Automatically reduce front audio in

When i talk to someone via mnjaro pc…the input audio sound reduce automatically…if i configure again… it will go previous State again.

Welcome to Manjaro forum

If this issue occurs when using Voice over IP software (Discord, Skype, Zoom etc) they usually have an option: Automatically adjust microphone settings or Automatic Gain Control
turned on by default. Any setting like this for audio processing should be turned off to keep the microphone level fixed to optimal level
