Lenovo x201 Audio Popping/Buzzing/Stuttering

Okay. I'm at my wits end. This has been going on for about a year now. I've learned to ignore it, but now that I really want to use my laptop for music, it is getting annoying. There are times when playing audio that the quality starts to degrade. The audio starts to "drop" intermittently and then there's a harsh static that smooths out to an intermittant pop and then the audio drops out again as if a CD is skipping then the static. Speakers are fine because I send the audio to other devices and get the same result. When the audio device is "upset", even system sounds have static.
I haven't been able to play a song all the way through without audio dropping or static for a while now. All of my drivers are up to date (why hasn't Lenovo updated the audio drviers since 2011?). My BIOS is up to date. Windows is up to date. Night mode is off. I've read all the fixes. So far, my issue is not fixed. Has anyone else experienced this issue? Any ideas? Is it the audio processor? Or the audio management software?
It is quite frustrating because I put a lof of money into this laptop and can't listen to any music. I have an i7 intel with 8gb of ram and an SSD drive with gigabit ethernet. Latency should never be an issue. I feel I shouldn't have to figure out how to get clear sound out of a $2700 latop.

I would try booting a Linux live distro like Ubuntu from a USB Stick or CD/DVD (if you have an ultrabase with optical drive) and listen to some music to see if your X201 exhibits the same behavior.

Crackling, Popping, Buzzing Noises in Audio

Recently (within the past week) my audio has started to crack, skip, pop, buzz, and all sorts of things. I have a Pavilion g6 1d08dx laptop with Windows 7 64-Bit, 4 GB RAM, and it's about 2 years old now, but I recently re-installed the OS, about 2 or 3 weeks ago after my old HDD failed.
I notice when I hit the wifi switch, the latency gets really bad to the point where it is just static-like buzzing and crackling, whether I'm turning it on or off. I've tried to reinstall the driver (IDT High Definition Audio), and updating it, but so far nothing. If it helps, there's two other audio drivers under that section- Intel Display Audio and Bluetooth Hands-Free audio.
Perhaps an update to different drivers is available. What free software could I get to check this?
Thank you.

Can anyone help?

External Speaker big pop/buzz when connecting or disconnecting audio cable

My external speakers make a big buzz/pop every time I connect or disconnect the stereo mini 1/8" plug into the headphone jack -- if the speakers are turned up high at the time, it's enough to blow them.
This doesn't happen with headphones - just external powered sound. If I turn the external speakers way down or off, there is no pop/buzz when connecting; muting the sound through the Macbook Pro has no effect.
This happens on all external speaker systems I've tried (including the Soundsticks currently), and regardless of whether the MB is plugged in to power or not, and with or without any other external USB or Firewire devices attached. I've also tried various cables & connectors -- always the same result. This does not happen with the same speakers on an older iMac.
I've spoken to a couple other MB owners who have the same problem.
Any way around this? It would be easy enough to turn off the external speakers next the MB every time I plug or unplug -- but with it feeding 3 stereo systems throughout the house, it's a bit much every time...
Thanks!

{quote:title=Neville Mayfield wrote:}
The problem is caused by contact made with the components of the socket as it slides into its correct position. It is a small electrical charge that bridges the plug & socket segments and not related to the current sound setting on the MBP.
I assume you like high volume from your speakers, much more than I would choose to have! I do get a slight buzz & pop myself and to my recollection always have done in 23 yrs of using computers.{quote}
With all do respect, this is not the problem here. I have the same problem as described by the thread starter, and having worked in the audio producing industry for many many years I can say with certainty that what you are describing is something else.
Sure, the traditional "high-volume-on-AMP-while-connecting-signal-source" issue is still present, as it is with any product you connect like that, but this is different: when a headphone is inserted, you can hear a clearly audible "click" followed by a very noticable humming/buzzing sound. It is almost like the machine has "fired up the audio engine" and you get to hear the idle sound.
If I play music in iTunes, stop playing, leave the headphone connected, the humming/buzzing disappears after a while, and when I press play on iTunes, the same "click/humming/buzz" is heard, even though I haven't pysically touched the connector.

Can't Access Oracle EBS with a Lenovo X201 laptop

My Company runs Oracle E-Business Suite version 11.5.10.2. I recently had to get a new laptop (Lenovo X201). I can log onto the Oracle Application Home Page and select a responsibility, but when I select an operation, like Invoice Inquiry in the Payables Module for instance, I get the following message, "This tab has been recovered. A problem with this web page has caused Internet Explorer to close and reopen the tab." The laptop is running the XP operating system and Internet Explorer 8.0.6001.18702. Our IT staff can't figure out the problem. They looked at all the usual cause for problems, like pop-up blockers, etc. They also spoke to Lenovo Support without finding a resolution. We experienced a similar problem with Dell laptops that they were able to resolve. Has anyone experienced this problem with a recent-vintage Lenovo computer and found a solution?

Can you find any details about the error in Apache log files and/or Sun JRE Console Window?
If the issue is reproducible, please make sure you meet the minimum requirements as per these docs.

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying. I restored the mini from a recent backup to 10.4.9. Problem gone.
I'm glad I test updates on the mini before applying them to my Intel iMac 24. I guess I'll just hide & watch what happens before doing any more updates.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on the laptop line.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".

Libby,
Backup is unable to make a restorable by Disk Utility backup. You can restore pieces of the software as outlined in my FAQ about backing up user data:
http://www.macmaps.com/backup.html
But to be able to restore a backup with Disk Utility, you need a cloning utility to have made the backup.
I suggest starting a new thread here, where someone else could help you out better:
http://discussions.apple.com/forum.jspa?forumID=752&start=0
First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

Lenovo X201 external monitor resolution issue

Hi,
I'm having issues connecting my Lenovo X201 through the docking station -> display port -> Dell 3011. The native resolution for the monitor is 2560x1600. However, I currently can only set the resolution to 1920x1080 (ugly!) as any high resolution results in the monitor entering power save mode.
I'm using xrandr to set the video mode in my .xinitrc (running dwm). This creates a good Xinerama config for dwm.
I'm currently using the line
xrandr --output DP1 --mode 1920x1080 --above LVDS1
to set my resolution. When I change to --auto or --mode 2560x1600, or 1920x1200 etc I get the blank screen on the external monitor. I'm using the xf86-video-intel-sna driver package (I tried the -uxa as well to no avail).
Any hints?

I was able to get it by having arandr help generate the config, here's the solution that worked for me:
xrandr --output HDMI1 --off --output LVDS1 --auto --right-of DP1 --output DP1 --pos 0x0 --rotate normal --auto --output VGA1 --off

Fade effect causes audio popping

Hello,
I have had a recent issue with iMovie which is only getting worse. Whenever I use the video effect of either fade in or fade out, there is a popping sound which get written into the audio track.
I have tried various fixes but nothing seems to work. It started out as a few quiet audio pops, but now is completely warping the audio. Any ideas?
Basically I have had to go through the painstaking process of extracting the audio and then fixing it in Garageband. This works, but is tedious and takes about 4 times as long. Since I have quite a few clips to process in this way, I need to fix this issue. I really appreciate any help that others could provide with this.

If anyone else has this problem - you fix it by making sure you pan the audio to the center, not left or right.

Lenovo X201 Series Tablet/Laptop

Hi I recently bought a Lenovo X201 Series Laptop but the screen is cracked it has a touchscreen interface I would like to know can I replace the touchscreen with a 12.1inch LED or LCD Screen as I dont want to spend to much on a touch screen details of laptop is below
Product ID: 2985DMG
Specs:
Corei7 CPU,500GB Hard Drive 4GB Ram 12.1inch Touch screen.

Hi,
there is a lot matrices are installed into x201t. Models also depend of the backlight type - LED or CCFL. I'm not sure whether any supported matrices models are compatible with your laptop. Also there are different LCD cable assembly and LCD rear cover assembly depending of the backlight type.
To ensure what matrice you have and what's compatible check out on Lenovo' site parts list of your laptop by its [laptop] serial number. Support site doesn't answer a question by MTM only.
I think it's impossible to fit non touch matrice into the tablet because of the different size (width). Compare the width of x201 and x201t.
UPD
Service parts DB says your laptop has 12.1-in. WXGA LCD panel, LED backlight (300-nit LCD), FRU 45N6092 or 45N5388.

Having trouble with the trackpad on my Lenovo X201

I'm trying ot get Arch set up on my new Lenovo X201 thinkpad and I've got as far as getting X up and running. However, I'm having some problems with the trackpad.
First of all the mouse pointer is a little crazy, leaps all over the screen and is very difficult to control - any ideas on how to improve on that? Also, I've tried following various wiki examples of how to get things working (in particular using the right side of the pad for vertical scrolling) and I'm not having much luck there...
Any advice?

Never mind - it turns out that just installing synaptics fixed everything :-)

10.4.10 Audio Popping Issues: Information Check with Internal Speakers

For people with internal speakers, or those without subwoofers: Please read all the way to the bottom to find a test that will determine whether you are also having audio problems, even if you can't hear pops.
We've had a lot of discussion about audio popping due to 10.4.10, and the evidence indicates that the audio circuitry is going to sleep to conserve power, even on AC-only computers like the iMac, Mac Mini, and (at least one) Mac Pro. Some people claim to not have this problem, but I'm wondering if they just aren't noticing it.
Having external speakers with a subwoofer, set to high amplification, are key to obvious detection of the problem. Let the sound subsystem go idle for 30+ seconds (wait a minute with no audio, just to be safe), turn up your external speakers really loud, and cause the computer to make a sound. You should hear a burst before the sound plays. If you repeat the sound, you won't hear the burst. This is the sound of the audio circuitry powering on, and the speakers are amplifying it.
About 30 seconds after the sound finishes playing, if you leave the volume of your speakers turned way up, you should hear a "pop" as the circuitry is powered off. Then, playing another sound will recreate the burst.
I haven't been able to hear these sounds with internal speakers, either on the Mini or iMac. But the problem still exists, and it is detectable... if you know what you are looking for.
The burst of the audio circuitry turning on also causes a delay in the audio. The delay is a noticeable fraction of a second, an it can easily be detected if you have a repeatable source of sound. I like Terminal.app, because I use that application all day, every day. Here is how you can check to see if you are also subject to the audio problems:
1. Start Terminal.app (in the /Applications/Utilities directory).
2. Wait one minute for the audio circuitry to shut down.
3. Without typing anything else, very quickly strike and release the Backspace key.
4. If you pressed the key all the way, the program should have caused a beep. However, if the audio circuitry goes to sleep, the beep should occur after you have moved your hand off the key. This is because the circuitry takes time to power itself on before playing the sound.
5. Now, quickly strike the Backspace key again. You should notice that the sound is produced immediately as you hit the key, without the delay you just witnessed.
6. Strike the Backspace key repeatedly, to confirm that there is no audio delay. Do this about once every second or two. If you press the key too rapidly, not all of the presses will produce sounds... this behavior is not related to the issue we are testing.
7. Wait another minute for the audio circuitry to shut down, and strike the Backspace key once more. You should again observe a delay between your strike and the sound production.
If you witness delays like this, your audio circuitry is also going to sleep, and you are having the same audio problems as the rest of us. However, either because you are using internal speakers, or because your external speakers don't have the appropriate response, you aren't hearing the same bursts and pops as the rest of us.
Please try this test, and report here. I want to build a list of people who previously couldn't hear the sounds, but still have the delay. This might give us a better picture of the scope of the problem.

Distracting audio popping in T61, and no idea why!

Hey,
My laptop had been giving me trouble, so I recently did a restore to factory settings and started from scratch. Now, everything works pretty much perfectly, except the small audio popping issues I had before seem way, way worse now. I used a DPC latency checker and found out that mine is hovering around 3300 or so, with frequent spikes to 78000 (the popping is extremely noticable then), which from all my research is way too high.
Is there any easy fix for this?

Yea at first I thought maybe after it was on for a While you could see something but it Sounds Like your Display is Shot) I was going to Ask how old it was but i found at the bottom of your post this phone is a Replacement phone Yikes somebody else's trouble that was sent in to Verizon then Sent on to you.
That's why I'm not in Favor of the there Replacement Phones Program) You may get a Phone that will go to the End of your Contract and then again you may get a piece of I can't say with out get Moderated..
Well what i would DW is I would take it to your Local Verizon and see if they can Replace it for ya ) I know it'll be for the same possible Model but they may Step you up a Model.. You Just have to Check with the Store an see Hopefully they'll Warrant it for the Display Good Luck.. b33

Audio pops/drop-outs with AU bandpass

Even after I render and do a audio mixdown, I occassionally get audio pops or drop-outs (one channel or completely) of audio files to which I've applied the AU bandpass filter. Is there a way to solve this?

Make shure you sample rates and buffer sizes match. Check AMS or Sound in pref.> after application launch, sometimes it will flip automatically. Master then Slave i think > you might need more usb power

Slow performance, Audio Crackling and Stutters

I bought my Qosmio X775 7384 just 2 months ago and from the second I took it out of the box it seemed to underperformed, by which I mean it was about 1/2 as fast as my duel core 6gb RAM gateway desktop. I tried to ignore the issue and continued on with my work on my new laptop, using it mainly for music production. Every once in awhile I would get crackling and stutters, this I also tried to ignore but recently when I was in the middle of a performance it completely stuttered out and crashed the computer altogether, which was very embarrassing.
Since then the crackling and popping seems to happen during every song, either in my software, tunes, youth.... pretty much anything with sound has crackling and popping. My music software freezes and crashes and I am still extremely underwhelmed by its performance.
So far I have called and talked to support 3 times, the last time begging for a refund. They want to take my computer for repairs, IM not quite ready to give it up yet as I need it for performing. So here is what I have done.
I reinstalled every windows driver in my devices, I reinstalled every driver from this website and I have done a out of box restore. Nothing has helped.
I ran latencymon and its telling me that my isc and dpc routines are lasting too long for ndis.sys hdaudbus.sys iastor.sys and i8042prt.sys and its telling me that at least one of my problems seems to be network related and that it looks like it could be battery related as well.
Right now I have stripped all unnecessary programs and upgraded my wifi to the euro version of atheros. I believe I have done everything possible to speed up and make my computer stop popping and stuttering and it continues to do so as well as spike in the red of my latency testers.
Please help!

It sounds like you've done everything you can, especially considering that you did an out-of-box recovery. I'd agree that it's time to send it for servicing (or live with it, I suppose).

Audio pops in PPRO CC 2014

I am getting PAINFUL audio pop in Ppro with MP3 audio tracks. As I move the CTI, it will max out and blow my eardrums to pieces. Any idea as to what would cause this?
-gl

I made a post about this a little over a year ago it looks like (Loud Pop On Moving of Playhead). I've found that adding a simple single-band compressor effect to all my audio prevents the popping. Only trouble is, any compression effect (apart from Multiband (Legacy)) makes Premiere crash when trying to queue a sequence to Media Encoder (though you can still drag and drop from one app to the other).
I guess all we can do is keep filing bug reports.

Audio Pops in Windows XP

I was wondering if anyone knows why my macbook would be having audio pops in windows xp. It seems like its only when something is loading in windows. If anyone knows a solution please let me know, thank you.

Did you check the audio level at the control panel > sound and audio device?
How you run the XP, parallel or Boot Camp?
Also post this thread on boot camp forum for they might have better answer for you:
