Coreaudiod + other probs after re-install Yosemite 10.10.2

Question

Problem description:
coreaudiod (not responding) error.
  **I didn’t get the note several YEARS ago that TimeMachine would fill your drive until it used it all up, then start dropping b\u’s to save your last 1.44MB to write your last words to whomever one chooses.
  I learned that after I had overfilled my 2TB LaCieTB that was RAID Striped as well as my 1TB internal hard drive. The Short of it: Mac stopped booting and I had to boot from web and re-install Yosemite.  I do a lot of music and video recording/editing and lost FireWire connectivity to my FireStudio project A/D audio interface, started the coreaudiod, etc. error, and the inability to load my DAW (Digital Audio Work Station).
  Performance seems to still be pretty decent most of the time, but there are certain tasks that seem to have really slowed to a crawl: when transferring/compressing/importing large files. I am currently compressing the last folder on my LaCie to transfer to harddrive, a 231GB backup.db file.  it looks like it will be about a 2-3 hour ordeal.  From what i see in Activity Monitor, the CPU is hardly being used at all (11%+/-) and Memory has used 15.98 of 16GB Physical w/ 17.4GB Virtual.  I am definitely no guru, but that seems to be a pretty light load.  Almost like the OS is not using resources to an optimal maximum.
Attached is the Etrecheck.  Doesn't seem Activity Monitor wasn't showing me a lot of what Etrecheck did. It is reporting I need more RAM, maybe I'm wrong, but doesn't 16GB seem adequate?  Maybe one of the hung tasks is eating RAM?
Thanks for your input!
EtreCheck version: 2.1.8 (121)

Answer 1

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.  
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
