javascript - Twilio Video. I can display video without sound -


i testing twillio functionality. backend(sending tokens, access rights) works fine. in frontend part video remote participant without sound. can see eachother. can't hear him , can't hear me. how repair it? have sound , have option mute/unmute sound microphone remote participant can't hear me. if have other suggestions code please let me know.

this part of html:

     <div class="container" id="conversation">             <div>                 <video id="localvideo" ></video>                 <video id="patientvideo"></video>                 <div class="buttons">                     <span>                         <a href="{% url  'calendar' %}?day={{ request.get.day }}">                             <img class="btn" id="call" src="{% static 'images/conversation/finish-phone-call.png' %}"                                  alt="call"/></a>                     </span>                     <span>                         <img class="btn" id="mute" src="{% static 'images/conversation/icon-microphone-mute-01.png' %}"                              alt="mute"/>                         <img class="btn" id="unmute" src="{% static 'images/conversation/icon-microphone-unmute-01.png' %}"                              alt="mute"/>                     </span>                 </div>              </div>

this part of javascript. works. can connect room , can share videos between participants.:

var local_participant; var videoroom;  $("#call").click(function () {     sendnotification("call canceled");     if(videoroom) {         videoroom.disconnect();     } });  $("#mute").click(function () {     $(this).hide("fast", function () {         $("#unmute").show();         local_participant.audiotracks.foreach(function (audiotrack) {             audiotrack.enable();         });     }); });  $("#unmute").click(function () {     $(this).hide(function () {         $("#mute").show();     });     local_participant.audiotracks.foreach(function (audiotrack) {         audiotrack.disable();     }); });  twilio.video.connect(doctor_token, {name: room_name}).then(function (room) {      videoroom = room;      twilio.video.createlocalvideotrack({audio: true}).then(function (localtrack) {         localtrack.attach("#localvideo");         room.localparticipant.addtrack(localtrack);         local_participant = room.localparticipant;     });      room.on('participantconnected', function (participant) {         console.log('participant connected: ' + participant.identity);     });      room.on('participantdisconnected', function (participant) {         console.log('participant disconnected: ' + participant.identity);     });      room.on('trackadded', function (track, participant) {         console.log(participant.identity + " added track: " + track.kind);         track.attach("#patientvideo");     });      room.on('trackremoved', function (track, participant) {         console.log(participant.identity + " removed track: " + track.kind);         track.detach("#patientvideo");     }); });

twilio developer evangelist here.

in code local user's video track calling:

twilio.video.createlocalvideotrack({audio: true})

however createlocalvideotrack not create audio tracks. instead, should call createlocaltracks:

twilio.video.createlocaltracks()

the default options createlocaltracks { video: true, audio: true } should need. promise resolves array of localtracks need update callback code too.

twilio.video.createlocaltracks().then(function (localtracks) {   localtracks.foreach(function(localtrack) {     localtrack.attach("#localvideo");     room.localparticipant.addtrack(localtrack);   })   local_participant = room.localparticipant; });

let me know if helps!
