Hi,
Every time I try to record through the microphone, Anki immediately crashes. But when I change the voice recording driver from Qt to PyAudio in the Preferences, it works like a charm. Problem is, when I changed the driver to PyAudio, it says that this driver will soon be deprecated… so I’d appreciate some help here.
The Anki version I have:
Version 2.1.49 (dc80804a)
Python 3.8.6 Qt 5.14.2 PyQt 5.14.2
Thanks
Please click on ‘report’ when it crashes, then copy and paste the first ~200 lines here.

What type/model of Mac are you using? Do you have any third-party tools installed that modify audio handling/routing?
Sorry for the late reply. I had Soundflower installed. I just uninstalled it, and now the Qt driver is working fine 
Thanks for your help!
