks guys. Changing the output device, then changing it back, didn't work. Happily, the headphones work in Recovery Mode. As I type this, I play with volume; nothing. Suddenly, I think to check the Mute status… Yep, they were just muted! Everything is working again, and now I know what to look for if this happens again. I'm certain I didn't mute anything, so one of these audio programs must have done it somehow. Anyway, thanks for the help! > On Jan 24, 2015, at 1:57 PM, Grant Hardy <grantha...@outlook.com> wrote: > > You could try increasing the volume, as the speaker and headphone volumes are > controlled separately.
