Issues with applications changing audio volume

I have been having issues with setting a sound level, or microphone level in the audio manager in Plasma, and then that setting changing when using an application. For example I listening to music on firefox I can set the sound level to about 20%, and then when the song changes it resets the sound level to 43%. I have also had issues with Zoom where I set the microphone volume in zoom to 100% and then when I start speaking it reduces my microphone volume to 20%. Is there a way to lock these settings or a workaround that would not allow programs to set their volume level after I change it? Thanks
