audiomxd high memory allocation port allocation CPU time

Apple Community.

audiomxd Memory and CPU screenshots

In February 2025, I bought a Mac Mini then migrated from my iMac (Retina 5K, 27-inch, Late 2015) to my current Mac Mini M4 Pro. The Mac Mini is probably running Rosetta.

About: Mac Mini 2024 M4 Pro. 64 GB Memory. macOS Sequoia 15.4.1. Apple Pro Display XDR with NO MICROPHONE and NO SPEAKER. No Audio app. No VST plugins.

The Apple Pro Display XDR is connected with an Apple Thunderbolt 5 cable to one of the three Thunderbolt 5 ports in back.

An external Lacie backup drive is connected with an Apple Thunderbolt 4 cable to one of the three Thunderbolt 5 ports in back. Time Machine backs up the Mac Mini M4 Pro once a week.

Feedback - Mac mini - Apple

Feedback report 6 on the audiomdx memory leak.

2025-04-26 12.23PM 1.36 GB 102,386 Ports.

2025-04-27 10.14AM 1.52 GB 130,067 Ports.

On 2025.04.27 I changed some settings then Shut Down.

Apple > System Settings > Apple Intelligence and Siri >

Apple Intelligence: OFF

Siri: OFF

Adobe Elements 2021 Organizer > Preferences > Media-Analysis >

Generate Auto Creations: OFF.

On 2025.04.29 I uninstalled an Adobe desktop app the Shut Down.

Uninstall the Creative Cloud desktop app

On 25.05.02 I changed some settings then Shut Down.

On 2025.05.03 here are Activity Monitor screenshots of CPU Time and of Memory Allocation.

2025.05.03 12:49 PM audiomxd CPU Time 20:02:08.10

2025.05.03 12:49 PM audiomxd Memory 770.2 MB 39,904 Ports.

Usually, I Logout after each time I use the Mac Mini.

Occasionally, I only Lock the Screen.

Why is Memory allocated, but not freed after closing the app that was using the Memory?

Why does audiomxd need an ever-increasing Memory Allocation to manage the internal speaker on a Mac Mini? I have no external speaker or microphone.

I just now ran EtreCheckPro, and no malware was found. Here are screenshots of Activity Monitor.

Preferences are still set to the following:

Apple Intelligence: OFF

Show items In Stage Manager: Uncheck

Uninstall the Creative Cloud desktop app

Click wallpaper to reveal desktop change to Only in Stage Manager

Drag Windows to screen edges to tile: ON

Drag Windows to menu bar to fill screen: OFF

Activity Monitor provides an important capability in identification of apps that are experiencing concerning trends in CPU Time, memory usage, and ports.

EtreCheckPro is very useful in identification and removal of likely suspects which may be causing the concerning trends.

Thank you, BDAqua for troubleshooting this problem.

When the Mac Mini M4 Pro macOS 15.5 was in SLEEP or SCREEN LOCK, then CPU increased, but the Ports remained constant. Any Memory increase was not large enough to be indicated.

I power-cycled my AirPrint printer, because it was offline due to unknown causes. It had the latest firmware.
