HP Pavilion dv6 Notebook PC Windows 7
Had been using an external speaker by plugging it into headphones jack of laptop. Starting couple months ago, after using that speaker, I would need to restart the PC in order for the internal speakers to work. Now, I get no sound at all from internal speakers but headphones work perfectly. I have already gone through the troubleshooting steps found at http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c01912228. Everything shows to be working properly. Still, I get no sound from the internal speakers.
