I had to reinstall OS X Lion Server 10.7 on my Mac Mini late 2011 due to partition and boot record corruption. Since reinstalling I have not have sound. The only sound device that shows under Utilities||Sound is "Internal Speaker". Previously, "Headphones" also appeared. I have a Harman Kardon Soundsticks 2.1 sound system. It has only one sound connector. I always plugged it into the green port on the Mini. It worked fine.
Since reinstalling I have no sound at all.
Any ideas out there ? Solutions ?
I have been through the CmdPR deal, reinstalled OS X Lion Server, - all to no avail
