Jio STB surround sound issue

[Ninja619]

I have issue about Surround Sound from Jio STB. I have Jio STB 2022 model. Its connected to Sony 32 inch LCD TV (12 years old).
The issue is, when I am watching any TV show on Zee5 or SonyLiv, dialogue Audio level is very low, while background music is very high. If I increase TV audio level to listen dialogues clearly, Background music audio level also increases even more. It gives headache if I watch any show for more than 60 min
This issue is not seen while watching Live channels from JioTV+.

I have Airtel Xstream STB connected to same TV. Such Audio issue is not seen with Airtel STB and for same TV shows/OTT apps, Audio of dialogues and Background music is at same level.

I tried PCM/SPDIF/Auto Audio settings, but no change. So what setting should be changed to get rid of this issue?
I don't have compatible Audio System or Sound bar to route Audio through that.

Same issue I am facing have you found solution
