Ubuntu 14.04 LTS
Mid 2007 mac mini
So I was up late watching and downloading a few shows from crunchyroll, the downloads hadn't finished by the time I went to bed and off peak net ends at 8am. Deluge has issues with the scheduler stopping a download sometimes so I decided to schedule a shutdown instead. In the terminal I entered:
Code:
sudo shutdown -h 07:59
to shut the computer off at 8am, when I turned the mac back on I had no audio on either the internal speakers or the headphone jack. I have checked the basics such as alsamixer and pulse audio having muted for some reason and whether the correct audio device was selected. The reason that I am posting in hardware is after several reboots I happened to notice that I could not hear the "Congratulations dumbass you bought a Mac" chime during EFI boot, which leads me to believe that it is a soundcard issue (fried?).

So the questions are: How do I determine whether this is a hardware/software issue, and why would a good shutdown cause this (versus yanking the plug or holding the power button, which I would understand). More info as needed
