Problems with sound in libreelec 9.0.2 with Odroid-C2

  • Hello good morning everyone, I have the libreelec 8.2.5 (Kripton 17.6) system installed on my Odroid C2 and the sound is as hdmi 5.1 and all the series work perfectly whether they are 5.1 or if they are 2.0, I have formatted another sd with the 9.0.2 system (Leia) and when configuring the sound just like the previous system, I have verified that the series that are recorded with 2.0 are not heard, but those that are recorded 5.1 are perfectly heard. Is it a configuration problem? Or is it a programming problem.

    Can I do something about it?
