Sound isn't playing on startup or any other time.
I'm not seeing the red glow from the headphone jack that I've seen mentioned in certain cases of this failure. Though I have noticed an awful lot of cases that at least sound like mine (sudden blanket audio failure.)
Any thoughts on how to move forward with this one?
