avin7000 Posted October 24, 2013 Share Posted October 24, 2013 I have Dell XPS L501x and running Mavericks on it. I used the same audio kexts which I had used in Mountain Lion seems they are not working. Then I googled up and found out that L501x uses Realtek ALC665. So where can I find working Mavericks kext for it ? Anyone here have them working ? Thank you ! Link to comment Share on other sites More sharing options...
sargedessy Posted October 24, 2013 Share Posted October 24, 2013 Bro, the kexts from ML works. You have to remove npci=0x3000 from the boot flags. Link to comment Share on other sites More sharing options...
avin7000 Posted October 24, 2013 Author Share Posted October 24, 2013 I removed npci from boot flag, still no audio. Earlier I was doing some trial and error and had installed VoodooHDA.kexts off the net. I removed it and then tried again. Still no luck Link to comment Share on other sites More sharing options...
avin7000 Posted October 24, 2013 Author Share Posted October 24, 2013 Installed kexts from http://www.insanelymac.com/forum/topic/273500-os-x-mountain-lion-install-guide-for-dell-xps-17-l702x-optimus/ now ear phones are working, but not built in speakers. I had missed installing IOAudio kext. Using Kext Wizard I repaired kexts, build cache etc, then I re-installed again. Now seems working [no HDMI audio though ] Link to comment Share on other sites More sharing options...
xplus93 Posted March 6, 2014 Share Posted March 6, 2014 Installed kexts from http://www.insanelymac.com/forum/topic/273500-os-x-mountain-lion-install-guide-for-dell-xps-17-l702x-optimus/ now ear phones are working, but not built in speakers.
