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.

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

On 2025.04.27 I changed some settings then Shut Down.

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.

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.

Here are a few scatter charts of audiomxd memory growth after Start Up 2025-06-23 10:42AM. During this period, the audiomxd process has ended and begun twice.

When the audiomxd process ends, CPU Time and Ports each appear to have been set to zero.

When the process ends, Memory MAY NOT have been set to zero. That is, whatever is supposed to free allocated Memory when the audiomxd process ends, MAY NOT have freed all the memory that audiomxd allocated.

I'm logged out most of the time between sampling Activity Monitor measurements.

I have no speaker in my monitor and the Mac mini M4 Pro has only its internal speaker.

You're welcome, I hope it helps...?

When I check Activity Monitor on my Mac's, I see a few processes with 2,000+ open ports, but only 61 for audiomxd and I haven't shutdown or restarted in weeks.

No audio in place, except the Mac Mini internal speaker. My monitor is an Apple Pro Display XDR, which has no speaker or microphone.

The only other devices are a LaCie external backup drive, a Magic Mouse, and a Magic Keyboard.

Last year, I used Audacity (Intel architecture) to customize some songs to play at a near-constant volume, which helps when riding a motorcycle.

When I searched Activity Monitor for "Audacity" or "_audacity", nothing was found.

A possible cause of the growing audiomxd memory usage might be Siri, so I'll enable Siri for the next few days. [If Siri has to listen for "Hey Siri", then would Siri ask audiomxd to open a port? If so, then what happens if there is no microphone?]

I was logged out almost all of the time since yesterday. Are these the expected trends of audiomxd? My Mac Mini has only its internal speaker - no microphone or speaker on my display.

The AirPrint printer and scanner appear to work just as well without the Epson ET-4850 downloaded software. I set a periodic Reminder to check ink levels and to check for updated firmware.
