[FFmpeg-user] Audio captured via AVFoundation is unusable

I haven't seen another reply to your request, so I'm offering this one.

You may want to try the HEAD version of ffmpeg. Sometimes the HEAD version provides a remedy for some issues, but not always.
If it doesn't provide a solution, you can remove it, and reinstall the release version as you did before.

To install the HEAD version, first uninstall (remove) the version you've already installed (but please read the rest of this message before you begin):

"brew remove ffmpeg"

If you have ffmpeg dependencies installed, you may have to forcefully uninstall ffmpeg using: 

"brew uninstall --ignore-dependencies ffmpeg"

As an alternative to forcing uninstallation, you may note each package for which ffmpeg is a dependency, then uninstall each of those, then uninstall ffmpeg as stated above. If any other packages have as dependencies the packages for which ffmpeg is a dependency, you have the same choice about either forcing their uninstallation or first uninstalling packages that have as dependencies any of the packages for which ffmpeg is a dependency.

After ffmpeg has been uninstalled, you may then install the HEAD version of ffmpeg with:
"brew install homebrew-ffmpeg/ffmpeg/ffmpeg --HEAD --with-two-lame --with-xvid --with-fdk-aac --with-libbluray --with-libsoxr"

The  above installation command includes options for installation, which you may or may not need. Not all listed options are compatible with the Mac version, so if you can't install with a given option, omit that option and try again.

You may upgrade the HEAD version without specifying the options specified when it was installed:
"brew upgrade homebrew-ffmpeg/ffmpeg/ffmpeg --fetch-HEAD"

When using the HEAD version of ffmpeg, "brew doctor" will list a caveat related to the name "ffmpeg". AFAIK, you have to remove the HEAD version of ffmpeg in order to stop receiving that warning when you run "brew doctor".

Good luck!
