Inicio MacOS Monterey Sound Bug

The support article is intended for macOS users that are on macOS Monterey. We learned that macOS Monterey has a bug that is impacting all OS level mute functionality. The bug predominantly appears when the microphone connected to the computer also comprises of an earpiece. This means that most headsets and Bluetooth wireless headsets are immediately impacted, but other microphones may be impacted as well. 

Issue:

The MuteMe-Client software interfaces with the operating system to control different microphones that are connected. The operating system classifies devices as either a input (microphone) or output (speaker), and then gives granular control to various applications to interface with those devices. In the latest build of macOS Monterey there was a change made to how devices are classified (it is clearly a bug), that change on the backend of the operating system is causing all types of issues for any device that exercised control over headsets or microphones. We know this is a bug in macOS because default tools within the operating system are broken as well. 

Steps to reproduce on macOS Monterey without MuteMe software:

  1.  Connect any bluetooth headset to the computer.
  2. Open default "audio MIDI setup" application which is a default macOS application. 
  3. Find the headset you connected via bluetooth and find the input pane it might show up as two seperate devices.
  4. Play any audio source including playing a clip from youtube. 
  5. Go back to the the "audio MIDI setup" application and click the mute checkbox next to the slider on the input pane. 
  6. At this point the output will be muted; what should happen (desired behavior) is the input should be muted but it should not impact the output. What is happening is it is not impacting the input but muting the output

Since we are a new company we know that might be a little harder to accept that the issue was caused by Apple. That is why we outlined the steps above so anyone can reproduce this bug. We are exploring options to see if we can fix on our end but this is a complicated issue and Apple does not give control over the OS to anyone. 

Solution:

There is no real resolution for this issue at this time. We recommend not upgrading to macOS Monterey for the time being as this issue and many others are being addressed. 

We have contacted Apple to let them know of the issue and are trying to find a way to elevate this issue to the macOS dev team. 


Temporary Solution(s)

Option 1

If you use one of the conferencing applications for which we have level two or level three sync, you could disable our ability to control your microphone by unchecking the box next to "control this microphone with MuteMe" and then relying on the application layer to sync and use MuteMe with your favorite conferencing applications. 

Option 2

You could use a different microphone including the built in microphone and have MuteMe control that microphone but not control the bluetooth headset. You would also want to change your input device in your conferencing application to that other microphone.
