Hi Envy-us,
Thank you for responding back with all the information!
With loosing all audio, and the Beats audio software, there will be a couple different steps that you will need to go through. I would suggest the following document 'No Sound from the Speakers (Windows 7)'. Since you have lost all audio, I would start off with document first.
Now with completely losing the Beats Audio software from your computer, one options of possibly getting the software back onto your computer, is to reinstall it from the Recovery Manager. I have included the document 'Using Recovery Manager to Restore Software and Drivers (Windows 7)'. I would suggest clicking on the option for Software Program Reinstallation, and follow the steps for reinstalling the software.
Please let me know the outcome of the above troubleshooting steps.
Good Luck! :)
