I even spoke with RME since I initially thought it was exclusive to their driver.
You can avoid it by running a higher CoreAudio buffer sample, but if the CPU load is high enough on your audio process, it can still conflict and overload.Īpple did respond for additional diagnostic info, and I also spoke with Logic support and gave them the same details. So when a low latency single threaded coreaudio event happens at the same time, you get the skipped cycle error, and then the coreaudio stream can overload producing the audio dropout. However, the Battery Manager gets priority based on its Command checks. When these are single threaded, like the polling method the Battery Manager uses for its CommandGate checks, or running the active live track in Logic, they exist on the same core, and basically get lined up to run in the WorkLoop. The IOKit has an associated WorkLoop which is basically a que of background tasks it runs.

The AppleSmartBatteryManager driver is part of the IOKit framework, as is CoreAudio. I've gotten to the root of the issue and submitted an Apple Dev Bug Report. But as with all things, the more eyes that get on this the more likely a fix. I’ve started a bug report through Apple developer for Mojave. It always puts the active track the same as the kernel level processes. Changing the processing core setting in Logic has no effect. Depending on project size this can occur at all CoreAudio buffer settings. I’ve tested with the internal MBP sound, and RME Babyface Pro, and a Digigrid D Ethernet Audio Interface. On my tested systems I get a CoreAudio overload event more than 90% of the time. You should see the AppleSmartBatteryManager poll start, then immediately restart, then some of its command checks, and if you had a dropout, a CoreAudio overload message(s). Return to the System Console and search those event times. Repeat a few more min cycles noting if you got a glitch audio dropout.ħ. You should encounter a sizable cpu spike, and high potential for a audio drop out.

Start playing the Alchemy patch live as the active track and watch CPU meter as time approaches the AppleSmartBatteryManager poll start.Ħ. Open your System Pref Time and Date leave that viewable to track time.ĥ. Open your OSX Console App and search Battery and note the time the AppleSmartBatteryManager start poll event occurs.Ĥ. Double click your Logic CPU meter to get floating window showing all cores.ģ. I’ve also used Keyscape, Kontakt libraries, and uh-e synths with similar results.ģ. Create Instrument Track with Alchemy Bowed Metal Space patch (or some other cpu intensive plugin) I usually add in a default chromaverb fx to get the cpu on live play over 50%. I have tested Ableton and Cubase and can reproduce the overload events.Ģ.

I use Logic Pro to demonstrate it since its CPU meter isn’t averaged like in Ableton 10 or Cubase 9.5.3.
Here are the steps if you don’t want to watch the video. There I also reproduce it within High Sierra: YouTube I’ve created a couple videos detailing my steps, this being the latest with Mojave, the other video link is in its YouTube description. Typically because most pro audio applications are putting your active track on the same core as the background kernel processes. This event creates a CPU spike that can overload your CoreAudio and cause a dropout/glitch sound. Regardless of being plugged into the AC adapter. On my systems, it runs a diagnostic poll of the battery status every 60 seconds. The issue involves a background kernel process called the AppleSmartBatteryManager. I’ve tested a new MBP 2018 with the i9 cpu, 32GB ram, 1TB HDD, and a late 2013 MBP & 2011 MBP. I’m looking for other MacBook Pro users to verify a CoreAudio overload bug that occurs in both High Sierra 10.13.6 and the latest Mojave Beta 10.14.
