Transcoding a channel it gets muted audio

I’m having a problem in transcoder
When transcoding a channel it gets muted audio
it appears the audio more mute I can put the pids that this already tried to put the option ab = copy and does not change anything that can be and what can we do to solve?

Hi, This i depend of what codec coming from the source and what codec are you use as output codec. For example, mp2a is not compatible with the browser and some transport proto (such as RTMP, webrtc). AC-3, OPUS has the same limitation with container and transport protocols. So there is a lot of possible variants why you hear a slice after transcoder. You can contact support to show metadata of your source and what transcoder option you use. And after that can suggest adjusted options for avoid this behave
