we tested MAC, Android and Windows7, all with video but no sound.

The verified chrome version is as follows

chrome: 66.0.3359.181 (64 )win7
chrome: 65.0.3325.109 (android7.1.1;OPPO R11 Build/NMF26X  )

   '[{"op":"add","path":"/info/inViews","value":"common"}]' 

   response :audio codec: opus, video codec: vp8

2.Try to modify extras/basic_example/public/scripts/index.js
  set subscribe  audio codec to aac, 

   then refresh Browser re-enter the room, but still no sound!   audio codec is opus.

    deom code below

            for (const stream of streams) {
                    if(!subscribeForward){
                      if (stream.source.audio === 'mixed' || stream.source.video ===
                        'mixed') {
                        console.log("subscribeforward mixed debug");
                        conference.subscribe(stream, {
                            audio: {codec:'aac'},
                            video: true
                        }).then((subscription) => {
                            subscriptionForMixedStream = subscription;
                            $('.remote video').get(0).srcObject = stream.mediaStream;
                            subscription.addEventListener('error', (err) => {
                                console.log('Subscription error: ' + err.error.message);
                            })
                        });

 

3. The Server-side MCU related information

     OS:CentOS Linux release 7.2.1511 (Core)

     MCU: CS_WebRTC_Conference_Server_MCU.v4.0.tgz

Hi, aac codec currently is not supported in webrtc transportation, it can be used in scenarios other than webrtc transportation like rtmp and recording. Please use other audio codec (opus, pcmu,  .etc) for webrtc transportation.
