VLC not able to stream AC3 5.1 in MI Tv after the android pie update

Dear Team,

Recently I am facing an issue. My MI tv got android pie update few days back. Previously, my VLC player was able to stream dolby digital (AC3) codec and I was able to get a true 5.1 surround audio streaming. But recently, after the android update, when I was playing the same file, it is streaming LPCM (2.1) instead of 5.1. I have Sony HT-RT3 home theatre system connected via HDMI ARC.

Please help me to solve this issue.

Thank you.
