My Model is HP Envy 14 inch, Windows 7 64 bit. Serial number: CNU125066Z. Physical look : black with red keyboard lighting. comes with beats audio. 2011 model.
Recently I connected it to watch movies online and found a great experience if connected to my plasma tv. Bigger picture.
However when I unplugged the HDMI from my laptop, I could no longer hear any sound from my own build in speakers if I play music or video. However , if i plugged in a headset it works. I can hear from my headphones.
I checked the sound settings its on Integrated speakers and device reported by system working properly. what has happened. Pls advise.
