Yes, but not much more - 100? maybe 105? It's an angle that's smaller than what I would set it at for normal use.

rlin,
When were you holding the keyboard perpendicular to the ground, did gravity pull the lid inward (towards k/b) or outward? In the following video at the 1:00 mark, the macbook air is being held in the former way.

I was testing mine in the latter way, as illusrated in the following vid. http://www.youtube.com/watch?v=N3vEfZznH18 -
Just wondering how the hell do you get the finger gesture to work on this UX31.... Ive been trying the last half hour and the only finger gesture that work for me is 2F click. The rest are not working at all....... I have the latest driver 9.1.7.7 Is my UX31 faulty or mouse pad suck?
-
Interestingly though, connecting the combo jack to the line-in of an audio system works fine. The left/right channels are properly separated, and as far as I can tell, the distortion is gone. I've tried this successfully with two different cables and audio setups.
Do you mind seeing whether your UX21 does the same thing? Does this information give you any clue as to what might be going on? -
My hypothesis is that the ground conductor in the jack is either not making contact with the return conductor in the plug or is not properly grounded. The ground conductor is either the S or the second R in the TRRS jack - depending on whether Asus is following the convention used by iPhones (Left-Right-Ground-Mic) or the convention used by some other smart phones (Left-Right-Mic-Ground). I don't have a headset with a combo plug so I can't test which, but it shouldn't matter for just audio playback. Since the T and R get now cut off from their common return, the signal through one tries to return through the other. This results in attenuation because of the increased impedance, and cancellation whenever the signals correlate. The resulting signal being transduced by the headphone drivers will be the difference of T and R, with one channel opposite in polarity relative to the other. To our ears, this will sound like the same "side channel" mix in both ears, since we don't perceive the polarity difference when wearing headphones (the outputs won't acoustically interfere with each other). This also explains why the distortion will be different depending on what you are listening to (different songs/genres have different styles of stereo mixing).
If you have a decent audio system, my guess is that your system is giving the Left and Right signal some alternate path to ground, instead of through the "return" conductor back to the laptop battery.
I have some experience in audio production, but no formal training in electronics. So I know what I am hearing is a difference signal, but the rest is just my way of theorizing how it could happen. If someone who is knowledgeable in electrical engineering would please confirm or correct the logic of my hypothesis (i.e. IF the headphones have no return path, THEN we end up with an attenuated difference signal), I would be most appreciative.
Update: I tested on my roomate's Bose system and yes, the problem went away, matching your observations. I would expand my hypothesis to add that any amplification would give the signal an alternate path to ground, so this problem should not occur in any powered speaker systems.
What remains to be discovered is what kind of behavior results from plugging in a true combo plug (headset) into a jack with this symptom in question. Noxxle had no problems with a headset, but he didn't have the problem with headphones either. Kanishka42 or yxo2, do either of you guys have headsets that you might be able to try out?
I'm also curious as to how widespread this is. I've scoured the web and so far I only know of the three of us with this problem (me, Kanishka42, yxo2) and we all have the UX21, not UX31. However, at least one person (noxxle99) with a UX21 has reported he does not have the problem.
Neither Newegg nor Asus has gotten back to me or responded to my requests for replacement RMA (Newegg historically has responded within 2 business days, and Asus states they respond within 48 hours - it's been much more than that). -
I'm not sure his problem is exactly what we're seeing (I wouldn't describe it as a "buzz"), but it's perhaps suggestive of problems with the UX21's assembly process -- especially since the reviewer is on his second UX21 already. -

rlin unfortunately I don't have a headset so I can't test it out. Even if it does work though I know none of the earphones I tested work properly, at the moment my cellphone produces better audio than the laptop.

I wouldn't recommend what you did as a workaround. The difference in impedance of the new return path would still distort the signal, albeit not nearly as severely as before. There might be some faint echoes that weren't previously present before. -

Sigh, guess I get to see whether Amazon or Asus wants to deal with this. -
Hi,
I wrote the Amazon review complaining of the buzz. It is the typical dirty 60 Hz buzz you get with badly grounded or shorted equipment. I did not notice any of the weird channel phasing issues you folks have described, so it appears Asus are shipping units with multiple kinds of defective audio jacks.
I'm willing to believe that there are some units out there with audio jacks that weren't dead on arrival, but both of mine were.
The buzz is reproducible:
- With Sony MDR-V6 headphones
- With a Sony consumer-grade 2.1 system
- With Yamaha HS50M monitors connected via a Mackie 1204 mixer
- With my mid-90s component stereo system
- On AC power
- On battery
- With Windows booted
- With Ubuntu booted from a USB stick
- In the BIOS configuration menu
The buzz is quieter:
- With the UX21 unit powered off
The buzz only stops completely:
- When I remove the audio plug from the UX21's headphone jack
Other things I plugged into these systems were:
- Asus Eee model 1015PE
- Apple Iphone 4
- Apple Iphone 3G
- Acer Iconia Tab A100
Only the UX21 units produced the buzzing sound. It was so bad that I was at first legitimately worried that I'd somehow damaged the speakers I use with my Eee... after some testing with the first unit and the above equipment I was convinced the first unit was defective. When the second unit buzzed exactly the same way I gave up on this model altogether. Listening to music is one of the primary applications for my computer systems, and one that can't do that has no place in my home network at all.
The first unit was about 4 dB louder than the second one, but both were loud enough that the buzz totally drowned out typical classical music recordings (I heard mostly buzz and a little music) and was clearly audible during quieter passages of popular music.
I'll leave it to others to pick up the pieces with this disappointing offering. While I wait for my refund to clear, I'll try to decide between an Asus 1018P and an 11-inch Macbook Air. I got two UX21 units in a row with the same defect, and it's a waste of my time to summon replacement after replacement until I get one that works. -
Can you direct me to a song that really brings out the noise? A link would be appreciated. I'm going to run some tests.

Here are two pop tracks that many people should recognize, produced in such a way that jacks with the distortion problem completely destroy them.
Britney's Hold it against me : In the verse the vocals are pretty much gone, leaving just reverb, backing vocals, and instrumentals. Then in the chorus, the vocals are boosted and the instrumentals drop out. The dubsteppy part of the bridge is just wacky.
Pink's Raise your glass: In the verse the vocals have some weird phasing affect on them. In the chorus, all low frequencies drop out. There is a huge loudness difference between the verse and chorus too.
If you're planning to generate the side channel manually in a sound editor to hear what the distortion sounds like, you won't mimic it exactly but you'll get pretty close. The left and right channel digital analog converters in consumer-grade sound cards are never precisely in sync nor have precisely the same amplification factors. These in themselves are normal, but in a system with the return cut, they reduce the "side channel" effect and add some comb filtering. There should be echoes in the signal too due to impedance mismatches, but I haven't noticed this. -
What is the dead pixel policy on the UX31 with Asus? I read that Asus offer some policy about dead pixels. I just checked mine and I found 2 of them.

That's too bad, CMR. The quality control must not be rigorous.
I just tried two different headphones in my UX31, and I don't have any buzzing. -

(warning: mostly a rant post)
neither asus nor newegg have responded to my technical support / rma request emails. it's been 6 and 3 days, respectively, so i called them up today.
asus says their warranty process involves me resetting the ssd, sending the laptop to a service center across the country, waiting 10-14 business days for repair, and waiting for it to be sent back. that's at least 4 weeks of downtime.
newegg is willing to send a replacement within 3 days of receiving the defective one, but can not guarantee the replacement won't have the same issue. and they do not allow returns on laptops.
i'm very bummed out at the momment. i'm not sure i like being an "early adopter" anymore. i've spent way too much time on this, time that i should never have had to spend and will never get back -

Thank you, that helps very much. Those values seems like good values. I don't think a 800us spike will affect audio performance. For me I think its ok as long it does not spike in the red.
How long did you leave it on? It can be good to have the program on for 15-30 minutes to catch occasional high spikes. It can also be a good idea to see how much it spikes when the cpu is stressed with a program like prime95. -
hopefully it'll fix the power mgmt issues!

They sounded completely normal at first. However, if I twist the headphone plug slightly, I can create some strange distortions. In fact, the sound might completely drop from one side. The distortion or lack of sound would remain even after I stopped twisting. I felt like I had to tune the plug just right to get the full sound.
*edit* Is it normal to get the described effects when twisting an audio plug? -
As much as I like ASUS and thoroughly dislike Apple, I am returning my laptop tomorrow and buying a Macbook Air. This laptop was clearly rushed to the market and in my professional opinion there should be people fired for having next to zero quality control when releasing a $1000+ laptop to retail stores. For those who are keeping it I sincerely wish most (if not all) of your problems are fixed.

On a normal laptop you'd just pry the screen bezel off (after a few screws) and the hinges would be exposed where you could tighten the nut.
I don't think getting the bezel off the UX is going to be quite as simple. You probably should either return it for an exchange to your retailer or RMA it to ASUS. -
Does the wireless card have Bluetooth enabled? ;< I use a Logitech mouse and keyboard that connects to my computers via the unifying USB mini-receiver. Since the Zenbooks only have 2 USB ports (one 2.0 and one 3.0), I was wondering if the wireless card in these Zenbooks has Bluetooth. Although I'm not even sure there are keyboards and mouses that connect via Bluetooth either.

kanishka42 said: ↑It was on battery power using the default battery saving power profile. Firefox was open with several tabs. The spike occurred while loading a new page.
I tried leaving it running for longer (~10 minutes), and I do indeed see some occasional higher spikes, including one or two in the red zone. Prime95 and CrystalDiskMark don't seem to lead to higher latency. However, launching apps, watching videos, and increased WLAN traffic roughly correlate with spikes that are normally in the 500-800us range. I can't pinpoint any specific action that causes yellow or red spikes more often. It just seems random.
Oh -- I should mention that I'm on a UX21. I think you originally asked about the UX31.Click to expand...
How far up in the red? What was the highest spikes? Sometimes the really high spikes can come when a few different things happens on exactly the same moment. Does it spike in the red when you run it with the power adapter and set the power management in window 7 to "high performance"?
Resplendence Software - LatencyMon: DPC, ISR and pagefault execution monitor
This is an other similar program that measures the dpc latency and record which driver or process that is responsible. You could try it if you want to now the exact issue. I think the most common things that effect dpc latency is the network-card, the graphics driver and sometimes the antivirus-program.
Yes but I think they should not be to much different since they seem to have the same components except different processor models. It would be nice if also someone else with the UX31 could try though. -

just got my UX31.. and I'm having the same hinge problems.
Its really loose at all angles.. I suppose if you place it on the table top its fine but if you shake it a bit it moves quite a lot
I also seem to be missing quite a lot of keystrokes.. I'm thinking of maybe returning it -
Sorry to hear about the problems everyone is having.
Personally, am LOVING my Zenbook - from the packaging down to the solid construction.
My only downer is the fact that it came with 40 GB off the 128 GB on the SSD already being used. Seriously, Asus?
19 of that is Windows, ok.
But then there is eSupport > eDriver files - they look like drivers for the hardware there as backup, over 4 GB? I have no idea if I can delete it, will I need it. I guess I'll have to back it all up. But I really shouldn't have to!
2 Other iso's - 3 GM each, I don't know if they are boot files or something else. And no readme in the iso when you mount them. Really poor form.
One thing I did delete was a 380 MB Screensaver file from Asus!! 380 MB???!!!!!
Anyone have any luck/tips on getting rid of the bloatware? -
I'm also getting wi-fi issues (but perhaps its due to my source)
I think I managed to fix it by changing the settings in the profile..
But the strength of the wi-fi seems to be weaker than other notebooks? -
