Describe the bug

I keep getting cracks/gaps while using the computer normally. I've found three specific instances where I can easily reproduce this. I use an app called Simplenote and whenever a note is saved, there is a crack/gap in the audio that is playing. Also, when using the cmd+F search feature in Firefox, I also get cracks whenever my prompt is not found. Finally, when screenshotting with cmd+shift+4 it also happens. I'm routing the audio like this: Blackhole -> DSP software -> Headphones.

So far, I've tested playback in Reaper and the JUCE AudioPluginHost and also tested recording in Audacity. The cracks don't happen when I send the audio directly to the headphones, that is why I believe the issue is with blackhole, but I'm available to do further testing.

Reproduction Steps

1. Set audio output device to blackhole
2. Set up a way to record or play the audio coming from blackhole
3. Perform any of the "triggers" described above

Expected Behavior

No cracks.
