@marcolamia this"when I recharge my cell phone the problem spreads to all sounds" makes me think that it is a parts issue. Double check your work and consider replacing the parts once more. Let us know exactly which parts you replaced. That can give us a better clue on what is going on with your phone.

@marcolamia I see. that makes sense and yes, if you do not have the tools it's difficult to get into a board repair. You have rebooted your phone and maybe you should consider a complete restore of your software.

Here is what you need to look for in regards to schematics for your audio circuit [document|35271] and you will need this [document|35270] to find the components on the board. I know you do not have all the tools yet, but since it could be the circuitry that gives you issues, you will at least have to start looking at it. It's not like we can say "the bad component is R2415 etc." Those are things that have to be determined by troubleshooting of the circuitry. It's not easy and can be very tedious but with determination it can be learned and can be done.

@marcolamia let us know if the ringtone that cause this are custom ringtones or the Xiaomi default ringtones. I am still leaning toward this being a software issue. Check {https://xiaomi.eu/community/threads/ringtone-notifications-error.52170/#google_vignette |on here]
