Did you upgrade your chime to a 24v or the transformer to 24v? Do you have a link to the one you purchased?
Hikvision doorbell cam causing chime to buzz

I upgraded the transformer only to 24v... my chime is still 16v, and is running beautifully. I bought the transformer from Amazon https://www.amazon.com/gp/product/B000K2EC7K/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I opted to go with the more expensive brand name (Honeywell) than the other off brands...after going thru multiple transformers and chimes, I figured go with a name that I trust... (Honeywell thermostats here too as well.)

Same experience here. I had been struggling with finding a way to suppress the buzzing noise. I added the resistor that came with the Hikvision doorbell and it did kill the buzzing. However, most of the time when someone rang my doorbell, the chime would not ring or only ring very softly with a "ding", but never the "ding" followed by "dong". Very frustrating. I removed the resistor and used the 24VAC taps on this transformer Hampton Bay Wired Door Bell Tri-Volt Transformer Compatible with All Video Door Bells-HB-125-03 - The Home Depot.
Earlier comments on this thread from @skylab001 and @tangent were right on the money to understand what is going on and why the 24V transform helps. Electrical power is Volts * Amps. By bumping the voltage up from 16 to 24, the amps drawn by the Hikvision doorbell drop proportionally. The solenoid in the chime is fundamentally a electromagnet driven by current. So voltage up, current down, and less vibration of the solenoid plunger which means less noise.
In my case, there is still a very slight humming of the chime after changing to 24V. By tweaking the two screws holding the chime to the wall to minimize the very slight buzzing sound to the drywall, the only hum I can hear is if I have my ear almost touching the mechanical chime. And, almost as important, the doorbell chime now rings "ding" "dong" everytime the doorbell button is pushed.

With the 24v transformer I can verify that the constant buzzing is gone. I used the same Hampton bay trafo as Priority because my local store had it. There is a mild 60 cycle hum which you can only hear if you put your ear within a foot or two of the chime, most probably won’t even notice it, but since I was listening intently for any buzz I of course heard it...
Best of all the chime both dings and dongs like it used to. After adding the hik doorbell we rarely got the second bit of the bell. Win win. Maybe they should just recommend anyone with a mechanical chime should use a 24v transformer.

Couldn't agree with you more. Swapping a transformer to address 99% of the noise is something any handy person can do.
Had I not had success with the 24v transformer, the next step I was exploring was implementing a current sensor on the doorbell wires to detect when someone pushed the doorbell switch (differentiate between (1) "normal" current to the doorbell and (2) an increase in current when the doorbell switch is pushed/closed) and pulse a relay to activate the mechanical chime (inspired by this Doorbell Detector). As much fun as this project would have been, the complexity is clearly beyond swapping one readily available component!
had to chime in on this one.. i keep seeing this should work or this or that might work..
im the CCTV manager for VORTEX SECURITY in florida.
we install this doorbell and lots of hikvision products.. this doorbell many many times in different situations..
if your mechanical OR digital chime is between 16-24v and is buzzing.. install the resistor per the directions.. works every time.
if using a stand alone power adapter (we like using the 16.5v alarm panel adapters because they screw to the outlet) , use the provided fuse
make sure the app settings are set for your chime type
if doorbell is on same LAN as an NVR add it as an ip camera on a channel of the recorder (note: user is admin and pw is the verification code on doorbell) the recorder will locate it automatically in the un added ip cams list but its easier just to manually add it to whatever channel you want...
to use constant 24hr recording thru nvr or tribrid dvr with whatever size harddrive you use. memory card only records event and motion. with 128gb max. only saves for a few days or so. depends how many events.. two way call button feature needs doorbell to be added to hik-connect seperatley also.. we like doing both ways at same time.

Installing the resistor is a cure that is almost as bad as the problem IMHO. With the resistor installed, the doorbell will NOT reliably ring. In this config, at best, a mechanical chime will only "ding" and not "ding-dong". At worst, a visitor will press your doorbell button and your chime will not ring all depending on the length of the button press is too short.
The newer hikvision doorbells include a "power adapter" that does NOT have this issue.
