Sound dropping out

not sure whats going on, I'm getting a loud pop and then the sound goes out. Is this a sound card issue? What can I do to solve this problem?

It could be your audio interface... or not. Can you give us more details about your setup and audio interface ? Can you tell us when and how the problem occur ?

Thanks!

Christian

I'm using the core audio driver, when I change to another driver and switch back to the core audio it works again, but then every once in a while it pops and goes out again.

You didn't tell me what audio interface you are using. Did you mean you are using the built-in audio ?

If not, download and install the latest driver for your audio interface.

If you are using a Firewire or USB audio interface, make sure it is connected directly in your Mac.

Do you have the same problem in iTunes or GarageBand ?

yes I'm using the built in audio driver. no problems with itunes.

Hi K1,

What's your buffer I/O setting in Logic?

Logic Pro > Preferences > Audio

Rounik

its set to 1024

what about the sample rate for your project?

Does this happen regularly with other projects too?

Do you have any other application open?

Are you streaming the samples off your mac's HD?

What mac are you running logic on?

Have you done any maintenance on your mac - like repair permissions?

Cheers
Rounik

Sample rate is at 44100
Yeah it happens quit often even with other projects
Just running safari
Yes samples are from my mac HD
I'm running the new 2.4 ghz imac core duo
no haven't had any repair maybe I'm just running too much info and I need to freeze some tracks?

I think 2 things have a good chance of helping.

1. Maintaining your mac is v.important.

Quit all applications.

go to: Applications/Utilities/Disk Utilty

Select your mac's HD

Click on repair permissions

2. Turn off airport while using Logic and try quitting safari too.

hello
same issue here,my prime suspect was an east west instrument,no CPU saturation ,only a scary pop
and no sound
,i did what Rounik says (repair permissions)
an for now it works
how often do i have to do this procedure ?
what does this procedure do, exactly,?
can you explain to me please?
thank you Rounik
Hector

Hi Hector,

Glad it's helped.

Repair permissions is a maintenance procedure that many users do before and after installing applications, and I tend to do every two weeks or so. (The more frequently I run it, the less time it takes).

Here's a link to an Apple Support article about it:

http://docs.info.apple.com/article.html?artnum=25751

I don't have this issue of the popping sound so can't really say whether you will need to repair permission frequently or not. I Hope not, but next time you hear a pop, try quitting all other applications, if it's still a problem, restart Logic, if no joy, repair permissions and restart your mac.

Let me know how you get on.

Cheers

hi again Rounik
same thing again, i am almost sure that is somethig about PSP Vintage Warmer
because when the sound drops out the only channel that dont seems to get any sound was the out 1.2
and i had the VW on that , when i press bypass sound
comes again.i just upgrade logic 8.0.2
so do you have VW, ?
does any one has this problem ?
thank you
HECTOR

Hi Hector,

Unfortunately, I don't have PSP Vintage Warmer.

So, when you bypass the PSP VW plug-in the sound still drops out?

If so, try saving your project as a newly name project (File > Save project as...), then on the newly named project take out all instances of the PSP VW plug-in. Save the project and see if the problem persists.

It could make sense that this is related to 3rd party plug-ins.

Cheers
Rounik

Hi guys!

Here's a quote from pspaudioware website :"Limitations to demo versions: Depending on the product, either the processing stops every 30 sec for 1 sec or or you will hear permanent low level noise (at about -60dBFS typically) and occasional 1 sec noise every 20 sec (at below -30dBFS typically)."

Is your Vintage Warmer a demo version ?

hello again
christian ,i have purchase the VW,and is not and ordinary drop out ,in the beginning is a very loud pop
and then sound drops out,
rounik
if i bypass for now the problem goes away
if i enable again ,it works fine ,but later at any time
it happend again,and if i let the playhead playing, i cant hear

I can imagine! It's far from a good situation.

...Hector, are you using the zoom as your audio interface? If so, try using the built-in audio only...

Also, do contact PSP directly to see if they know of this situation.

Let us know how you get on.

Take care,

Rounik

no i dont use the zoom,i use the built in audio,
and i ve already contact PSP they tell me ,that if i
re insert the plugin usually works, ill see,what happen
thanks again for your concern
hector

my pleasure Hector. Good luck.
