# audio/quit
Close the shared audio device and free every cached WAV, voice, and push stream. The next `audio/*` call re-opens the device lazily.
## Syntax
[audio/quit]
## Examples
[audio/quit] # release device + caches before teardown or suspend
## Returns
nil. On a host without SDL audio (`retra`) the call is a no-op and still returns nil. Cached voice/stream ids become invalid; `audio/volume` settings survive.
