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

[Analyzer 0]

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

Did you repair permissions and rebuild your cache after adding CodecCommander to /S/L//E?

Yes and I had to keep on doing it until it registered the AppleHDA_ALC292.kext so audio can work.

 

sudo chmod -Rf 755 /S*/L*/E*

sudo chown -Rf 0:0 /S*/L*/E*

sudo touch -f /S*/L*/E*

 

sudo chmod -Rf 755 /L*/E*

sudo chown -Rf 0:0 /L*/E*

sudo touch -f /L*/E*

sudo kextcache -Boot -U /

 

But still static noise from the headphones
