Please re-enable the legacy audio subsystem option

Some early 2020 update seems to have silently removed the 'advanced audio' option of using the legacy audio subsystem.

Sadly, the new audio subsystem is completely unusable for voice chat for a number of users. On my Mac with a Universal Audio interface and a Shure SM7B, it completely chops and garbles my voice. No other voice chat app (e.g. Skype, Hangouts, Zoom) has any of these issues.

Can we please re-enable the legacy system given that it worked fine?

Thanks!
