Theme development

The Favicon on my site, HousePouch.com, is pointing to an old domain, dev.housepouch.com, which does not exist anymore. I cannot seem to change the shortcut link in the header of the site... I have tried multiple methods of fixing this:

- Adding preprocess code to the template.php and creating a custom module
- Changing the options in the theme settings page

I am trying to access the uri of an mp3 with the field name field_audio_file so as to embed it in a source tag for an audio tag.
I have used kint to find what array the uri exists in which I think is content._field_layout.content.field_audio_file in #file.uri though I am not sure how to access arrays with a #.
Can anyone give me any suggestions?
