I have a problem with some channels and I wanted to see if they could be fixed since it seems to be a problem of codecs, these channels are played well on "MX Player" but in the ProgTV I could not get audio but the video is fine, I leave you 3 channels of which these problems are presented:

In the MX Player I can see that the audio is in HEAAC, I hope you can play the links and be able to fix the problem
