I wonder if they've fixed the coil whine problem with this iteration. That's the sticking point for me currently.
There's a lot of static on the headphone port too, which is disappointing.
I had no idea this was actually a thing before this morning :(
It seems to only happen when there is graphics stress -- using "semaphores=1 i915_enable_rc6=7 i915_enable_fbc=1" seems to help, and once I started playing videos with --hwdec it was quieter also..
As it only happens during video, and I usually have headphones or the speakers going at those times I'm not too bugged by it yet..
Doing a kernel compile or something noisy in a term doesn't seem to trigger it..
