As explained in the changelog, that should not be needed anymore with the release of v310 or later.
Xiaomi Redmi 8. Media is working fine, wired headphones are working. Everything works fine instead of Bluetooth headphones. Didn't try the treble app though, I'll use it and see if it works
By media, I mean media through bluetooth.
Nope. When I connect my headphones via Bluetooth, media plays through the phone speakers not through the headphones even if I set them as the output device
Did you try this?
Safety Net is passing in my builds as you can see from my screenshot attached.
Always use stock boot as my old phone doesn't has any custom boot available. The problem emerged from the very first time it finish flashed (no mod, no hack). I always check the mobile bank app first as it's critical use for me.
