Bug Audio Save System Bug

Short description
When saving the new audio settings and reopened, the new values are not reflected accordingly to the last saved in the UI Audio settings panel

Expected behaviour
Last saved settings should reflect in the Audio setting panel to change again from the last value.

To Reproduce
Steps to reproduce the behavior:

1. Open Audio Settings
2. Update values and save it and close the Audio UI
3. Reopen the Audio Settings, the new values saved last time doesnt reflect correctly.

Suggested Fix : By passing the correct audio setting values during setting up Audio UI settings
