10.8.4 introduced incessant audio glitch

Treating me rudely when I'm intending to be helpful is a sure way to convince me to stop.

It's happening to me to, using Spotify and also playing audio back within Safari and Chrome (Rdio and Spotify web).

I just started reading about this issue. I'm not having any fan issues (like some are reporting with 10.8.4), but for grins I just opened up the Console and saw that I too have the "coreaudiod: Disabled . . ." and "coreaudiod: Enabled . . ." messages in groupings of anywhere from about 4 to 10-12 of the messages, and I'm not doing anything but reading Yahoo news or visiting other news websites. I can go back into the console and see that it was occurring while I wasn't even at my computer an hour ago, although I had a couple web pages open while away (e.g., my.Yahoo.com, eBay.com). I have a fairly vanilla system, with no 3rd-party software like Little Snitch running in the background, no virus protection software, etc. iTunes is *not* open at all, and no audio has been played. I wouldn't be surprised if this turns out to be related to Adobe Flash . . . those annoying ads all over web pages that have ads running, but no sound unless you click on the ads to listen to them. That's my 2 cents.

I'm affected by this too on a Retina MacBook Pro 15.

It could be one of multiple things that are triggering these messages from coreaudiod, which I'm seeing on my Flash-less systems. To me they look and behave like messages intended for debugging purposes that Apple forgot to disable. Non-debugging messages this repetitive are typically the sign of a problem and will stop once it's been fixed. Unless coreaudiod is misbehaving it shouldn't be console-spamming like this.

I am getting a sound alert corresponding to every time I get the message "....because audio IO is active" OR "...because audio IO is inactive"

Worse still, these messages occur in pairs just a second apart: active then inactive, bang-bang. I get a pair of messages -- and sound alert for each one -- about every 2-4 minutes.

Ruins listening to anything!

Is there any way to disable the sound alert that corresponds to the message?

And I should add the messages do not appear to correspond to a specific program.

Did you try what Linc Davis suggested in his last post?

Try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

Just a note...while watching the Console, I pushed Play (F8 on my MacBook Pro) in iTunes 11.0.4 (4) and the log writes, "6/17/13 11:09:05.541 PM coreaudiod[154]: Disabled automatic stack shots because audio IO is active"

When I push Pause (F8 again), it writes to the log, "6/17/13 11:09:11.218 PM coreaudiod[154]: Enabled automatic stack shots because audio IO is inactive"

Console matched my play/pause sequence, no matter how long between each push of the button. So I'm guessing the quick messages piggybacked on each other are some sort of system sound or short ping of a sound. The disabled automatic stack shots stayed disabled while my song played and then flipped to Enabled when the audio ended/paused.

Hope this helps.

I'm encountering issues but different ones in the latest OS & iTunes versions...
iTunes will drop the audio but the play-head will continue to run as if all is fine & it's outputting audio.

Pressing pause & play brings the audio back up straight away.

Any clues on what this is all about?

my system is updated

OS X 10.8.4 (12E55)

log is:

/Library/Audio/Plug-Ins/Components/A52Codec.component

/Library/Audio/Plug-Ins/HAL/AirPlay.driver

/Library/Audio/Plug-Ins/HAL/iSightAudio.driver

System log is very spammed by coreaudiod

Please somebody can help?

I have a fresh install of 10.8.4 and get

/Library/Audio/Plug-Ins/HAL/AirPlay.driver

/Library/Audio/Plug-Ins/HAL/iSightAudio.driver

in the log. No audible issues, though.

I'm seeing this as well...annoying to see my logs spammed with this...
