When playing:

        function playTone() {
            window.audioCtx = new AudioContext();

            // Create oscillator
            const osc = window.audioCtx.createOscillator();
            osc.type = 'sine';
            osc.frequency.value = 440; // A4 note

            // Create destination stream node
            const dest = window.audioCtx.createMediaStreamDestination();
            osc.connect(dest);

            // Hook up to audio element
            const audioElem = document.getElementById('audio_source');
            audioElem.srcObject = dest.stream;

            var selected = document.querySelector('input[name="sink"]:checked');
            setSink(audioElem, selected.value);

            // Start and stop beep
            osc.start();
            audioElem.play();

            setTimeout(() => osc.stop(), 1000); // 1 sec beep
        }

We hear garbage.
