T400 sound issues: sporadic stuttering and crackling

I recently purchased the new T400 laptop and am having some issues with sound quality. Frequently, the speaker sound choppy and broken. On top of this, I can hear a crackling/popping interference coming from the speakers. I first noticed the issue while listening to music over my wireless connection. I have tried listening through the headphones port and the problem persists. Restarting the computer usually fixes the problem temporarily, so did opening a song in i-tunes and playing it for 10 seconds until the audio corrected itself. Since then, I have noticed that the problematic sound quality is not confined to music over the Internet, with similar effects occurring in i-tunes and during the windows start-up and shutdown music theme. In addition, I have had my computer lose all audio capabilities twice until the computer was restarted; the mute was not on, the volume was all the way up, and all of the volume controls were balanced.
Is this a harware or software problem and how do I go about troubleshooting my computer? I read the Lenovo troubleshooting page for audio issues, but since my computer is brand new, I didn't know if it was nessisary to try and intall the latest drivers and BIOs?
Any suggestions would be much appreciated. Thanks!

Hello,
first thing to do is burning recovery dvd´s, you´ll need 3-4 dvd´s.
Then save your C:\SWTools folder, there are all needed drivers in it, especially gfx drivers are important.
Then I would mention to install new audio drivers with System Update, see if it fixes crackling.
If not, then try a Linux Live Cd, boot with it to check, if it´s a Vista (software) or hardware problem.
The last thing, if Linux has shown no problems, is to install Vista from your recovery dvd´s.
Cheers
Andreas

ITunes Stream Stuttering and Crackling Noises (Temporary Work Around Option

Note: If you don’t take the time from your busy schedule to address these suggestions being provided in this and future upcoming series, then by all mean continue with what you were doing before and continue to experience the frustrations and problems. The series is not meant to be a cure-all for the problems you are having. But the information will go a long way toward correcting and improving a lot of issues that you may be having with your system. Think About It !!!!!!!!!!
I listen to the radio a lot using the iTunes player as well as listen to music that I have transferred to the player. When a problem occurs it aggravates me to no end especially if it is occurring when I am try to relax to my music. At times I am also experiencing the stuttering and crackling issues in the 7.0 update that has been recently released. The following information can be useful in temporarily correcting this problem until Apple comes up with a patch to resolve this issue. If you choose to proceed with implementing this information then you assume any liability that may occur during your attempts at using and applying this information. This information has so far suited any needs that I may or am currently having to date personally.
1)Quick Time Preferences – In the Quick Time Preferences\Audio tab check to make sure that the settings are at the default level. Your platform may reflect a different khz Rate. On my platform my default level will be the following:
Rate: 44.1 khz
Size: 16 bit
Channels: Stereo (L R)
When I listen to my music I like a good quality stereo sound so I have my audio sound routed from my laptop to my CD or Video jacks in the back of my stereo. Stereo System: Pioneer SX 251R Receiver. External Speakers: 2 - 8 ohm Yamaha.
Make sure the Safe Mode box is unchecked. Close the Quick Time player. Now, when you begin experiencing the stutter problem there are two immediate steps that you can try to correct the problem:
1)Stop the stream or the music that you are listening too and restart the service each time that the event occurs, (In my case the events that have been occurring has not been consistent when they do occur. Close monitoring in place on all connection ports. Running Snap In’s deployed: IPSec Monitor/MMC Console– Currently monitoring IKE and IPSec Statistics for any changes. To run this snap in properly the Event Monitor must be in the running state and actively logging events in the Administrative\Event Viewer Folder) I will also be configuring Dr Watson to generate a Stack and Dump file log to the desk top in the event of an unexpected occurrence. or,
2)If that does not correct the problem then try the following: Go to the My Computer folder and open it up. When you have done so, Right click the Local Disk and enter the Properties section. When the Local Disk Properties box comes up, enter the Tools tab, in the Error Checking section, place a check mark in the “Automatically Fix System Errors” and click start\yes. Back out of that and close all running programs including firewall in the tray next to your clock and reboot the system.
Once you have rebooted run the Disk Cleanup utility and the Disk Defragmenter utility. While we are using the Disk Defragmenter lets take an extra step to insure that we defragging the hard drive volumes as much as possible. Click on the analyze button a second time. If there are any entries in the box highlight the first entry and run the Defrag utility a second time.
Tip! If you would get in the habit of running defrag process regularly on a daily basis it will help improve the overall baseline performance of your machine.
Last Step: Open your player and try again.
If you are still experiencing the problem and it hasn’t leveled out to your satisfaction then there are two additional steps that I have personally used or am currently using that may help with your issues. The steps will involve installing a small batch file program and a hot fix patch.
User Profile Hive Cleanup Service– (Batch Program) Open your Browser and type in the following address: www.microsft.com once the page has loaded look for the search bar in the upper right hand corner of the page. In the search bar type in the following: “User Profile Hive Cleanup Service”. Once the search result page comes up click on the first result to bring up the proper download page. Before you can use this batch program you will be required to go through a short validation process before you can download the program. The validation process is to ensure that you are running a genuine windows platform.
Overview
The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.
On Windows 2000 you can benefit from this service if the application event log shows event id 1000 where the message text indicates that the profile is not unloading and that the error is "Access is denied". On Windows XP and Windows Server 2003 either event ids 1517 and 1524 indicate the same profile unload problem.
To accomplish this the service monitors for logged off users that still have registry hives loaded. When that happens the service determines which application have handles opened to the hives and releases them. It logs the application name and what registry keys were left open. After this the system finishes unloading the profile.
Once you have downloaded and installed the batch file close all running programs and reboot. Now, ‘This is important”, lets determine if the batch file is properly running after installation. Go to Start\Help and Support. Once the Help and Support Center comes up click on the following link: “Use tools to view your computer information and diagnose problems” under the “Pick a task” section. Once the page has been loaded in the left hand pane click on the “Advanced System Information” link. Once that page has been loaded click on the following link: View detailed system information (Msinfo32.exe).
Once the System Information box is loaded look in the left pane and open the Software Environment Tree and click on the following link: Windows Error Reporting. If the batch program is properly running you should see the following entry: “User profile hive cleanup service version 1.6.30.0 started successfully
&#x00a”. The ending symbols may be different on your platform.
Now, we want to go to another location in your system to verify this entry and that this service is properly working again. Pull up your “Control Panel” and enter the “Administrative Tools” folder. Once there enter the “Event Viewer” folder. Then enter the “Application Folder”. If the service is properly working the following entry will be logged: User profile hive cleanup service version 1.6.30.0 started successfully, Event ID 1001. If for some reason this program is not functioning properly a different error code other then the Event Id 1001 will be generated and logged in this folder. Also if one is generated you will want to verify if it’s a genuine error. To do this you need to go back into the help and support center Advanced System Information link and click on the following link: “View the error log”. If anything goes wrong a corresponding general entry that was logged in the Event Viewer will be logged in this link verifying that a problem had occurred. All of the information in the logs will be useful in your trouble shooting efforts. To date I have not had any measurable conflicts to occur while using this batch program to date. Closing Overview: when this program engages it will target itself at the Kernel System only at shutdown and startup. A corresponding entry will be made in the folders that I have described above stating that the program had started or failed.
System Restore Feature and USB Device’s – Event Viewer\System and Application Folders\Event ID SR 1 (Hot Fix Patch) – I have noticed that some folks are loading and unloading iTunes in attempt to correct problems. Also, I see by the forum board that a lot of folks are having a lot of problems with their iPods. Think about this for a moment, iPods will have their own unique set of drivers to operate from. I am going to attempt to explain an experience that occurred with me last year on this issue. When working with USB Devices it is important to keep your eyes on the Event Viewer folders for the following event id being logged: Event ID SR 1. This is especially true if you are using your System Restore Feature. The main folders that you want to keep your eyes on are the “System\Application” folders.
I have not witnessed any specific Software Applications generating this code in general at this point in time. But when it comes to Software and USB Devices I have personally experienced a situation that did cause a SR 1 entry last year. Example: My wife has Sevier medical problems. When we travel I keep a USB Flash Drive on my key chain with her medical information installed in case of an emergence. The Medic Alert E-Health Key was a new device that came out that had bugs that needed resolved just as with iTunes 7.0. The short of the story is that the flash drive was conflicting with the System Restore Feature, which led to additional problems such as conflicts in the Add/Remove Utility. I could not properly unload the Uninstall .Dll files when trying to uninstall the flash drive itself using the Add/Remove Utility. During a conversation with a Microsoft Support tech I was informed that other unloading issues had also been identified in the Add/Remove Utility. I could be wrong but I think there is a patch available that would help with unloading issues while using the Add/Remove Utility. To keep an eye on any possible loading/unloading issues that I may have while using the Add/Remove Utility, I use the following program to determine if there any issue’s that I need to deal with: (30 Day Trial Program-Fully Functional)
http://www.mikasalonen.com/remove/?remove40
Program Name: Remove 4.0. All of the information you need to know about this program will be summarized in the provided link. If anything: USE IT !!!!
NOTE: This SR 1 patch is only a temporary hot fix. They are suggesting that we wait until the next Windows XP service pack release that contains the hot fix.
Article Id : 888402
Last Review : June 01, 2006
Revision : 1.5
Also keep this in mind. The only time that you want to become concerned about the SR 1 issue is when you notice an increase in the number of SR 1 entries in Event viewer logs. If you are logging two (2) or more events then I would begin investigating the problem. Again, In my case the System Restore Feature was identified as the initial cause of conflict when the conflict first occurred when loading the USB Flash Drivers. So, if you suddenly notice this entry in the Event Viewer then you can pretty much bet that you are experiencing a USB issue that is conflicting with the System Restore Feature. But there is a Hot Fix available to temporarily resolve this issue as I have stated. Go back to the Microsoft link that was provided. When the page loads, in the search bar in the upper right hand corner of the page type in the following KB 888402. Be Advised – if you have to resort to this measure you will have to contact the Microsoft Support Team directly by phone to receive this patch.
When you talk to the tech you will need to provide the following information: A brief description if the Event being generated in the Event Viewer as well as a brief description of the problem that you are having. Once the tech has verified the information he/she will e-mail the hot fix to you in a zip folder if I’m not mistaken.
System and Third Party Drivers
Drivers can be another source of conflict that can have a direct impact on how your system operates. I have already given you an example of this in the System Restore/USB Devices section. They can also cause unexpected stability issues. In addition to that malicious Root Kits and Trojans can download drivers on your hard drive without your knowledge further complicating matters. So, before I close this information out let me show you how we can quickly gather and display a listing of all drivers that are currently installed on you hard drive by using a very simple program. (This program will be a 15-day Trial program).
Program Name: My Drivers 3.11
With this program you will be able filter out all preinstalled drivers that came with the system at the time of purchase, thus exposing the remaining Third Party drivers and as well as the Unknowns. If you know what your doing I would take this time now and disable the drive(s) in question if removal procedures are deemed necessary once you have obtained the driver listing. My overall objective with this program is to immediately determine if there is anything out of the norm with the drivers overall.
A download link is unavailable at this time. The web site appears to be under construction at this time.
As a final step on this issue I suggest keeping an eye on the Device Manager for any sudden “Yellow Warning Symbols” appearing within the Device Manager Tree Structure.
Print this information off and us it as a reference point. Any new helpful hints that I can think of will be posted as soon as I can squeeze the time in.

T400 Sound Issues

New T400 - 7417TRU....random sound issues...comes and goes. Running XP. For example, while listening to a CD, sound comes and goes and then starts warbling. Any ideas?
Solved!
Go to Solution.

we are also having random touchpad mouse issues. seems to have a mind of it's own. This unit was purchased Mid-March 2009. Went into the settings for the touchpad and basically turned all special features off. Still does it...randomly...not all of the time.
Solved the problem by downloading and installing DVD Firmware update from Lenovo. For the mouse touchpad issues, went into the settings and turned off all settings, leave the touchpad in basic configuration. All is working great now.

Guitar Hero 3 - stutters and crackl

Hiya all. I'm currently using driver 6.0..24 (the one that DriverExpires showed how to extract on his website). In the past, sound really hasn't been a big deal for me - I have it on lightly when playing games, and for listening to youtube videos and the like. Anyhoo, I just purchased Guitar Hero 3 today, and was hoping that the audio would be great - I have a nice set of 5. surround sound speakers from Logitech. Unfortunately, while the sound itself is decent enough, I've noticed a lot of slowdown when playing the game. My first assumption is that it's related to the sound card (a SB audigy 2 ZS) because GH3 is a very sound intensi've game, and ... well ... I'm not using official CL drivers because there isn't one. But I would like to know if there's anything I can do, with what is available now, to not have so much stuttering in playing this game. As an aside, the 'vista rating' on my computer is 4.4, and I turned down the in game settings, but I'm still getting stuttering and a bit of crackle while playing. Does anybody have any advice? Is there a new driver I can try (I haven't visited this site in a few months). To the administrators, is there any news at all of a new driver being released for the Audigy 2 series? If the answer is 'no, there will never be an official driver', I'm fine with that, because at least I'll know. But really, any advice and information would be greatly appreciated.

I'm running a Audigy both on Vista 32 and 64 bit.

Sound Issues in Mac and Windows

I'm new to the forums so please don't flame me if there is a solution out there. I have a month old MacPro on 10.4.8. Over the past week my headset sound has been very spotty. Sometimes I can hear music with no vocals. My games play ambient sound but I can not hear characters talk. Videos on the web play with no sound.
If I fire up iTunes my songs play only instruments for left and right channel but there are no voices. I have the same problem with the rear output on the G5 now. Is this a hardware issue? In Windows using bootcamp I have the exact same problem... or sometimes no sound at all..
Any ideas?

Macs and PCs obviously render web pages differently. Unfortunately, many web designed optimize their code for IE, leaving many people with pages taht render slowly or not at all.
Some things I have discovered to speed up my Mac. Go into the network sys pref and make sure that the type of connection you are using - ethernet or Airport - is listed first. Go into the configuration and turn off IPv6 or if it is off, turn it on. IPv6 is new and not all ISPs support it. Having it in the "wrong" state can cause a problem.
Also, if there is anything in the DNS server box, write it down and then use "4.2.2.x" where "x" is 1-6. Some DNS servers are slow and using those values on my Mac and PC made a big difference to me.

Stability issues, playback stutters, and occasional crashes with 8.1 update

Hi all, I'm having a bunch of weird stability issues with Premiere CC 8.1 on Mac OSX Mavericks 10.9.5. I'm working on a medium sized 1080p project with about 60-80 pieces of media totaling about 60GB. Footage was from a DSLR and was transcoded into prores 422 for editing.
Initially after updating to 8.1 and creating my project I didn't notice any issues but after progressing further in the edit and adding additional video tracks, titles, and a couple small AE comps I've noticed a pretty drastic falloff in performance. I will get occasional crashes and playback is slow to respond. After pressing spacebar or L it'll hang for anywhere from a few seconds to a minute before actually playing back. During playback it'll get caught up and hang and I have to stop playback and wait a bit for things to return to normal. I'm also experiencing performance issues scrubbing through footage in my project bins.
I've tried some basic troubleshooting like cache clearing, preference trashing, video driver updating, and un- and reinstalling to no avail. It'll sometimes work ok but usually displays most of the above issues. I've been using premiere for a bit over a year now and haven't experienced any of these issues on my other older machines, let alone my new MBP. Premiere is usually very snappy and misbehaves rarely.
Technical bits:
Premiere CC (2014) v8.1
15" Retina MacBook Pro
Mac OSX Mavericks 10.9.5
2.6 GHz Intel Core i7
16 GB 1600 MHz DDR3
NVIDIA GeForce GT 750M 2048 MB
1TB Apple SSD

Hi Ian,
Is it possible to reinstall your GPU drivers? I have heard that this might be at the heart of this issue. Also, trash preferences. Here is the full list I'm asking Mac folks to try.
Sign out from Creative Cloud, restart Premiere Pro, then sign in
Update any GPU drivers
Trash preferences
Ensure Adobe preference files are set to read/write
Delete media cache
Remove plug-ins
Repair permissions
In Sequence Settings > Video Previews, change the codec to one that matches your footage
Disconnect any third party hardware
Reboot
Report back if anything here worked for you.
Thanks,
Kevin

790i SLI crackling and popping sound issue solv

No, not by a Creative product but by a competitors PCI?sound card.
I am no longer experiencing any crackling or popping sound during movie playback and durring games on my eVGA?790i system in SLI mode on Vista Ultimate 64.
The sound quaility and performance are excellent.
I will be returning my Fatalty Pro this weekend.
I strongly suggest you do whatever it takes to fix your sound cards Creative. At least one of your competitors was able to design a very good sound card that has none of the issues that the X-Fi does with the 790i.
Your continuing to sell a clearly defecti've product has cost you my business, a customer that has been using your sound cards for 0 years.
Gamers dont want excuses, we want results.
If you cant provide them, we will buy from a company that can as I have already done.

so, i went with it at a service who handle toshiba warrancies too. They tested the hardware and said everything is ok, must be a software problem.
So i did what you asked, installed it out of the box, and it doesn't give me the same bad problems, but they still occure but seldom than before.
So it must be a software problem indeed, which toshiba didnt resolve with the new bios version 2.50.
Anyway, the problem is another one. I used to install windows in a custom way on 50 GB so I could use the best of the rest of GB for other partitiions. Now, with out of the box installationg, i cannot shrink too much of C partition (the one with windows), it doesn;t let me , so i am stuck with 119GB on C. Isn't there anything to be able to take like 60GB from C to another partition. I tried to defragment with it was 0 result.
Thanks
I am also waititng for other advices to be able to resolve the software problem with audio.

Audio Crackles/Stutters and Slows Down on G42-230US

My laptop's sound has been making crackling static noises and has been slowing down and stuttering at odd intervals. It makes no difference if I use the laptop speakers, headphones, or external speakers, and so far all of my media player programs have shown the same results-- I'm thinking it's a software problem, but none of the drivers I have downloaded from Support and Drivers have been effective in solving the problem. The problem is distracting enough that I can't use my media files without the sound becoming very distorted and incomprhensible at times.
Has anyone had this issue, and if so, can you tell me what I might do to fix it? Thanks.

hey, i also got this problem. when I'm watching a movie or something like that the audio crackels when i open something else it seem like the audio laggs whenever the notebook has to think
so HP or someone else help us!!!!

Help with Audigy 2 Zs and crackling sound ..

For the past 5 months or so ( not long after I got the product ) I have been getting this periodic issue with the sound ...
I'll start to notice a popping and crackling sound coming from the left channel when loud sounds issue from the game ( multiple games ). After a while I figured ou ttha tI could :
a: Reset all my settings to Default , Then reconfigure my surround
or
b: Reinstall and/or patchthe current driver set ...
Both seem to fix the issue for some time then it all returns within a month or so .... It's a rela pain to have to keep configuring my Audio settings every month.
My system specs are
Asus A7N8X DLX Rev. 02
AMD 3000+
Gig Corsair XMS
BFG 6800GT 256
Audigy 2 ZS
Raptor 74 Gig
and some Altec Landsing Speakers ( I forgot the model number )
Any idea what could be causing this ?
Thanks in advance.

I got the fix for you twellons. Just go in the audio control panel and mute the midi/synth in the panel and you will have the fix. My system specs are close toy yours amd 2800xp, nforce 2 a7n8x dlx ver .04 and a original audigy card. Now creative has to address this issue in new drivers. Also download the demo of contract jack and when you load the game and the game menus comes up, scroll through the options in that menu like new game, load game quickly and you will here that popping noise in only the left speaker. and when you do that fix that i mentioned above, no more popping . So try that out and please get back to me and tell me if it worked or not. That issue was tough to figure out.
P.S. You owe me

Focusrite Scarlett 2i2 clapping and crackling issues with Logic Pro x new iMac 27"

Hi, I have just purchased a brand new iMac and downloaded Logic Pro x, I also purchased the Focusrite Scarlett 2i2 interface. I have downloaded the drivers from the focusrite website and everything is set up, when I plug in guitar or mic I get really bad clapping and crackling to the point where the sound cuts out altogether. I have changed buffer size and sample rates and everything else I can think of but nothing seems to fix the problem. I also deleted the 2i2 drivers and logic and reinstalled them both but still have the same issue, when I record using the iMac built in mic everything is fine so it's deffinately something to do with the interface. I am waiting to hear back from Focusrite tech help. Does anyone else have this problem? Any help would be appreciated.

I'm having a similar issue which might indicate that the problem is not your interface.
Yesterday I migrated all my stuff from my 2009 iMac to a brand new iMac 27", and when I did a quick test to play back some old projects in Logic there was loads of annoying clicks and pops. My interface is a Roland Octa-Capture.
I also noticed some weird CPU spikes from time to time, which I never had on my older, much less powerful iMac...

Crackling and popping sound when playing music and watching youtube videos

there is a crackling and popping sound when i watch videos on youtube or play music/videos using vlc media player and windows media player. recently it has gotten to a point where it happens when windows is starting up or even when the laptop is required to play a sound for example when i plug in a removeable hardware such as thumbdrives

Hi @donnabail ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP 2000 Notebook and getting a buzzing or popping sound while playing music and watching Youtube videos. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook that might have caused this.
You can try this
1. Right click the Speaker icon in the bottom right corner.
2. Click Playback Devices.
3. Click Speakers.
4. Click properties.
5. Click the advanced tab on the Properties window.
6. Change the Default Format drop-down to the highest quality.
7. Apply the properties.
8. Click OK to close the properties window.
What happens if you right click on the video while playing a video and take the check out of hardware acceleration. Shut the browser down and restart the notebook.
Have you checked for an update on the Active X.
Please let me know how this goes.
Thanks.

Example-CD : "Tracy Chapman , Telling stories" is not able to import . I have more such negative cases. But in other cases it works fine and the sound is great.
The firmware at the inbuild CD/DVD DS-6E2SH is the latest version.
What can I do??

hi b noir,
I don't no about virtuel drives like you mententioned. In the mean time I have rebooted the XPS and run again the iTunes diagnostics. I think the back - chance in the registry was not ready to use.
