Sorry, but none of those suggestions worked. I did find out some more specific information.
In the device manager, the USB-1F xHCI USB Host Controller is disabled and there is a message that reads: "This device is not working properly because Windows cannot load the drivers required for this device (Code 31)"
Any suggestions? Thanks.

@CoasterJim posted a resolution to your issue with your USB device. I am linking you the thread below.
USB-IF xHCI USB Host Controller
I do not know if this will fix your original issue as I am not sure if your USB 3.0 drivers could affect your audio drivers but there is a possibility.
Please re-post with the results please.

I did see those posts and did try it. In the end, I was unable to download the Intel wireless display software getting a message that the platform was not compatable with Intel WiDi and my graphics driver could not find or load necessary components for Intel(R) WiDi!
At this point, I am totally out of my element and I will take it to a computer store for repair, as I have tried to troubleshoot it myself for a week now.
Thanks to everyone who offered help and tips.

If you haven't already taken the machine to a repair shop, it may be worth trying the following.
First of all, download the following Two files and save them both to your Downloads folder.
Next, open windows Control Panel, open Programs and Features, right click the entry for Intel WIDI and select Uninstall.
When this uninstallation has finished, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When this has completed, download and reinstall the Chipset driver on the following link.
When complete, shut down the notebook and unplug the AC Adapter. Hold down both the Power button and the Beats button for 10 seconds. Plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
Regarding the error you have with 'USB-IF xHCI USB Host Controller', do the following.
As you have switchable graphics, first make sure you switch to the Intel GPU.
Then, open your Downloads folder, right click on the Intel WIDI installer and select 'Run as Administrator' to start the installation.
When the installation has completed, check in Device Manager to see if the error has gone.
