audiomxd high cpu memory mac mini 4 software feb 2025

Tried some old stuff about the library/preferences/audio .... nooo workeeee

The real issue, I plugged external speakers into my BENQ display earphone plug instead of the FRONT earphone plug on the MAC mini4 . The sound works fine (selected BENQ output), with outrageous CPU and memory degradation.

The FIX was to switch to the front earphone plug on the MAC mini4.

Apple, you have an issue with 'sound' going to a display interface.

Mac mini, macOS 15.3

Apple will neither see nore respond to posts made in these user-to-user forums. If you wish to place this before an Apple employee, I invite you to use this feedback link:

BENQ GL2780 . HDMI connection.

CPU usage was above 113 hours. now its just 11 hours.

Memory is still allocated, guess they don't teach freeing memory anymore. Sitting at 1.02 GB.

info from activity monitor

That doesn't tell us what is using CPU and Memory.

Plus you need to restart macOS to totally free up allocated memory.

Take 2 screenshots of the Activity Monitor. 1 with CPU selected and 1 with the Memory selected, then post those screenshots using the Image Insertion tool below.

I just witnessed this same behavior on a 2023 iMac (Identifiers: iMac (24", M3 2023) - MQRQ3LL/A* - Mac15,5 - A2873 - 8206*). macOS 15.3.2 (24D81). I rebooted my iMac, the problem did not reappear.

My AirPod Pro 2 case containing my AirPods was in one port. I had just attached my iPad Pro (3rd Gen), and awakened the iMac from sleep via TouchID. I first noticed upon opening a Finder window, I could not select items in the Favorites list. But I could open other apps via the Dock. Starting a terminal window I invoked Top and saw audiomxd using 100%+ CPU. I rebooted the iMac, and behavior is back to normal.
