[SOLVED] Dell Latitude E6540: static noise from headphones in High Sierra

Hi,

I read and followed Jake's comments in this thread so now audio is working but I am getting static noise from the headphones for E6540. I already put CodecCommander.kext in S/L/E

I have abm_firstpolldelay=16000 

Any idea why its doing that or what do I need to do to fix it?

Thanks
