I used Dell Laptop, Windows 7 64 bit every day.
I am 83 and like a bigger screen with better color.
My normal hookup is HDMI out from my laptop and in to 19" Vizio
I never got audio through HDMI out.
I used headphones, stereo from the #1 stereo jack, audio OK
For 3 or 4 months I bought Sonawave USB Stereo clip on speaker, great.
When I get up early AM, between 4 and 5, I switch to headphone not to disturb wife
Yesterday I could not hear any audio from headphones.
I do get audio for USB
Corrective action tried and failed
Verified default setting via Control Panel and test
Audio displayed but not heard on headphone
Audio displayed and heard on the USB Sonawave
Today I used Norton 360 to check register.
It cleaned some problems but still no headphone sound
I plugged same headset into my Vizio HDTV and sound is working
Any suggestions, I am more of a user than a tech.
