Dell Precision M6800 - Excessive Static on Headphone Port

Me again :)

 

The machine is working 99.99% smoothly now, but today I discovered something that's not working right: the headphone port.

 

I plugged in my headphones, and got blasted with super loud static. If I turned system volume up full, I could hear system sounds and stuff.

 

Is there a software fix for this? I will boot into Windows 7 (installed on another drive) to check if it works normally there, and to rule out a hardware fault.

 

Thanks,

OK, I'll try that. I already have that kext installed, but it's an older version.

 

However, new problem. WiFi and Bluetooth have suddenly decided to stop working. This is independent of the sound problem, and I didn't do anything to cause it. They were working when I shut down last night, and dead when I started up today.

 

I'm running hardware diagnostics, to rule out any hardware faults.

No. However, after wasting like an hour reinstalling kexts and clearing caches, I discovered that the Wireless switch got flipped to the off position. Duh!

 

I totally forgot that was a thing!!

 

Oh, well. Lesson learned.

 

Anyway, back to the original problem. I'll give it a try and report back.
