kazam changes the recording level without warning

[Eduardo]

Ubuntu 16.04.3 LTS
4.13.0-32-generic
Kazam - "NCC-80102" 1.4.5

Steps to reproduce the bug:

1. Click on the speaker icon in panel and then on Sound Settings

2. Click on INPUT tab, then under "Chose a device for sound input" click on "Monitor of Built-in Audio Analog Stereo" or a similar name meaning recording level for internal sound like those that will go to the speakers or earphone.

3. Move the slider to adjust the recording volume to your needs.

4. Start Kazam and be sure to have "Sound from speakers" marked.

5. Choose "Preferences" in menu "file" in kazan

Then look how the recording volume you had set up in Sound Preferences changes unexpectedly to a low value.
