Audacity uses PortAudio as its audio API, you may wish to set the USE flags for media-libs/portaudio to add or remove support for an audio backend from Audacity.

Troubleshooting

JACK missing as a host

If the USE flag jack is enabled for media-libs/portaudio, and JACK still isn't available; it's likely because JACK isn't running. See the article JACK on help setting it up.

If using Pipewire, you can use it as a JACK replacement by enabling the USE flag jack-sdk for media-libs/portaudio.
