I get a crackly audio for about a second every 30 seconds to 5 minutes depending on the vector size when using one of my audio interfaces (RME Babyface or MOTU 8pre).

I use the interface as input and the output from the Mac for listening. Instead of outputting I get the same when I record with a sfrecord object. So my patch is as simple as possible: an input, a fader, the sfrecord or an output.

It does not happen when I use the internal mike or the built in input. Also o no problem in Logic.

My system is OS 10.10.4, MacBook Pro 16GB with SSD.

I have the newest drivers for the interfaces and tried all combinations of vector sizes, overdrive and cpu optimize.

I get the same problem using Max 6 and 7 and also on my older MacBook Pro with OS 10.6.8

I wonder that none has reported the problem so far. Can anyone reproduce it?

intermittent-crackly-audio-using-external-audio-interfaces

it seems the problem is solved: I used different input and output devices in Audio Status. I payed no attention to it as my original patch did only record and not output.

Can someone explain, why one must use the same device and what causes the distortion?

I also noticed that the adstatus object can list the input devices (by attributes "option 0") but there seem not to be any possibility to indicate the chosen output device apart from the Audio Status window.
