Worked Perfectly!!! Thank you

Should I use the Broadwell version instead as the 820 g2 has a Broadwell chip set? i5-5300

Ok so we determined its a ALC280. I downloaded the zip file from github and extracted it. I am guessing that I have to load AppleHDA Probook.kext into S/L/E with Kext wizzard. If you could break down the required steps to follow as I'm not sure what you mean. Even though this is my 4th...

same here

I have the same sound card in my Elitebook 820 G2. I got mine to work using VoodooHDA Package. It is not the correct driver and has some issues, but it makes the speakers work. keep us posted if you find the correct patch for this sound chip.

it has been disabled. still has same issue. Bluetooth works after sleep, DW1560 card

IOreg before sleep

Thank you for all your help The IOreg wass taken after i put it to sleep and then the bluetooth would wake up. When you boot into OS X, it shows "Bluetooth Unavailable" after waking up from sleep, bluetooth is on Here is the dump from Linux. Not sure if it is right

Hope I got this right. New issue is that my bluetooth only is seen after I come back from sleep. When you boot up, it says unavailable. dw1560 wifi/bt card

I have done that more times than I can remember. I wonder if it has anything to do with the mute switch on the keyboard. It is always lit and when you hit it, you get the mute symbol on the screen, but it does not turn audio on.

I have an 820 G2 running 10.11.2 but I can not get the audio to work. It has the ALC3228 audio chip. Are we saying there is no kext for this audio driver? Or am I missing something?

[Guide] Install 10.11 beta on HP EliteBook/ProBook/others with Clover UEFI This worked for my 2560p. Thanks

I updated mine yesterday and seems to be fine
