Hi, I have the updated windows 8.1 hp laptop. I've updated it about 3 weeks ago and never had a problem, till now. I was watching youtube videos and my sound was working, then I received a skype call, I paused my video and then I answer the call. Everything froze up for a minute, then everything went back to normal; but my sound completely went out. I have been to a lot of site's to try and fixed this problem. I have done update checks, update driver checks, audio toubleshooter, sound card check, I've restarted my computer, shut down my computer, went into my audio setting, that I have never touched till now, and nothing's working. I have tried just about everything and I'm becoming more frustrated with every attempt that winds up failing. I know it's not the last update I did for the 8.1 because I did that 3 weeks ago and everything has worked, up until this point; and I've checked about my mute setting and nothings muted. I need help to figure this out cause everything I have looked up has not been working.
