Feb 26, 2014 11:29 AM in response to The Art Of Soundby stratquebec,Here's my 10.9.2 report
iMac Specs:
iMac 27 inches , late 2012, Processor 3,4 GHz Intel Core i7, NVIDIA GeForce GTX 680MX 2048 Mo, OS X Mavericks 10.9.2
Test using a Focusrite Saffire Le Firewire 400 connected in the thunderbolt port using a thunderbolt adaptor through a firewire 800/400 cable.
Tests done with Safari 7.0.1 (32 bit) and QuickTime 10.3 (64 bit).
Here are the tests:
I launch Safari 7.0.1 (32 bit ) watching the actual Apple.com ad. (http://www.apple.com/#video-tv-spot)
The ad’s audio is nice.
Test 1:
I launch Garageband 10.0.1, (latest version) the ad’s audio plays correctly.
With 10.9.1 the audio was full of clicks and pops. I had to quit Garageband for the ad’s audio to play back correctly.
Test 2:
I launch Logic Pro 9.1.8 (latest Logic 9 version in 32 bit mode, same test in 64 bit mode), the ad’s audio is distorted if I set the Logic I/O buffer to 32 samples. The ad’s audio plays correctly (or with just a littles clicks here and there) using a 64 samples I/O buffer.
With 10.9.1 the audio was full of clicks and pops. I had to quit Logic for the ad’s audio to play back correctly.
If I set back the Logic’s I/O buffer to 32 samples the audio is distorted but get back to normal the moment I quit Logic Pro.
Test 3:
I launch Quicktime 10.3 (latest version) , the ad’s audio has just a littles clicks here and there.
I open a .mov file in Quicktime and its audio is full of clicks and pops.
I quit Quicktime and the ad’s audio plays correctly.
Test 4:
I relaunch Quicktime the ad’s audio is full ok clicks and pops.
I quit Safari and the Quicktime audio has still some clicks here and there.
In short 10.9.2 is better but not perfect
But, look at this! Either with 10.9.1 or 10.9.2, if I set an aggregate device and set the Logic and Garageband audio preferences to use it, then I don’t have any audio problem at all (so far) and best of all, I can set back the Logic’s I/O buffer to 32 samples!
So I’m done fighting those **** Mavericks audio issues.

Feb 26, 2014 1:28 PM in response to stratquebecby Wound,Stratquebec, I think I follow you.
Regarding the aggregate I'm a little lost though...
So you had the Saffire in use during the tests 1 to 4 with issues.
So what was the aggregate device?
-
Feb 26, 2014 2:00 PM in response to Woundby stratquebec,My aggregate device is my Saffire Le combined with the iMac's built-in audio, simply.
Here's how to create an aggregate device: http://support.apple.com/kb/HT3956

Feb 26, 2014 2:28 PM in response to Woundby stratquebec,"So you had the Saffire in use during the tests 1 to 4 with issues."?
To sum up: Using the Saffire Le alone:
- Big issues under 10.9.1
- Less important issues under 10.9.2
No issues under 10.9.2 if an aggregate device is set up and then selected in Logic or GarageBand.
Minor issues under 10.9.1 if an aggregate device is set up and then selected in Logic or GarageBand.

Feb 26, 2014 7:51 PM in response to stratquebecby Wound,Thanks for explaining that.
I've never done the aggregate thing.
This is good news ( though would be good if they got it working without aggregation).

Feb 27, 2014 2:35 AM in response to The Art Of Soundby _grigor_,Hello,
I got late 2013 iMac :
- 3.5GHz Intel Core i7
- 8 GB RAM
- HD 1 TB Fusion Drive
- OS X 10.9 Mavericks
- Focusrite Saffire PRO 24 DSP
After playing an audio in 10.9.1 (from any source : iTunes , Garageband, Safari , YouTube ) for a while ( few seconds to few minutes) the audio completely drops out.
After updating OS X to 10.9.2 everything works perfect - few hours of recording and playback without any problems
Cheers

Feb 27, 2014 8:40 AM in response to stratquebecby stratquebec,Correction: In my post above we should read:
But, look at this! Either with 10.9.1 or 10.9.2, if I set an aggregate device and set the Logic and Garageband audio preferences to
the Saffire Le (same test with the Digidesign MBox2 Pro)
, then I don’t have any audio problem at all (so far) and best of all, I can set back the Logic’s I/O buffer to 32 samples!
So I’m done fighting those **** Mavericks audio issues.
Sorry for the confusion!

Feb 27, 2014 3:25 PM in response to The Art Of Soundby Enver Chango,iMac late 2013
3tb fusion drive
Before: Clicks, pops and intermittent distortion while playback using my Line6 KB37 audio interface. Youtube, itunes, logic pro X, garageband etc were affected.
After update: All above were fixed. Not a single pop since updating.
Though i must admit i haven't tested recording audio extensively yet, but it looks promising indeed...
Thanks to everybody who followed up and brought some order through these dark months.

Feb 28, 2014 11:37 AM in response to Enver Changoby Foveus,I'm pleased to report that 10.9.2 has thus far fixed all of my issues. I have a late 2013 iMac with 3TB fusion drive and am using a RME Fireface UFX (firewire to thunderbolt adapter) as well as a Burson HA160 headphone amp/external DAC (USB). Before 10.9.2 both were unuseable due to consistent pops, clicks, distortions dropouts etc. I've used both to listen to spotify, iTunes and youtube and to record audio into logic x (UFX) and thus far there have been no obvious issues since updating the OS. Fingers crossed ...

Feb 28, 2014 9:09 PM in response to The Art Of Soundby NoelEiffe,A long odyssey appears to have ended.
I had "un-fusioned" my 3TB fusion drive. After the 10.9.2 update, I re-fusioned, reinstalled, and all seems to be performing well. (Still have USB3 port issues though; e.g., my 2 Seagate usb3 external drives will not boot off the on-system ports...had to run the drive through a USB2 hub to get them to boot the machine. I also have to run my Steinberg UR824 through a hub as well. Argh...)
Anyway, audio problems appear to be sorted out, and I had them bad.
For those who need to do this, the "re-fusioning" is easy. Boot to the recovery partition by holding Cmd-R during boot. Open Disk Utility, and it will be showing a problem. Click on the drive and it says, "Your fusion drive is not installed properly. Would you like to fix this problem?"
BE WARNED: This is a destructive change, so you better have backups.
After you do it, if sets the drive back to "MacIntosh HD" with no bootable os partition on it. At that point, I booted off my external drive (in a USB2 hub of course), and then just ran SuperDuper to clone it back to the fusion drive. (That took almost 24 hours to complete, but once it's done, it was a simple reboot and all is well.)
What a nuisance and soul draining, disheartening Apple experience this has been. But on the other hand, it appears to be fixed.
Thanks to all who've shared the info we've needed to get through this, esp AoS.

Feb 28, 2014 10:35 PM in response to NoelEiffeby The Art Of Sound,You are welcome NoelEiffe.....
It does appear, from those here and elsewhere, plus those people who have been working with me directly... that the problem with the 2013 iMacs with a FD fitted audio issues, has indeed been fixed at last....
Thank you all for the feedback that assisted in tracking down and identifing the real issue and also helped provide a temporary workaround in the meantime...
Much appreciated!
Cheers..

Mar 1, 2014 9:00 AM in response to The Art Of Soundby ColinInLa,NO! 10.9.2 has done nothing to repair sync and 'clicking' issues either in YouTube or .mov or m4v. Aren't these updates beta tested? It's totally unacceptable.

Mar 1, 2014 9:40 AM in response to ColinInLaby stratquebec,Give all your specs please: Mac ?, Logic Version, Audio interface, cables, adaptors etc... All please!

Mar 1, 2014 9:55 AM in response to The Art Of Soundby NoelEiffe,Actually, I have to rescind my machine's clean bill of health after a bit more testing.
The extreme decimation of sound is gone, where sound gets nastily pixelated, but I am getting quite a bit of popping and noise in recording and playback in Logic Pro X and FCPx as well.
@#&$^&@. This machine is cursed.
It is: Late 2013, i7, 3TB Fusion disaster drive, 16gb ram.

Mar 1, 2014 10:15 AM in response to NoelEiffeby The Art Of Sound,Scott,
Sorry to hear this...
The feedback I am getting is mainly from those with FW devices.. and for those people, in every case so far... 10.9.2 has resolved all audio issues... after extensive testing by them.
Maybe this is related to the USB2-3 issue in some way?
