Audio Playback Issues on Samsung TVs (2020–2022 Models)

Smart TV
1

We are playing HLS video contents, video and audio both working fine on 2018 & 2023 model Samsung TV. On 2020, 2021 and 2022 model Samsung TVs, video is playing but audio is NOT working. Not able to see any error in console related to the player or audio.

  1. Are these codecs supported?
  2. Is the config correct? Or do we need to add or remove something?
  3. Any other recommended solution.

Please help.
