Hi there, I wanted to report a weird bug that I’m experiencing with Plexamp 3.4.1 on macOS: when I set the output device to an external audio interface (Motu M2 in this case), the audio stutters constantly, in a very choppy fashion (don’t know how else to describe it). Playback is entirely fine via…

Exact same thing happens to me. Im using an EDIROL firewire interface and, as soon as I get any notification alert from another program (which does sound correctly) Plexamp will start to make this cracking noise and it wont recover. The desktop Plex App does not suffer from this.

reached out in a linked thread to see if we can figure out what’s going on.

@elan Can you share the linked thread? I’d like to contribute if I can.

@elan So far so good! I will keep testing.
