Internal Speakers not listed
I turned on my computer this morning and my volume all of a sudden wasn't working. I tried to reset my computer multiple times and have done research and found nothing to help. I went into my settings and sound and nothing was listed under output or input. Nothing is jammed in my headphone jack and I don't know what to do. The internal speakers isn't listed under output and I can't click on anything within the sound settings. Also, I try to turn down or up the volume and it shows a circle with a slash through it. Please help. Thanks.
