Been listening through my iPhone hooked up through the USB on my Mac Pro, and have not heard it once in over a half hour of critical listening! This definitely points to an OS problem to me. Obviously the rear board, and sound chips are fine. No problem so far through the front headphone jack either.
Typical for Apple really...
The only time in the past years and years of reading and looking that Apple seemed to care was when their MB batteries were burning people. And I suppose then only to stave off law-suits. <shrug> After 6 to 8 years of ecologists complaining loudly I saw them recently speak a little green. But yeah, other than those two I've never seen Apple show very much concern over an "issue" - especially compatibility and performance issues.
I have not been able to replicate this. I listened to an Audio CD yesterday with a runtime of 1 hour and 2 minutes, and played it about 4 times. I was using the system while it was playing, with a few VMs running and I intentionally allowed the system to run low on memory and start paging to see if it would affect it. Never heard it skip one time.
System:
2012 Mac Pro 12-core 3.06
10GB RAM (yes 10GB
- other RAM is removed from machine at the moment)
512GB OEM Apple SSD
ATI 5780
Dual SuperDrives
Audio output to Bose Companion 2 speakers
OS X 10.9 Developer Preview 5 (now 6).
Audio player - iTunes 11.1 beta
CD was a pressed MFSL 24k gold CD that has been well used.

I have found the only time it does not happen is when I play anything (including a steady tone through garage band. Then it plays fine. That pretty much rules out the hardware as far as I'm concerned! The computer must be using the same D/A converter, and is definitely using the same analog outs. Still nothing from Apple! Guess their to busy making money! I think this will be my last Apple computer.
No, it's the software, period.
10.6.8 did not have this problem at all. Ever.
10.7 and 10.8 are so shaky in this regard that damned near any system load will trip up iTunes and/or the audio stream. Like I've said before, there appears to be two issues at play- 1) the momentary skipping that most people notice, and 2) flat out second-long pauses when the disk I/O is under heavy load.
It is hilariously easy to provoke either, which is absolutely pathetic considering how flagship iTunes is supposed to be. I'm wondering if Apple can do anything right anymore, given that I can't even playback my ALAC library without some skipping throughout the day (or 5 second long pauses when something disk intensive is happening).
My guess is that it all boils down to a bug in Core Audio, and 10.7/10.8's super ****** disk scheduling. Who knows when they'll fix it, I've only filed 12 bug reports on this exact same issue now.

My 2010 3.2 quad with 24GB RAM also drops audio. ML totally bogs down when I do a disk intensive operation. Photoshop building previews while Aperture saves to a backup? Just not possible. Open iPhoto while Photoshop reads a big folder? Beach ball, beach ball beach ball.
I'm looking forward to Mavericks to see if it is going to restore a feel of a powerful, responsive OS. Every so often I boot up on SL just to see what it is like to press a key and have something instantly happen on the screen.
This sounds alot like the problem I am having See Thread and as of yet is still unresolved. Although I have not updated that thread as I am waiting for it to be resolved. The latest is that Apple should be sending a new Mac Pro out to me when they are available.
Hmmm....but maybe it is software after all?

Dunno if that's the same problem.
The problem we are experiencing is OS X specific, mostly due to Apple's shoddy programming in 10.7 and 10.8. Windows and Linux don't experience the same issue (I've tested things extensively). It's only under OS X.

Are you seeing this on playing Apple Lossless files in addition to a CDDA disc?
To be honest with you, I've never tried. All my CDs go through XLD's secure ripper and land up in my iTunes library, with the disks going back into the closet. I'll dig one out tomorrow and see.

From what you folks wrote here, it seems that this may be more OSX or iTunes related or both.
Perhaps using another media player is in order until Apple decides to take off their Midas mask and do something about the problem.
VLC
MPlayerx
JRivers
...just to name a few that might be reasonable enough to use.
I have found all sorts of quirks with iTunes and I admit I liked it a couple of version/upgrades back.

interesting- I've never had this problem with my 2008 MP. i've been running 10.8 on it since it came out, 10.8.5's on it now. my iTunes library is mostly lossless but there's a few album's worth of 96k/24bit wave files in there and those never skip, either. I don't keep my itunes library on that machine though- the library lives on a mac mini and I use home sharing to access it from the 2008 MP.
the MP's system audio output is set to 96k/24bit. i generally use the toslink out on the back, but occasionally I use an old firewire Apogee Duet with the latest version of Maestro.

Thanks for staying on top of this and keeping us all updated. I had a momentary lapse the other day when I went to try out iTunes Radio, only to be reminded of it on the very first song. My Pro is fast becoming a podcast-only listening device.
