Hello, the firmware you are using is the latest
Edge2 Android 12 V230114

If that firmware was updated on 14 January 2023, no. Can I update the firmware without reinstalling Android?

@Sinky

Hello, you mean that if you use Edge2 Android 12 V230114 firmware, there will be no HDMI sound phenomenon?

Thank you. I updated the firmware and now I have sound.

This worked for a bit and now no sound again!
