I am at a loss. The sound on my laptop (o/s Windows 10) stopped working seemingly out of nowhere. I was watching a movie using VLC and it was fine, left my computer for about 30 mins and came back. The computer did not go into sleep mode or anything at the time. I initially tried to open Netflix though every movie I tried to open was running at an extremely slow frame rate with no sound. I gave up, assuming it was the internet being slow and tried to resume the movie although there was no sound. I tried with and without headphones with no success. I opened YouTube and which was buffering very slow and then wouldn't play. My internet speed was fine.
I tried to update the sound drivers (Conexant High Definition SmartAudio 221 and Windows High Definition Audio Device). I have disabled and re-enabled. I have run virus scans and did general cleaning, restarted the computer multiple times. The troubleshooter doesn't see any problem and the audio device looks as though it is working properly. I don't think it's attributed to upgrading to Windows 10 as I did that almost a year ago. Please help!!!
