I can't set up a microphone on my A515-54.

I am unable to configure either the microphone array or any external microphone to my Aspire A515-54. When I attempt to configure the mic, it takes me to the speech recognition control panel. When I attempt to set-up a mic there, I get a pop-up box stating "The Wizard could not start. Make sure your audio hardware is working properly and check your audio configuration in the Audio Devices and Sound Themes control panel." I do not have a "Audio Devices and Sound Themes" control panel. I have tried reinstalling the Realtek audio driver. I also checked the Realtek Audio Console to make sure the microphones were not set to mute.
Thanks!
