10.8.4 introduced incessant audio glitch

During iTunes playback, everytime the audio squawks and drops out for a second, the following spew appears in the console:

6/5/13 8:39:17.533 PM coreaudiod[171]: Enabled automatic stack shots because audio IO is inactive

6/5/13 8:39:22.724 PM coreaudiod[171]: Disabled automatic stack shots because audio IO is active

6/5/13 8:39:43.297 PM coreaudiod[171]: Enabled automatic stack shots because audio IO is inactive

6/5/13 8:40:50.885 PM coreaudiod[171]: Disabled automatic stack shots because audio IO is active

6/5/13 8:41:45.525 PM coreaudiod[171]: Enabled automatic stack shots because audio IO is inactive

6/5/13 8:41:45.884 PM coreaudiod[171]: Disabled automatic stack shots because audio IO is active

6/5/13 8:41:51.503 PM coreaudiod[171]: Enabled automatic stack shots because audio IO is inactive

I've installed the freshest audio drivers to no avail

That pair of mesages appears far more often on my 10.8.4 systems than when iTunes is active, e.g. during browsing with Safari. Quite annoying.

I'm seeing the same diagnostic messages, but not having audio playback issues.

What audio interface are you using?

Are you running the latest version of iTunes (11.0.4)?

Back up all data.

Triple-click anywhere in the line below to select it:

ls -d {,/}L*/Aud*/P*/*/* | open -f -a TextEdit

Copy the selected text to the Clipboard (command-C).

Launch the Terminal 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. Click Utilities, then Terminal in the icon grid.

Paste into the Terminal window (command-V).

A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

No playback issues here either (with iTunes 11.0.4). I can easily trigger the messages on my 2007 MBP, 2009 mini, and 2001 MBA just by opening Terminal and typing Control-G. No extra audio drivers installed. Still want to test under a generic Guest account, hopefully determining if it's a system-wide problem or something specific with my regular account. If likely system-wide I'll restart in Safe Mode and do more testing. Finally, I can test while booted from another volume that only has Apple software installed, eliminating the possibility of it being related to any third-party software.

Move all those third-party components out temporarily, then reboot and test. You're testing for the audio artifact, not the log messages which are unimportant.

It's been pointed out to me on Ask Different that the new behaviour as a result of setting AllowStackShotsDuringIO to true may not be ideal, however. It's up to you whether you're fine with not having the messages displayed but the possibility of having a stackshot happen while audio I/O is occuring or if you don't care and would rather just have the flood of messages to the log stopped.
