macOS Monterey 12.0.1 - FaceTime fails upon answer.

After upgrading my 2020 iMac 27" to macOS Monterey (12.0.1), whenever I make or receive a FaceTime call, a "call failed" message appears and hangs up as soon as one participant answers the call.


I reinstalled macOS Monterey but this did not fix the issue.


Has anyone else experienced this and if so were you able to resolve the issue.

iMac 27″, macOS 12.0

Upon further investigation, it appears that the FaceTime call failure is caused when one uses the iMac speakers as the output device.


Tests using the output device selection of external headphone jack or a bluetooth device does not replicate the call failure.


Hope this helps until Apple addresses a fix in a future update for use case scenario of the

FaceTime Call failure on 2020 iMac 27" to macOS Monterey (12.0.1) when the

selected output device is the internal iMac speakers.


The iMac mic does NOT come into play as the call is successful when the input device selection is either

an external USB mic,

a bluetooth device or

the internal iMac mic


combined with an output device selection of

the external headphone jack or

a bluetooth device.

Actually, it didn't on my MBP -- everything continued to work swimmingly well for me, even with 12.01. However, with the 12.1 "update," using my display as the sound input device simply ceased working altogether (even tho I've selected it as such in Settings). Thankfully, it works nicely with my AirPods, but I got spoiled by using the Thunderbolt Display as my audio input without any other connected devices and not having to worry about charge levels on my AirPods. What's a bit of a head scratcher is that after 12.1, using the TBD as the handsfree output device continues to work. However, no joy using the TBD as the sound input device for FaceTime (again, even tho until the upgrade it had worked flawlessly for a long time).
