Latency problems: audio is heard 1 second after audio waveform

I wonder if this is normal in FCE:
I have a live video of my band where I can clearly see the bass guitar riff in the audio waveform at the beginning of the song. But I hear the notes ca. 1 s later. So the audio waveform is pretty useless for setting marker visually...

wow. you are right, when monitoring through the internal speakers, the audio is heard in sync with the movie and the waveform. So the conclusion is: FC express doesn't support external audio interfaces.
I think I'll return the software, this is ridiculous. What about FC pro, does it work with firewire and USB audio interfaces?

Audio starts playing about 1/2 a second after set cursor

Sorry if this was answered elsewhere as I wasn't able to find my exact problem after searching. I'm using AA3 and Win7. The issue is this: wherever I place the cursor on the waveform, I'll hit play & the cursor moves, but I won't hear audio until about 1/2 a second after it starts playing. So to compensate, I'm having to move the cursor further back in order to hear edits, versus being able to instantly hear audio right where I begin playback (like when I had Cool Edit). I can offer more info if necessary. Thanks

Some information about your soundcard and what drivers you are using would help. It sounds as if it could either be a buffer problem or that Windows has grabbed back your soundcard when Audition stopped. Make sure that in Audio Hardware Setup the box for Release ASIO Driver in Background is NOT ticked. Also a good idea to turn off Windows Sounds.

Just installed windows 7 Ultimate using Boot Camp. Problem is when I chose to boot the windows partition, I get the windows icon on the sreen showing that it is starting, but few second after I get a black screen

Just installed windows 7 Ultimate using Boot Camp. Problem is when I choose to boot the windows partition, I get the windows icon on the screen showing that it is starting, but few second after, I get a blank screen. I suspect a driver (screen) issue, since I also installed Parallell using the boot camp partition and that works fine.
Do anybody out there has an ideal of what to do to solve this issue.

Audio latency problem SOLVED

Hi Everyone, I've recently purchased a Satellite A6665, and found myself having latency problems when using real-time audio processing software such as Ableton Live and/or Nuendo.
Fortunately, I was able to solve the problem installing the ASIO4ALL Drivers.
Here's the link to their website.
http://www.asio4all.com/
I hope you find this useful.
Best regards,
Sebastian.

Hello sebastian, I have the same problem as you with my tecra a11 s3540 and I "solve" it in the same way as you, with asio for all. Any way, I thoung that this problem its saying something about some problem with the usb hubs on our laptops... It will be great if some one could give us any ligth about this... its not normal that a sound card (in this case a focusrite saffire usb 6) only works well using asio for all. I say this becouse I try my sound card on my old laptop (hp dv4000) and its works very nice, no latency problems.
wich sound card do you use?
cheers

Exchange latency problem after cisco switch implementation

I recently upgraded our network with 9 2950's and 1 3560G switch. I've configured 2 vlans, one for servers and the other for clients and everything seems to work ok except communications to our exchange box. Since the upgrade users receive a message box "requesting data from microsoft exchange" several times during the day. For some users it only appears for a second or few seconds, others it's up for a minute or more.
I've run diagnostics on the exchange box and everything there seems to be ok, but i'm wondering if maybe I missed something in the port configuration on the switches that would cause this type of latency problem. Anyone ever see anything like this before?
Regards,
Dave

Should this be all VLAN interfaces or just the one the exchange server resides in? I looked up this command and it states it is used to keep tcp sessions from being dropped. Is there a command that shows the number of sessions which have been dropped on the switch?
the show interface command only gives me this:

The Superdrive on my MacBook Pro ejects audio CDsa few seconds after they are inserted. This happens with both prerecorded CDs I have bought in music stores AND with audio CDs I have recorded myself, on the very same computer, via iTunes.

The Superdrive on my MacBook Pro ejects audio CDs just a few seconds after inserting them. This happens both with original audio CDs I have bought in music stores AND with audio CDs I have recorded myself, on the very same computer, via iTunes. The same does NOT happen with data CDs (e.g., stuff in mp3 format), which are read just fine. This behaviour started a couple of weeks ago, until then everything had worked just fine for years. I am running iTunes 11.1 under Snow Leopard 10.6.8. Any idea?

Thinkpad Edge E440 Random Lags, Stuttering, Latency Problem.

Dear All, I bought Thinkpad Edge E440 almost two weeks ago. The problem is it randomly lags and stutter without reason. For example I was writing documents on Microsoft Word, plays music on foobar2000 and doing some light browsing (only few tabs) but randomly the music lags for 1-2 seconds. It doesn't skip, it lags or stutter (sorry I don't know the right term). Also sometime it took awhile to open a new tab on firefox web browser while usually it took instantly.
Another example is I play two online games, World of Tanks (WoT in short, a tank simulation game) and Ghost Recon Phantoms (a shooting game). When I play both game, the gameplay went smooth but randomly it lags or stutter like 1 second on more, then it went smooth again and then stutter again. The game doesn't became slow (which is called FPS drop if I am not wrong), the display just stop moving and mouse/keyboard become unresponsive during the lag/stutter period. On the other hand I also played WoT on my Pentium 4 PC and it went smooth without any lags, though of course the settings is inferior to my E440 laptop (Ghost Recon Phantoms can't be played on my Pentium 4 so I won't compare it).
Also sometimes the audio sounds 'spiky'.
As I searched online, people said that this is called/related to Latency problem and I should use LatencyMon to check it. After using LatencyMon I found several 'culprits' which causes big latency such as NDIS.sys, ACPI.sys, ATAPORT.sys, storport.sys, etc. I also tried to disable cpu throttling, power management settings and such but the problem doesn't go away.
I am sure that there is something wrong with my hardware because if its caused by settings such as cpu throttling, power management (which I think is software-related) then won't this happen to everybody? I mean, I asked a fellow E440 user and he said that his laptop is fine and my problems doesn't occur on him.
I have phoned Lenovo Customer Service. I was using Windows 7 Ultimate. At first they told me to do clean reinstall and install the drivers in the order the CS give me. I did clean reinstall 4 times to try different driver and program installation sequence to see if I might find a way to fix my problem, but I found no solution (I tried Lenovo CS driver install order on the last clean reinstall). I even tried running LatencyMon after clean reinstall before installing any drivers or updates but the LatencyMon still reports big, 'unhealthy' latency.
Lenovo CS then told me to do hardware scan on Lenovo Solution Center. There are warning on the Nvidia GT740M stress test but the CS told me that the results are good. His last solution is that I should go to a Lenovo Service Center to check for the problem there.
I moved to Windows 8.1 to see if the problem will be solved but too bad it's not. I have ran hardware scan for 5 times, there are two times(or 3 times I forgot) that there is warning on Harddisk SMART short self-test, 2 times warning on Nvidia GT740M stress test, one time scan finished with no warning. Even so, the end result for all the tests is 'Passed'.
I think the problem lies within my harddisk (or something related to data transfer) since when I browse my local drive in windows explorer sometimes it took a long time for the icons to load but sometime it just loads instantly. And I am not sure what that Nvidia stress test warning has to do with.
Also I only use the stock 4GB Ram. Could this related to the problem? Though when I look at Windows 8.1 Task Manager the memory usage rarely goes above 60%.
Last but not least. I plug a wireless mouse on my laptop which I use mostly for playing games, but in the end I switches between mouse-touchpad-mouse and so on during working too. Sometime my touchpad suddenly went unresponsive for few seconds but my mouse is still usable during that moment. Then after I move my wireless mouse, my touchpad become responsive again. Any idea why this is happening? I think this is probably because touchpad driver not perfectly compatible with Windows 8.1 as I don't recall having this trackpad issue on WIndows 7.
Can somebody help me? Does anyone else ever had the same problem as I do?
I am sorry for the really long explanation. Your response will be greatly appreciated.
Thank you.

Hi All, sorry for being a while for a long time.
First of all, I should say that I am not sure if my trackpad/pointing device problem is related to the lag/stutter/latency problem so I should have made two different thread instead. Sorry if anyone got confused with this.
@rallygion, the first OS I used on this laptop was Windows 7 64bit. If I remember correctly I don't experience the trackpad/pointing device problem back then, maybe I was just forgotten tho. I am using Windows 8.1 starting sometime before I made this thread. Now the problem has gone worse, sometime the touchpad & red dot in the keyboard won't work for a whole day so I must use external mouse.
At first I thought its compability problem with Windows 8.1 but now I think the hardware has problem too. However, the keyboard is fully functional.
@waqs, thanks for your suggestion! Unfortunately it doesn't solve the lag/stutter/latency problem.
@ghasan, our problem is quite similar except I didn't use the M.2 SSD. One thing I notice is the disk activity sometimes jumps to 100% when the lags happened.
The problem doesn't lie with the laptop specification is inferior. Fyi, when I play music on foobar2000 it took few second for music to start playing (foobar says 'starting playback..') while on my pentium 4 desktop (which I still use) the music plays right after I clicked the song.
Also, eventhough I've closed all my applications, leaving only music player and microsoft word/firefox, the music which is playing lags (randomly stops for a moment).
The lags also happened when watching videos. I played video on Media Player Classic, turned the statistics on. There happen to be frame drops sometimes. Not framerate drop, just frame dropped. I mean, I think framerate dropping has relation with computer power while in my case the frame just randomly drops, which 'damages' the video, not slowing it down.
I am sure that this is hardware-related problem. I am going to take my laptop to service center but not now since I am in need on my laptop now.
I will give update later when I have gone to the service center.

Is there a better way to re-render audio waveforms (after changing media files)?

I'm shooting documentary footage on RED cameras at 6K resolution. That generates a large amount of media. The RDC format records R3D media files in 4GB chunks, which is actually relatively short compared to my hours-long media captures. I've discovered that it's very handy to simply delete the R3D files from the RDC folder in cases where nothing is actually happening at that moment. Since each R3D media file is timecode stamped, these actually stay in sync with my master audio track. And Premiere Pro sensibly places gray diagonal bars where the underlying R3D files are missing. All good.
What's not good is that Premiere Pro confuses itself about the starting point of the PEK files. Instead of simply greying out the part of the audio waveforms that are missing due to the missing media, it shifts the *waveform* to start at the location of the first R3D clip that is present, which is wrong. If I clean the cache, quit the project, restart the project, and let it rebuild the cache, the audio waveform is correctly drawn.
An ideal fix for this problem would be for Premiere Pro to recognize that if it re-links media it should re-render the audio PEK file. An OK work-around would be to make it easy to just re-render the PEK file for a given media clip.

A slightly quicker way to do what you described for an images is to select 'Duplicate version' instead of 'New version from Master' and then 'Remove adjustments' from version 1. This will leave you with the first version as the 'before' and the second version as the 'after' without having to use L&S.
If you need to do this for 108 images, it might be quicker to do the following:
Export Masters for all 108 images.
Reimport these into a new project (called 'before', for example)
You will then have a new project with the 'before' images and your original project with the 'after' images. You could then build an album to group all of these together. When you've finished with the 'before' & 'after' images (build your web gallery or emailed them or whatever), simply delete the 'before' project.

Steve

DPC Latency problem

Hi everyone ;)
I'm trying to fix my pc. I'm experiencing DPC Latency problem and it causes audio stuttering. I'm running Windows 8.1 x64. When I'm running LatencyMon, it shows me that some of my drivers give a really high latency.
I was trying to install new drivers, turn off my soundcard (Sound blaster Audigy SE). The problem started to occur, just after a clean install of Windows 8.1, two days ago. Earlier I did not have any problems
with DPC latency. The weird thing is, that I do not have any audio problems when playing games. The problems occur when I'm listening to music or watching movies. Thanks for your help and sorry for my bad english.
PS My computer specs:
Gigabyte GA-G41M-Combo (rev. 1.3)
4 GB DDR3 RAM
Nvidia GeForce 450GTS
Intel Core2Quad 2.5GHz
Creative Sound Blaster Audigy SE
Wireless mouse and keyboard (microsoft ones)
Drivers causing DPC Latency:
ntoskrnl.exe
USBport.sys
dxgkrnl.sys
nvlddmkm.sys
ataport.sys
CLASSPNP.sys
rspLLL64.sys
Thank you for your help!

Hi,
First, please let me know what player you use to listen to music or watch movies? I considered the codec conflict.
If there is any third part player installed, please remove it to check the issue.
If the issue still persists, please upload the .etl file here for further research.
Keep post.

[ PROBLEM ] Audio Control app wont recognise card properly

Hi
I have a X-Fi ExtremeGamer card in my Win 7 home premium setup and am struggling to set it up properly.
Long story short , I pulled out the X-Fi card and tried the onboard audio as I was getting an issue with the audio playing around using the creative drivers ( volume changes mid song, positional audio in games was often unusal ).
The Realtek stuff wasnt too bad but I wanted to try my X-Fi card again, it is suppose to be better after all.
Anyways...
I disabled the onboard audio , safe mode and cleaned all the realtek drivers out and any lingering creative drivers with Driver Sweeper, used CCleaner to clean up the reg and rebooted.
Installed the BETA drivers from creative and the audio works fine, but when I try use the crystaliser or other SB features the app complains
" The audio device supported by this application is not detected. The application will exit. "
I installed Daniel_K's drivers from a CD ISO he put out a while back, and the applications worked fine but the audio dropped in and out, so I downloaded the official creative drivers for my card and OS, and the application worked fine again but as with Daniels drivers the audio dropped in and out so I reverted to the beta drivers... and the audio dropped in and out as well.
I worked it out to being the volume controls on the creative 5. speakers , which every set of speakers I have bought from creative have had the same issue, the volume slider on the cable... after some use it messes up the audio and it becomes safer just to adjust the volume in the software.
After deciding the issue was with the volume slider on the cable, I wanted to re-install Daniel_K's driver pack so I could access the other features, now it suddenly doesnt recognise the device anymore, nore does the official none beta drivers from creative, nor does the latest PAX drivers ... all report the same issue:
" The audio device supported by this application is not detected. The application will exit. "?
I am starting to tear my hair out here, the audio works and the card is recognised in the Device Manager as 'Creative SB X-Fi' , I have clean the drivers , the registery , used the patch that fixes a bug where the update wouldnt recognise cards properly , re-re-re-re-re-re-re-re-re-re-re-re installed the drivers.... carefully EACH time.
I triple checked I was downloading the Win 7 64bit OS ver of the X-Fi ExtremeGamer drivers.
What now ?
ALSO Who thought it was a bright idea to put up the volume to 87% when you install drivers ? It also unmutes the volume if you mute it before restart, and it puts the volume back up to 87% if you dare to lower the volume before rebooting the PC to complete the install.
( NOTE: It only does this after the initial reboot to complete the install, subsequent re-boots leaves the volume alone )

I give up...
I sent a form to the tech guys , detailing the problem and outlining the steps I took to fix the issue...and they direct me to http://support.creative.com/kb/ShowA...aspx?sid=55438?, oh I can use Device Manager to uninstall , oh and Control Panel - Programs to unistall the Creative stuff ( note: I am being very sarcastic here ).
This is the information I sent the tech:
Detailed Problem Description:
Creative audio application does not recognise SB X-Fi card , card audio functions just cant control the feature set. Error msg : " The audio device supported by this application is not detected. The application will exit. " Suspect nVidia installing of HD audio drivers causing 4 (four) additional High Definition Audio Devices to appear in the device manager screen. Unable to uninstall these devices as Win7 auto re-reinstalls with generic MS drivers, can only disable. Creative SB X-Fi card listed in audio devices as 2 - SB X-Fi. Suspect the audio control application looks in the first slot and doesnt recognise the device and fails, doesnt look at the 2 ( second slot ? ) Tried a full uninstall including going to safe mode and removing drivers with Driver Sweeper, CCLeaner to clear out registry entries and removed the card, booted to windows without the card , re-seated the card and re-installed the drivers. Forum entry for this problem at: http://forums.creative.com/t5/Sound-Blaster/PROBLEM-Audio-Control-app-wont-recognise-card-properly/td-p/57930
Thank you
and this is the advice I got ...
Thank you for contacting Creative Labs.
To avoid installing the incorrect driver on your soundcard, we suggest that you do a full uninstallation using the guidelines, steps provided in our website. Shutdown your PC then take out the card and make sure to place it on another slot. Second, disable your onboard audio and if your graphic card comes with any audio support as well, disable this feature.

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro.

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro (8 Core 2.93GHz). When I run the Mac Pro with 2 x 2Gb RAM it takes 4 seconds before the gray screen, chime and spinning wheel appear.However when I expand the RAM to 20GB the grey screen and chimes appear after a long 20+ second black screen.
The RAM modules are paored 2 x 4GB Crucial CT51272BA1339.M18FMR and 6 x 2GB SAMSUNG M391B5673FH0-CH9, all DDR3 ECC.
Reading articles on the internet, I thought it may be damaged RAM modules, but I have completed memtest and all are okay. I have tried changing the pairs around and if I use any paired 2 modules the Mac Pro starts normally, only when I try running more than 2 modules the delayed start up happens. (black screen 20 Seconds)
I also have tried PRAM and SMU resets after changing the RAM setups, and the issues always occurs when I have more than 2 modules. As you can see I have 6 SAMSUNG modules and even with identical modules the issue happens, when increasing the RAM to more than 2 modules.
The Mac Pro runs fine after the start up screen and can see all the modules, but has anyone else come across this issue, or have any ideas as to why my Mac Pro is taking 20 seconds to start up with 20 GB RAM?

Hi there. Thanks for your comments.
I have tried all the different combinations of RAM setup, and as stated in my initial topic, the Mac Pro boot up time only slows when I have more that 2 modules. Where I place these does not seem to make a difference.
I have taken the Mac Pro to an Apple Reseller technician yesterday and they where not able to find any RAM errors. Apparently the boot up time is within Apple's acceptable parameters for this set up.
Could anyone that is running a Mac Pro 2009 with more that 4 modules of RAM, please let me know if the boot up time is normal. ( the time it takes from pressing the power button to seeing the gray screen around 16 - 20 seconds)
Or is anyone else having the same issues?
thanks for your responce

Reader XI freezes 2-3 seconds after I open it, every time!

This problem started when I downloaded reader XI. It didn't happen in reader 9, or whatever the previous version was on my computer. The little timer on the right moves clockwise 2-3 clicks and then it freezes. About 20 seconds after being frozen, it closes. Same thing happens when I try to open a pdf. No error messages or anything. I'm running windows 7 on a dell latitude E5530 (laptop). No idea what's going on. Here's a screenshot. Help please. Go easy please. I'm not super smart when it comes to computer jargon.
