"Use browser microphone" not working

[FlorinAcsinte]

Hi. Just installed Rhasspy as a HomeAssistant addon.
Trying to use the browser microphone fails.

TranscribeSpeech.vue:264 Uncaught TypeError: Cannot read property 'getUserMedia' of undefined at u.getMicrophonePermission (TranscribeSpeech.vue:264) at n (vue.runtime.esm.js:2023) at HTMLInputElement.t._withTask.t._withTask (vue.runtime.esm.js:1822) getMicrophonePermission @ app.e552a466.js:1 n @ vue.runtime.esm.js:8 t._withTask.t._withTask @ vue.runtime.esm.js:8

From those 3 errors, 1st one comes up when selecting "Use browser microhpone", 2nd one comes up when holding the button, 3rd one when releasing it.

Tried using https and http, did not make a difference.
Weird thing is that the browser never asked me for microphone permissions, so it might be something related to that..

Tried this on chrome and firefox, on macos, and with firefox on ubuntu 19.10.
