The audio is not played because the first PMT table does not contain any audio track. I don't know if it is allowed though.

I'll assign to @AquilesCanta who probably knows the answer.

[AquilesCanta]

As @kimvde points out, the media is malformed. I will check whether MediaPlayer successfully plays the audio and I'll add a workaround for this if MediaPlayer effectively plays the media.

[AquilesCanta]

I can confirm the media plays with audio on MediaPlayer. I'll add a workaround to fix this in ExoPlayer.

When will this be fixed?

[AquilesCanta]

Thanks for your patience. I cannot provide any timelines, as there are other high priority tasks that need attention. I'm sorry for the delay.
