New Redmi K20 Pro [10.3.15] Camera video recording no sound

[ailionx]

I just recently installed 10.3.15 on my Redmi K20 Pro and found that the video recording doesn't have any sound. I can confirm that when playing other videos, the sound is working but when playing newly recorded video, there is no sound. Tried to reboot but that issue still exists.

@ingbrzy any idea why this is happening. Is it a bug or due to any mistakes in flashing process?

Following up. It's more like this issue: https://xiaomi.eu/community/threads...e-assistant-and-apps-incompatibilities.51557/
I feel it's got the issue after it's disconnected from the bluetooth device in my car which was the audio output. I just shut the power of the car down and the bluetooth was forced to be disconnected. Then it got the issue. No sound, no mic input. But I tried to recover it by conncting it to my bluetooth earbuds, tried some video and then disconnect the bluetooth device. The speaker and the mic started to work again.
