Hello
I have a HP ENVY 15-j035eo Notebook PC and suddenly all sound disapered.
I have upgraded from windows 8 to 8.1 the sound worked for a 1-2 weeks
.
The text when I click on the speakers says (translated from Swedish;-))
" Sound improvements for the following units are causing problems: speakers/headphones ( IDT High definition audio codec)."
Anything to do but rebooting to W8 and start over? BTW I hate W8;-)
