When I plugged my HDMI in no sound came out the tv, so when i checked device manager intel audio chipset had a yellow triangle next to it, I found out online that my intel graphics HD 4600 driver needs upgrading as the latest version is 15.33.14.64.3412 but hp envy 1 j130ea keeps blocking the instillation saying its not validated for this computer. Are there any suggestions as the newest driver isnt available on the HP website
