Dear All

I have some problem on Sound issue. When I install IDT high deffinition driver from HP website the sound driver will disappear n need to reinstall. I uninstall it and it become High Definition audio driver, and got sound now, however, the sound will mute on on and click button will turn sound touch button at top of keypad to mute and on. When i play movie or movie, the sound will on. only it will mute n on by itself.... not nice and very troublesome. on n off listen "tick" "tick". Anyway to solve it.
