Audio Skipping in recording and playback

Hey gang,

Ever since my Leopard install a few weeks ago, Soundtrack (2.0.1) has been skipping playback very bad. The audio cuts out for a split second every 2 seconds or so, and it's random and nasty sounding. Clearly this won't do. Ironically, myspace and other websites sites with media are also having the same problem.

anyone have an idea what the deal is?

I haven't changed my hardware config, but upggraded OS's, and everything had been running well under the previous OS. I notice a general sliggishness that I fed with more ram and it's still a problem. Before I start throwing more hardware the problem... your advice please.

ran diagnostics, everything seems to be working mormally,

what's next?

Dual G5, Mac OS X (10.5)

Couldn't agree with you more. I too am an Apple nut and use several of their products. Failed to mention in my post, that Logic and Garage band and all other audio programs are working fine. I even use the same loops to test and the problem lies with STP. Tried different audio sources including the internal speaker and no change. Apple techies are going to work on duplicating the issue and are supposed to call me back next week.

Same problem here quad G5, will not play clips in the browser, it stops and starts randomly, when playing anything in the timeline it glitches constantly. Also Garageband seems to be screwy too, it will not play at all. Logic, FCP, iTunes all work fine. Is the Garageband fault connected I wonder ?

I recently tried an archive and install of 10.5 and upgrade to 10.5.2 and re-install of STP, rather randomly Soundtrack didn't work immediately after the install, then just started working for a while last night, tonight back to the same problem

Update! Apple tech support called me back today. We have yet to resolve this issue. As of now I have installed Tiger on another drive and updated. Installed STP by itself and ran the app. Loops work fine and even tried the Ducati demo and it worked as well. Installed the rest of LogicStudio with exception of the content discs. Ran software update and launched STP again. Works fine. Problem has to be with Leopard! But wait, I did install STP on an iMac 20" G-5 with Leopard installed and it works fine. So could it be a Leopard and 2.3Dual Core related issue? Have to figure this one out.

Ok! 5:00a.m. blitz so I had to try it. Upgraded the Tiger drive to Leopard. After QT update was needed launched STP and we are back to having the same problem. I performed all the necessary updates one at a time, tried STP and loop playback is still messed up. Leaves me to believe that it is Leopard and my 2.3 Dual Core. I am in the process of installing the rest of Logic, except for the content discs, on the iMac that STP works fine on. I will also run the updates individually, try STP and try to pinpoint an update as the problem.

STP works fine on the iMac. Problem is that it only has 512mb of ram and it is the family computer. So it is not a fix for remedy for using STP. I would like for it to work on my studio MAC.

Im having the same issues as above. STP has skips and will only preview a selected audio file for a second before stopping.

Very frustrating. I am noticing a lot of unwanted quircs and issues in Leopard, but this one is a biggy. I have a quad G5 and 4 gigs of RAM running 10.5.2

hey DR999 did you trty that unplugging thang? i just installed FCPS2 and on my G5 Quad core 2.5 with 4GB ram and had the skipping and popping until i cleared the user cache and sys cache (using a nice little app called cocktail) shut down unplugged for 5 min (really 5 min!) and then reset the PRam on startup and now it's fine. i also had the loop issue with some loops playing badly, other not at all. this has also been resolved.

Thanks for the info. I just tried Cocktail and for some reason it would not empty neither cache file completely. Any help on that? Did do the unplug and pram restart and still have the same issue.

Update! Trying LogicStudio out on my G-4 MDD since we can't get STP to work on the G-5. As of now I have erased, installed, updated Leopard on one drive and Tiger on another. So far STP is working fine under Tiger. Will install and test under Leopard later and post results.

Feb 24, 2008 6:32 PM in response to DucRyder999

STP is working fine on the MDD G-4 running Leopard. Convinced now that it has to be a software/hardware issue with the G-5 2.3 DualCore.

Feb 25, 2008 5:09 AM in response to ProSuiteEditor

The problems with STP on my Quad G5 can teporarily be fixed by deleting system caches with an application like Cocktail, but the problems soon return. I have not managed to narrow down what is causing the conflict.

I have the same stuttering problem when playing back from Ableton Live on the Macbook Pro. iTunes playback is fine. I have two workarounds that work reliably for me:

1. Disable Airport.
2. Use an external USB audio device (i have a Line 6 Pod XT for this purpose).

In other words, the problem appears to be some combination of Airport and the internal sound device. Eliminate one of these two, and it works.

STP works fine on my Macs which have airport cards and are enabled. And the STP issue I am having with the G-5 DC 1.23 dose not have an airport card installed.

hey robert, DR999, i can second what has happened to you robert, as i just reloaded my project and wouldn't you know the popping issue has returned. what a drag. it seems also that the more i use STP the greater the problem becomes. i too am running 10.5.2 on my G5 quad core. tempted to go back and install on another partition under tiger. but i must say i am disappointed after dropping all that cash to buy FCS to be wrestling with these issues instead of working. a first for me with apple software! and all that after my girlfriend dumped me for her ex!

Resetting the PRAM on my Quad 2.5 G5 Resolved the audio skipping and playback issues I was having Garageband and Leopard 10.5.2
