Troubleshooting

JACK missing as a host

If the jack USE flag is enabled for media-libs/portaudio, and JACK still isn't available, it's likely because JACK isn't running. PipeWire-based systems can use PipeWire as a JACK replacement by enabling the jack-sdk USE flag on media-libs/portaudio; otherwise, refer to the JACK article for information on setting up JACK.

No audio output on OpenRC+PipeWire

Absence of audio output on a OpenRC+PipeWire system might indicate that the elogind USE flag needs to be enabled on the media-video/pipewire package.
