Audio(sound) is missing in licode recorded *.mkv files


I am using licode docker latest image on my machine to run and test licode video recording feature. The recording feature is working as expected only audio is missing in recorded *.mkv file. I have already cross checked the configuration part. Audio in config is true while making the connection with erizo. localStream.hasAudio() return the true. So i have no idea what i am missing here.


I have the same issue with mediaConfiguration = 'VP8_AND_OPUS'. Here is the media info of the recorded mkv file:

Video: VP80 640x480 50fps [V: vp8, yuv420p, 640x480]
Audio: Opus 48000Hz stereo 3072kbps [A: opus, 48000 Hz, stereo]
