macOS 12.6.9, 12.7 and 13.5 audio stability?

Dear users,

In September this year, I often experienced that MacOS 12.6.9 lost all audio devices. That is, MacOS did not find any sound devices in the system preferences and also in the volume control. The only solution was a reboot.
After updating to 12.7, this phenomenon is resolved, but often all software that uses audio devices freezes. The only solution is to restart the operating system.
It is unstable and I cannot concentrate on my work.

What about the stability of MacOS 13.5?

What Mac do you have? Do you have any third-party audio drivers or audio hardware?

I doubt this is a universal problem of everyone.

My main computer is a MacBook Pro 2021 (M1 max). I mostly use the Macbook speakers and external headphones on this computer, and occasionally the MOTU UltraLite. I attach an image file showing all my audio devices.

The LG TV SSCR and MOTU UltraLite are connected to a CalDigit Thunderbolt 3 dock which has CalDigit Thunderbolt audio input and output devices.

It was stable before, but I have had this problem since September this year.

You need to check whether each of those has drivers installed; and whether they are up to date; and see whether the problem goes away if you remove those devices.

It might not be universal, but the 12.6.9 debacle also hit me. Maybe there is a reason why it lasted just ten days, before a new release was issued.

All drivers are up-to-date. I am thinking to upgrade my main machine to macOS 13.5 when it is more stable than 12.7…

I am now using MacOS 13.6.3 and this happens again and again. I seem to have found a solution by running the following command in a terminal window:

sudo killall coreaudiod

Have you tested removing each one of your audio devices in turn?

Yes, of course.

Any reason you’re not upgrading to 14.2…?

It is not necessary to force-quit CoreAudio daemon. You can open Activity Monitor, find coreaudiod, Quit it normally, and the System immediately relaunches it. (Maybe there’s no practical difference, but quitting from Activity Monitor seems gentler to me.)
