jsl2000 Posted October 15, 2012 Share Posted October 15, 2012 I have patched my original DSDT.aml to activate its HDMI audio working from both HD4000 and GTX-680. The only impecfectness is unable to wakeup after sleep. Can anyone help me for such a patching ? DSDT.aml.zip Quote Link to comment Share on other sites More sharing options...
