Hey Flux. I've got the same thing (M1 Pro, 2021 model, 16GB, Monterey 12.0.1).

Any updates? Posting here cause it's easier than apple dev forums.

Thanks for the comment @rmhsilva. I haven't heard anything from Apple on this issue. I ended up replacing my mixer with a Rane SEVENTY which has a Serato controller built-in. The DS1 seems to work fine on the same hardware when it's Boot Camp'ed.

Sorry I don't have better news :(

I'd be interested to see if a newer DS1 has the same issue since I purchased mine in 2017.

No worries, thanks for the info. sudo killall coreaudiod helps temporarily, but not for long, so here's to hoping Apple do something!

Same issue here with a Schiit Modi 3+ plugged into a Belkin TB3 Pro Dock new CalDigit TS4. In my case, the issue went away after an update to 12.1 but returned after I replaced a RX 580 with a RX 6600 XT in my Razer Core X eGPU.

EDIT: Still exists on macOS 12.3.1 (21E258)
EDIT2: Still exists with Thunderbolt 3 hub connected to Topping EX5 DAC. At least the satisfaction of getting new kit is helping the frustration 🤷‍♂️
EDIT3: Finally a response from Apple in Feedback Assistant, ktraces sent.

Same experience with audio dropouts and getting IOAudioEngine[<private>]::pauseAudioEngine() in the logs. New MacBook Pro 14" M1 Pro connecting to a Topping E30 via a USB hub. Still happens if I connect directly, through any port.

This problem didn't happen on my combination of MacBook Air and Big Sur.

Was anybody able to figure out a fix for audio dropout issue? I'm using MacBook Pro M1 and seeing the same issue. very frustrating.
@djflux

Also found this https://old.reddit.com/r/macbookpro/comments/vluqp9/psa_suffering_from_your_m1_macbook_pro_making/. Seems to be a memory related issue. But don't know how to fix it.

@nickmacavoy
Copy link

No resolution for me. But I feel it happens less frequently 🤷 Once every two days with heavy all-day use of the MBP.

To resolve it, I open Audio Midi Setup and set the output to a different format from what it's on, 24bit 44.1KHz, which instantly resolves the issue, and then I switch it back again to 24bit 44.1KHz.

@alifarooq0

Thanks for the update @nickmacavoy. Same for me. It comes and goes. Really frustrating. I've definitely noticed it happening less frequently if the memory pressure is in the green and more frequent if its yellow.

Is there a way to override this behaviour by writing our own audio driver or something?

@nickmacavoy
Copy link

It's happening far more frequently now with Ventura – every few minutes at the moment compared with every few days previously with Monterey. This blows.

@alifarooq0
Copy link

Sad. I'm still on Monterey and its really bad on it as well. I have noticed that keeping memory in the green does help.

Have you tried https://github.com/mttrb/antipopd to keep the audio channel open, i find it helps a tiny bit.

There's got to be a way to fix this. Any driver engineers who can help fix this? some sort of audio driver magic? SOMEONE HALP.

MacBook Pro M1 16inch user here,
This happens to me as well, I'm using Scarlett 2i2 through a USB c hub from my dell monitor.

some say it's gone when plugging soundcard directly into USB c? can anyone confirm this?

When I'm frustrated I'll just put my switch my headphones port to the built-in port 😢

@ardasatata I've tried connecting my Steinberg UR22 directly to my M1 pro (no usb dongles in between) and I still hear it. What seems to help is reducing memory load. For instance, i've noticed i hear a lot more crackling if docker is running as opposed to when its not.

Has anyone tried upgrading to the latest OS, did that help?

I'm in Ventura 13.1, doesn't help that much.
yep, you're right keeping the memory pressure low did help. I've reduced my IntelliJ Idea heap size to 3084 from 4096 and I hardly hear any crackling since then.

I wonder why it doesn't happen on my 2016 intel MacBook pro with the same workload 😢

This is helpful @alifarooq0 and @ardasatata. My load is also in part attributable to Docker and IntelliJ (Rubymine / Webstorm), with other resources used by esbuild, postcss, Spotify, Mail, Slack plus various other non-development apps. I've long suspected file watching / IO usage as a cause?

My heap size for RubyMine is 1528MB. Looking at your screenshot above, I originally thought that any swap usage was an indicator for the crackling appeared, but I found cases where no swap was used and the crackling appeared.

I've had this issue for years after the 2018 Macbook redesigns. I'm using Traktor Kontrol S2 Mk3 as a sound card for Adam Audio monitors. There's an Apple forum post but there's no conclusion.

I know. sad. It's come a point where it's much easier to train my brain to ignore these popping sounds than to go on a hunt to find a solution for this.

The instance I posted about here was so bad my box was unusable. I eventually broke down and bought a mixer with a Serato interface built in (Rane Seventy). I still get the occasional drop out (once every hour or so if I’m DJing a long set) but barely noticeable. Still annoying that Apple won’t even acknowledge this problem’s existence 😔

I've sent a bunch of feedback within Feedback Assistance to help Apple remedy this – logs, ktraces, from many different instances and situations. I received a response from a person at Apple in February 2023 and sent them back some additional information.

I recommend you all submit New Feedback within Feedback Assistant to help push this along. Make sure that you include a ktrace while the stutters/drop-outs are happening as it'll give them as much information as possible to work with from the outset.

  1. Check if the problem still occurs. If so:
  2. Start a .ktrace capture file in Terminal.app before plugging in the device: sudo ktrace artrace -- -c
  3. Plug in the device.
