You're right, I'm sorry. It was late and I wasn't paying attention. Signature is updated.
To expand on things a bit, I was running 10.8.4 for quite a while with no problems. Vanilla install, running 816M, ran whatever audio patcher was standard then. Never upgraded to 10.8.5, went straight to 10.9. No audio device shows up, so I searched through the thread and found QUO-Audio-Update.pkg in post 645, I believe. Downloaded it and installed it for 10.9. and found audio works fine for about a minute, then it goes to asphyxiating robot hell. Unfortunately in my haste I did not back up the original manually before upgrading. If there's any more information I can provide, let me know. Thank you very much for replying.
