I can confirm that this issue is present in all of my Tapo camera devices including my D235 doorbell  (Haven't mounted this outside door yet) & C320WS.

Why would the audio from the camera go lower when using the talk feature? It makes no sense as its impossible to hear the individual at the door unless using tap to talk (which I don't want to do)

Also using the 2 way audio also decreases the volume of the audio which I connected to my NVR via RSTP. This is very unusual and tells me that there's a setting which cannot be configured by the end user running in the background affecting all streams.(Rendering my doorbell useless)

Please could there be a feature request for this odd default setting to be disabled via advanced options?

E.g. an

I have just sent the message:

for clarification: this is also affecting the audio streams using the camera account feature.

This issue is present on:

Tapo C220 (shown in video sent)

Tapo W320WS (i have 2 and both have this problem)

Tapo D235 Doorbell

I need to be able to turn off the noise reduction during voice call for these cams to be usable.
