iMac Sound Issues Post Upgrade
Posted on Sunday, 04 May 2008 18:42I recently faced a conundrum after upgrading the memory on my old iMac G5.
After the upgrade, I was greeted by silence. A quick check in Leopards preferences indicated that there was no audio hardware present, a check in Apple System Profiler confirmed the same.
My first thought was that I'd knocked a card or cable while inserting the DIMM. A search online indicated that this was a real posibility. I was dreading pulling the plastic monster apart.
Before breaking out the toolkit, I thought I'd take a chance on an old friend, Apple + Alt + P + R.
I'd dabbled with macs on / off for the last 10 years or so, and you pick up a few tricks, resetting the pram and the vram, rebuilding the desktop etc. Since my g3 iBook I can't recall ever using those tricks.
With nothing to lose I booted up holding down those four keys and on the second boot, chimes! I was a bit surprised it worked, and puzzled as to why it worked but I'm glad it did.
