I’ve been using VoodooHDA.kext for my HP-X360 i7-4510u, HD4400 Realtek\u00a00x10ec0282, but it doesn’t\u00a0auto detect when I have to plugin the headphone\u00a0<\/em>which is inconvenient sometimes. I found the patched on InsanelyMac.com kext<\/a> that works well, but I still have to patch the DSDT to get it working. The result is only has 2 ports, input and output, NO mic or speaker external options, when you plugin, it will change accordingly (NO HDMI).<\/i><\/p>\n

\"AppleHDA\"<\/a><\/p>\n

–\u00a0Copy the original AppleHDA.kext somewhere in case you need to use it, always.<\/i><\/p>\n

–\u00a0Install AppleHDA.kext from\u00a0the download using Kexthelper or\u00a0<\/em>Kext wizard.<\/i><\/p>\n

– Add the patch fix_irq from Rehabman and\u00a0hdef patch to id layout 12 to 3.<\/i><\/p>\n

\"IRQ_fix<\/a><\/p>\n

To get the HDMI to work, patched AppleHDA.kext must work then edit the Clover config.plist to add<\/em><\/p>\n
