Give an example of application and exact song list, I'll try to repeat your trouble.Hey Guys,
i have the same Problem with the Sound (only Music, Youtube, etc), like the one Guy with his Bluetoothspeakers (i think he posted in february, but dont get a solution).
Following Software is in action:
Lineageos 17.1 from 20.06
Firmware Version 11.0.8
First i had installed a older Lineageos 17.1. I think 03.06(?). With that i had the problem that every Music Player, or Youtube, or Spotify had that problem, that one Song is loud and clear, next no sound, next loud and clear, next no sound. Every secound time. Youtube the same.
So i googled last weeks for this problem, but didnt find a solution. Until i found this thread.
So, i wiped the whole Smartphone. Data, Cache, everything.
-flashed the latest Firmware fw_beryllium_miui_POCOF1Global_V184.108.40.206.QEJMIXM_146861c001_10.0
-flashed the newest recovery from Lineageos from 20.6
-flashed the newest Lineageos 17.1 image from 20.6
-flashed the newest Magisk zip
Its working everything. Execpt the Sound. Now i have not the exact same problem. Because now i have following behavior: First song loud and clear, next song very silent (but with super good ears hearable), next song loud and clear, next song very silent, and so long.
2 hours of listening to spotify and NewPipe through Bluetooth with Radsone EarStudio without any issues, super clean and powerful sound.
Have you checked Bluetooth settings on Programmers settings section?
