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.
