FWIW, I've had my 9560 for about a month and it exhibits none of these issues. I think that recent driver updates have fixed a lot of earlier problems. It's easily one of the best Windows laptops, maybe the best. That said, you can't go wrong with a MacBook Pro. I have one and it's as good as it gets. Apple cuts no corners with the hardware and OS/X is feature rich, rock solid and secure. The 9560 and the MacBook are expensive but you definitely get what you pay for with both Dell and Apple.

Bought mine a week ago and no issues other than wireless lagging. But I just fixed that by going here (www.killernetworking.com/.../killer-suite) and first I installed the Killer Network Manager Suite (it prompts you to first uninstall the current one before installing this one). Restarted, then installed the Killer Control Center 64-bit and restarted again. Everything is screaming fast, now and so-far-so-good with everything else.

I bet both of you never tried the audio jack with some high quality headphones / headset or external speakers, that are connected to the audio jack.

And maybe you didn't notice the screen flicker. 1,5 weeks ago I had my 3rd machine and like the ones before, it had these issues.

So I'm pretty sure, that I'm not alone with this problem and since I updated all drivers, I assume, that it was not fixed.

To be sure, that some driver update adressed this, I need to see relevant information on it within the driver documentation.

I just listened to some music and a couple of YouTube videos on my Apple ear buds. I hadn't tried the audio jack before so I was interested to see how it sounds. I know the ear buds aren't high quality headphones but they're all I have and the sound quality was fine with no audible crackling. I listened for about half an hour so it was a thorough test. Also, there was no overheating around the jack. As for screen flicker, I would have noticed that for sure if it was a problem. There is zero screen flicker on mine. I have the standard HD screen, not the 4K. I can't explain why you've had such bad luck with the units you have had. I'll count myself lucky.

Yes, screen flickering is only a 4k problem.

Also the audio jack issue only appears with high quality over-the-ear headphones (E.g. my Sennheiser PC360) that are sensitive to signals and good external audio speakers.

I assure you, these issues are not fixed yet.

You're not the only one - I also have screen flickers, issues with Maxx Audio, chrome and also BT mouse issues.. but can't be bothered with going through five rounds of bottom level support asking me if my windows is up to date. only thing is to wait and hope driver updates are gonna fix it - that's why macbook is better - no driver issues

I now bought a Macbook Pro. It will arrive next week. Looking forward to finally own a machine that works, after seeing Dell fail so badly at quality assurance.

It's not only you, i am also facing same problem and i am also searching the problem. If you got  solution then share it.

Any update on this? I'm writing this on my new macbook pro, which works perfectly. :) But still thinking about returning it, because its too expensive...
