Sound quality speakers issue on Veux

[Davichi]

Redmi Note 11 Pro 5G

I recently updated from EEA to Xiaomi.eu and I noticed that sound quality got worse and quieter too

When I listen to only left and right channel it seems the right (bottom) speaker sounds awful and quiet and the left (top) seems okay.

I'm wondering is it bug or something else?

I have the same the Device but it's working fine.
The speaker sounds are okay, but not so great compared to other model's. Did you reflashed the ROM ?
