1.pngDo not webrtc support speakers? Even when muted is turned off, the volume is blurred.
Hello @HOU O YOUNG, we do support full audio capability in WebRTC (for Google Chrome and Mozilla Firefox). Are you using WebRTC in and WebRTC out for playback? If you are, we recommend that you use VP8 video with either Opus or Vorbis audio for the best performance, but H.264 is the most broadly supported WebRTC codec.
If you are transcoding your WebRTC to other formats for playback, then we recommend transcoding your stream into any standard output, such as AAC audio and H.264 video, and deliver the transcoded rendition to your viewers. This reduces the bandwidth required to sustain the connections and video quality.
Again, not all browsers fully support WebRTC and so that could be affecting it. What browser are you using?
- Audio quality may vary
The differences in the way audio has been implemented in browsers are known to affect audio quality. This is a limitation of WebRTC, and can’t be fixed by Wowza Streaming Engine.
With Wowza Streaming Engine, you can ingest and play WebRTC streams with Mozilla Firefox and Google Chrome browsers on desktops. At this time, we don’t support ingest or playback of WebRTC streams on mobile platforms or in a live repeater (origin/edge) configuration.

If you are still having issues, you can have engineers look at it and test the audio here for you. We could do that for you through a support ticket.
“. At this time, we don’t support ingest or playback of WebRTC streams on mobile platforms or in a live repeater (origin/edge) configuration”
WebRTC stream from browser to Wowza, I can play HLS url on mobile, but the audio is nothing.
Audio Icon show normally when I open the URL on Safari of MAC, but can not hear the sound.
Do you know why @Rose Power-Wowza Community Manager?

Do you know why?
I’m happy to try and help @Duan Nguyen. Glad to hear you have it working, but since all browsers don’t fully support WebRTC and there can be issues, we don’t officially support it just yet in mobile platforms, but it’s not impossible. We are aware there is limited support on Safari.
But, we do have some tips to share with you if you would like to continue experimenting:

AAC audio not supported with WebRTC
Google Chrome and Mozilla Firefox don’t support AAC audio over WebRTC. WebRTC streams with AAC audio are played as video-only. -
When publishing WebRTC streams, it’s important to note that browser support for codecs varies. We recommend that you use VP8 video with either Opus or Vorbis audio for the best performance, but H.264 is the most broadly supported WebRTC codec.
-
We recommend that you use the Transcoder feature in Wowza Streaming Engine to transcode the WebRTC stream into any standard output format, such as AAC audio with H.264 video. Then you can deliver the stream over Apple HLS, Adobe HDS, or MPEG-DASH, which enables you to scale your WebRTC solution without the significant bandwidth that would otherwise be required to deliver your streams to viewers with satisfactory quality.
