I just bought a new Mac Pro after spending over a year trying to fix audio/performance issues. Posting on stack exchange, apple forums, and endless googling proved fruitless. I tried every possible reset (nvram et al) and even created a new account (which seemed to help for a while until the issue came back after a month or so oddly). I had such a spark of hope when I saw this title. Alas, my fix for coreaudio HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload Audio still eludes me.
