Question

Why does my sound turned distorted after 2/3 minutes of using an audio interface?

I brought a brand new audio interface and started using it with MainStage. Every 3-4 seconds, there is a light click/pop on the output audio. This does not happen when I am not using an interface and just using the computer output. After 2/3 minutes, the sound started to get muffled and distorted, and eventually just gives out and all audio turns to a distorted noise. Here is a video i recorded, it is most evident in the last 5 seconds or so. I tried increasing the buffer size from 128 to 256 and eventually 512, but it still happens.

What interface are you using? Have you updated the driver from the manufacturer's website?

Behringer FCA610. It says on the Behringer website, for Mac there is no driver required.

Is it connected to the Mac via Firewire or USB? Have you tried using a different cable?

It is connected to my Macbook via USB. It came with a Firewire cable, but my computer is a newer Macbook and has two Thunderbolt ports but no Firewire. If the USB does not work after a couple more tries, I guess I will have to try buying an adapter.

This sounds like an issue, which can occur, if the input device is different to the output device. Try to select the the FCA 610 as input and output device. If you mix it like internal mic as input device and FCA610 as output device, they might go out of sync and things start to happen.

Best,

Cool! Thanks for marking the answer as a solution. More than often, solutions are posted here, but the original poster doesn't seem to care. That's sad for those, who have similar problems and seek for a solution. (I don't mind collecting a view points, though ... ;-))

Cheers,

Hi there, I know it's been a while since but I'm having this problem that you were having. Do you have an idea what you did to fix this?
