To test if you device is able to output audio at all, independently from Engine Core, try executing `speaker-test`. Also checkout out the `-D` argument to test specific devices. If you system doesn't provided `speaker-test` you have to install or use your preferred way of testing also audio.

3. Now run `speaker-test`. It that's working, you now know that your audio device is at least available from within Docker and you'll need to further check your Liquidsoap device configuration.

Assure you have set the correct device ID. To do so check the aformentioned question. Check the audio interface configuration section in `engine-core.ini`. Verify if the default settings `input_device_0` and `output_device_0` are valid device IDs.
