I have a HP Pavilioon dv6 notebook pc and i've had for 1 year now. There has been no problem with anything until this morning when I found my internal mic wasn't working, i've tried restarting my computer and checking for updates and everything is up to date. i've already tried searching for a solution on google, but none of them have been working. I checked my sound and everything and it still wouldn't work. my webcam (built in) is working, and its just my microphone. my microphone is built in also. any help?
