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;-)
This question was solved. View Solution.

Try the following
Download the IDT Audio installer on the link below and save it to your Downloads folder.
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, download and reinstall the Chipset driver on the following link.
When the reinstallation has completed, shut down the notebook by holding down the Shift key as you click Shutdown to temporarily prevent a hybrid boot. Then unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
