Hi there, I hope you are all doing great.

I am currently using Pexip SDK in my android application, and I have a specific request that I cannot implement right now.

I want the call audio to come from an other source instead of microphone. For example, in the call, I want to be able to feed my own custom audio data (maybe a music from a file, or audio data coming from an other app or service), instead of getting it from the microphone.

Right now, I do not see a way to do that with the latest Pexip SDK version.

I explored the AudioSource from WebRtcLocalAudioTrack class, but could not find a lead.

Anyone here already done that and can point me to the right direction? or anyone knows if it is even supported right now?
