Latency issue causing sound distortion

I have explored a number of posts and discovered that my relatively frequent sound distortion matches a latency problem occurring every 15 secs, give or take a sec, as high as 29000us, but usually about 20000us.
I have disabled the common things in device manager one by one without change in latency.
I couldn't see a TV tuner in Device Manager, but uninstalled software driver without any change.
dv7 4002tx No WT507PA#ABG running Win7 64 bit
Software added since new is Microsoft Office 2010 Small business, Access 2010, and Windows 7 Professional
HP Advisor says it is up to date
This question was solved.

I have finally had this problem resolved by HP. Their initial option was to ask me to re-install from the image on the hard drive, which got rid of a lot of marketing software initially installed when sold, but it had no effect on the sound/latency issue
I initially discovered that the ACPI-composite battery driver in Device Manager seemed to cause the every 15sec 20000us latency spike, because when I disabled this, the problem disappeared. However this driver was not what was fixed to resolve the problem.
HP phone care finally rang me back with their solution, and it was as follows (and didn't involve the battery ACPI-composite driver). Despite using the HP support assistant, neither of these changes was being flagged.
1. I was told to go to the HP website and download a recently uploaded BIOS update for my notebook - all it seemed to say it fixed was a graphics issue. This bios update in fact immediately solved the problem, though there were still some latency spikes up to 8000us without any audio effect, and without there being any regularity of appearance.
2. I was also told to download the audio driver which had recently been uploaded (since I first noted my problem). This resulted in latency spikes never exceeding 2000us (and usually not exceeding 600us
I find it interesting that the support assistant did not recommend these updates, and the audio driver was still being flagged as up to date when specifically tested, despite an apparently better one being available.

Need help diagnosing cause of printing issue w/ image distortion

Hello, I'm looking for some expert advice for my print issue with image distortion (see above) on my files once setup and proofed by my printer.
I have a large PSD background file out of photoshop (CMYK, 170mb psd) that is being placed into an InDesign document. No preflight errors, all correct SWOP cmyk settings, and I keep having issues where images distort on my printers proofs - they seem unable to explain the issue and can't offer any other suggestions beyond ("just try resaving/uploading again" which of course has an added fee with each upload...).
The files are all fine on our end: on-screen, on our cmyk proofs, and our saved PDFs/packaged files. But everytime our printer opens these they seem to have these distorted image problems - scrambled images (almost as if there was a ghosted transparent image in the distorted area), strange lines (see above, and color distortion (usually greens and pinks, see above).
Is this an issue with my settings/file formats? Maybe the issue lies on our printers end? I'll keep checking this throughout the day and provide quick answers to anyone who can help me get to the bottom of this.
Adobe forums have been a huge help in years past so I decided this was by best bet for a resolution from those who know more than myself (or my printer), thanks for taking the time to help!

Sound distortion issue when uploading iMovie

Each time I try to 'Share' a movie I created the sound distorts once it's uploaded. It's driving me crazy! I've read other posts re this problem but no resolutions given. The sound just ends up a bit fuzzy - it's fine until it's uploaded to file or iTunes etc. Does anyone else know what the problem may be?

Solved it by downloading win 8 drivers for audio from sony support... followed condor's suggestion http://community.sony.com/t5/VAIO-Windows-10/LAPTOP-VAIO-SVT15112CSX-audio-drivers-that-work-with-windows-10/m-p/516334#U516334

Sound distortion in most recent episode of Lost

Hi all,
the most recent episode of Lost plays on my Apple TV with really bad sound distortion starting from 4.23 and continuing to the end.
I have a series pass so the episode downloaded onto my Apple TV. The file that has synched with my Mac plays fine in iTunes. I've changed the sync options to remove that ep of Lost from the appletv and then synched back, but it still does it. The episode is Lost s6 e6 'Sundown'. Has anyone else had this issue? I don't want to watch it on my laptop, I really need it to work on the Apple TV!
Thanks
Caspar

Not the best solution, but at least you'll be able to watch this episode on the Apple TV.
Either:
Switch Dolby Digital Out to Off in Apple TV's setting. The episode will then play the Stereo AAC track instead (which is fine, btw). Problem is, you'll have to switch Dolby Digital Out back on if you want surround sound back for other content.
Or:
Download an App called Subler.
Open the HD Episode of Lost in Subler.
You'll see that subler lists the video track and two audio tracks. The Digital surround track is not ticked, but this normal and is not the cause of the 'static problem'
Select the surround track and click the delete button.
Save the file and re-sync to Apple TV.
It will now play in stereo.

Speeding up youtube video sound distortion

when i go to speed up youtube videos cause i have so many subscriptions speeding them up saves time and most of them i can without losing anything but lately the sound at 2x gets choppy and above that is impossible to watch i know it seems an odd complaint it vastly slows down my youtube subscriptions

operating system windows 8.1
browers chrome 42.0.2311.90 m internet explorer 11.0.9600.17728
Adobe Flash Player (2 files) - Version: 17.0.0.169
Shockwave Flash 17.0 r0
clicking on any video on youtube loads fine going to settings then speed normal speed works fine going up to 1.25 on chrome makes the audio crack every 10 seconds or so , going up to 1.5 the audio starts cracking badly and makes the video almost stop for 5-10 seonds and 2 makes it even more un-watchable, on internet explorer the sound distorts more and more but it doesnt stop running like on chrome but is inaudible 1.5 to 2 i disabled all extensions to chrome not sure if this would be a youtube issue or a flash issue but its not isolated to chrome, i updated windows today and even checked my sound settings to see if there is a change

AA3 Rewire latency issues...

Why is it when I Re-Wire AA3 with anything, Reason4 for example, when I load redrum there will be a 50 msec delay or so when i hit the pads before I hear it. Im tired of this. The reason I use AA3 with beat production is for recording samples, guitar, etc on top of whatever midi is in Reason. Plus, I like to mix in Adobe. Well, I LOVE Reasons mixer but I hate Fruity Loops and when I use that I like to use Adobes mixer. But whats up with this latency? This hasnt always been a problem and I cant think back to when it first started. It worked fine when I used my Fast Track Pro to record, now in addition I have a Fast Track Ultra8r that is used most of the time and ive never had any latency issues in adobe itself or reason by itself on this computer.
Is aa3 really that much of a resource hog? Anyone else have the same problem or any ideas?? I cant play keyboard when i hear the sound 2 secs after i hit a chord it reaallly messes with my ears and throws me off beat. It would be cool if this happened during post production where I could just up my sample rate. but its happening while recording.

Most obvious to try first is to try changing the I/O buffer size - go into the Audio/MIDI Setup (Applications>Utilities>AudioMIDI setup) and adjust there. Generally speaking you're looking for the lowest value you can get away with before you start to experience digital distortion and drop-outs. I think the default setting is 512 samples - you should be able to reduce it quite a bit depending on your computer's processing power. Hope that helps.

Sound distortion in iTunes and not in other players

Hello,
I've been experiencing some terrible sound distortion with iTunes that I don't have with any other player (WM player for instance).
I installed version 6 and this doesn't fix any issue.
This doesn't cause any problem when transferring files to iPod but still, have to be fixed!
Has anyone a clue or already fixed this in windows XP?
Thanks

Hi,
I have same problem with my iTunes 6.
You can try this(Helps for me):
1. From the Start menu, select Settings and open the Control Panel
2. Double-click the Multimedia or Sound, Speech & Audio devices icon,
3. Select Sound and Audio Devices, click the Advanced Audio button
4. Select the Advanced tab then
5. Select the Performance tab and find the Hardware Acceleration slider control
hardware acceleration should be set at full.
sample rate conversion quality should be set at best.

Bus latency issue

I am sure there is a simple solution to this ... I haven't found it on my searches yet.
In Logic 7.2 I am routing BFD auxiliaries to one bus and running some overall compression and eq. Now I have latency on the bus and it is lagging behind the rest of the tracks. What can I do to compensate and pull it back up to speed with the other tracks?

I am sorry no one has seen fit to help you with this problem however help is at hand please take time to read this very carefully. I believe this is your answer you seek, The reason I have gone into such depth is simple so that you will have a grounded understanding of how logic address the problem and also what plugs in Logic have Latency within them by default. Well here goes
Logic Pro 7.1: Full Plug-in Delay Compensation can cause late recordings and increased latency
In Logic Pro 7.1, if you set Plug-in Delay Compensation to All, any new tracks you record will be late and out of sync with previously recorded tracks. You may also experience increased latency when playing Audio Instruments live. Here are some concepts behind the issue and tips for resolving it.
About full delay compensation
One of the new features in Logic Pro 7.1 is full delay compensation across busses, aux channels, and outputs. This means you can place plug-ins that normally induce latency on busses, auxes, or outputs, and the audio routed through these plug-ins will be in sync with everything. Logic achieves this by calculating the amount of delay caused by plug-ins assigned to a bus, aux, or output, and delaying the streams sent to other busses, auxes, or outputs by an appropriate amount to line everything up. This ensures that all tracks will be synced to sample-accuracy.
Example scenario
To give you a better understanding of what's going on here, let's say you have a simple song with a few drum, bass, guitar, and vocal tracks. All the drum tracks are routed to a bus with several plug-ins inserted that together induce 500 ms of latency. The vocals are routed through another bus that has a set of plug-ins that induce 250 ms of latency, and the bass and guitar tracks are routed straight to the main outputs without going through any latency-creating plug-ins. If latency were not corrected, then the bass and guitar tracks would play 500 ms in front of the drums. The vocals would be 250 ms in front of the drums but 250 ms behind the guitar and bass.
With full delay compensation engaged, Logic Pro will delay the streams sent to the outputs for guitar and bass playback by 500 ms to line them up with the drums, and will also delay the bus the vocals are streamed to by 250 ms to line them up with the drums and guitars. The precise calculations are handled for each stream automatically. During playback and mixing, the delay created to compensate for plug-in latency is imperceptible, but it can cause problems if you do any tracking after turning on full plug-in delay compensation. These recordings will be late because of the delay that Logic imposes to compensate for latency. The degree of lateness will vary, depending on which plug-ins are in the signal chain.
Eliminating latency
There are several ways to deal with these latency issues. The best way is to simply avoid setting up any signal routing that involves using plug-ins that create latency on busses, auxes, or outputs until you are done tracking. Once you start mixing, go ahead and set up any routing you like, including setting Plug-in Delay Compensation to "All."
If you can't avoid recording tracks after setting up such a routing scheme, then bypass any plug-ins you have on busses, auxes, or outputs that create latency, and change your delay compensation setting from "All" to "Audio tracks and instruments" while you are recording. You can quickly bypass plug-ins by Option-clicking on their inserts in the Track Mixer. You can toggle the Plug-in Delay Compensation setting by choosing Logic Pro > Preferences > Audio > General, or by setting up a key command for "Plug-In Delay Compensation: All." This key command will toggle the delay compensation setting between "All" and "Audio tracks and instruments." When you finish recording, re-enable the plug-ins on the busses and toggle the delay compensation setting back to "All."
Note: Bypassing plug-ins on Outputs will not eliminate the latency that they create. To eliminate it, you must remove these plug-ins entirely from the Output's insert slots.
If you are recording audio, another strategy would be to choose Audio > Audio Hardware & Drivers, then disable Software Monitoring. You would then need to monitor your recording via an external hardware mixer, or third party software mixing application that may be provided with your audio interface. When Logic is not providing software monitoring of incoming audio, then it can correctly position audio recordings even when full delay compensation is enabled. It is important to note that this technique will not help with recording Audio Instruments.
For the same reasons as described above, you may get increased latency when playing Audio Instrument tracks live if the delay compensation is set to All. As with recording audio tracks, try to complete any Audio Instrument recording for a song before turning on the full delay compensation. If you find it necessary to add a new audio instrument recording after setting up a signal routing that involves latency-causing plug-ins on busses, auxes, or outputs, then follow the same advice stated above for adding recorded audio. You may also notice that the meters on busses, auxes, or outputs that have delay-compensated plug-ins will not be in sync with the tracks that are routed through them—however, the audio will be sample-accurate. Additionally, the Song Position Line's visible position will not be compensated. Unless you are using an exceptionally large set of delay-compensated plug-ins, this should not be particularly noticeable.
Another effect with delay compensation set to All is that MIDI tracks triggering external sound modules will be out of sync. This is because Logic has no direct control over the audio output of external devices. A possible solution for this would be to route the audio outputs from the external MIDI devices to inputs on your audio hardware and monitor them through Logic. This way, the audio streams from the MIDI devices can be compensated during playback. Using Logic's External instrument to route MIDI to your external devices is an ideal way to work in this situation.
Here is a list of Logic plug-ins that cause latency:
Adaptive Limiter
Limiter
Multipressor
Noise Gate
Silver Gate
Linear Phase EQ
Match EQ
EnVerb
Space Designer
Denoiser
Pitch Correction
Pitch Shifter II
Vocal Transformer
Some third-party Audio Unit plug-ins may also cause latency—refer to the user guide for the respective products to see about this. All plug-ins that run from DSP cards such as the PowerCore or UAD card have inherent latency. Logic Pro compensates for the latency of any of these third party plug-ins, but as with Logic's own plug-ins, avoid assigning those that exhibit latency to busses, auxes or outputs until you are finished with tracking.
You may also find that simply bypassing plug-ins that run from DSP cards will not be sufficient to correct the latency they induce. If you are using these plug-ins, there are a couple of ways to deal with this. One would be to remove the plug-in entirely while you are recording tracks, and then re-insert them when you're done recording. Be sure to save your settings for each of these as a preset first, so that you can recover the appropriate settings when you re-insert them. Taking this idea a bit further, you could save the entire channel strip setting for each bus, aux or output that uses plug-ins that cause latency and then easily reassign everything for each channel in one go.
I hope you will get something useful from this good luck

Possible audio latency issues due to acpi.sys

Hello, I use Vista to run the digital DJ program, Traktor. While I've never had any latency issues before, they recently started cropping up and I ran LatencyMon to see where the problem could be. It appears that the problem may be the service, acpi.sys,
as it had the highest execution of 1.2, which is fairly high. I've tried using Process Explorer and entering into the BIOS to turn off acpi.sys, but wasn't able to. Is there really any way of disable this service?
Thank you.

Hi,
As this issue did not occur before, system restore can be under consideration.
To disable the feature, you can also go to Device Manager, expand System Devices.
This issue can occur due to hardware or software conflictions. Let us try the steps below to narrow down the cause of the issue. Please check if we can boot in Win7 normally:
Device Clean Boot
==============
In this situation, your system will only have the basic hardware devices and it should be more stable. If it is inconvenient to unplug the devices, we can disable them in Device Manager. Please refer to the following steps:
1. Click "Start", type "DEVMGMT.MSC" in the Search textbox and press Enter.
2. Expand "Sound, video and game controllers".
3. Right click on your Sound Card, select "Properties"
4. Click "Driver" tab, click Disable (Disable the selected device). Click OK
5. Please use the same method to disable other hardware such as: Modem, network card, CD-R drive. Please note some devices such as video adapter are not available to be disabled.
6. Please restart the computer. Can we boot in Windows Vista properly? If so, please continue prepare a clean boot to troubleshoot.
Clean Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior.
Refer:
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
http://support.microsoft.com/kb/929135
Note: Ensure that you put your computer back to normal startup mode after completing the troubleshooting steps. Steps are available in the article given above.

Sound distortion when using hdmi cable

HP G62 notebook pc(Laptop) windows 7
I have sound distortion when i connect laptop to pc using HDMI cable, happens after 10 minutes then sound is ok again then 10 minutes later sound distortion again. Sound on laptop is ok. Not HDMI cable because used other laptops and its works fine.

I'm having this issue as well. Just posting to let people know there is more than one person with this issue. I have a pavilion dv5 laptop

Video Latency Issue On The Mac Book Pro 2.4 With Leopard 10.5.5

Gear: Macbook Pro (early 2008 model) - 2.4gigs cpu 2gigs ram - all the latest updates... no other applications running during the test
Hi folks. Currently I am having a latency issue when trying to record directly into iMovie using the built-in microphone and iSight camera. Basically, the video seems 5 - 7 frames late to the audio. I found that a good way to demonstrate this issue was simply doing a few handclaps as a test.
This is a quick handclap test displaying some video latency during recording with the iSight camera in iMovie 08.
- Just download this link — and import it into iMovie 08 - Here is a link to a zip file that you can import into iMovie 08 - It's 2.5meg - .m4v export - Also it was recorded as standard format and audio midi setup app: audio was set to 44.1:
http://www.brainbeast.com/37/clap-1-large.zip
- Play from beginning. As soon as you hear a clap sound — pause with the space bar - then back up before the clap with the left arrows
- Then click the right arrow several times until you hear the beginning of the clap sound ( This is the audio: start frame)
- Now — you will notice the video still has an open hand. At this point click the right arrow, counting as you go several times until you see the hand close. This is the amount of frames that the video is late to the audio. For me it seems to be an average of about 5-7 frames late.
Unfortunately iMovie 06 nor QuickTime will not scrub audio as you go frame by frame with the arrow keys so you cannot test it there. If you have some other application such as final cut Pro, you could test it with that.
! IF YOU WOULD LIKE TO PERFORM THE TEST YOURSELF:
- Just record a new movie in iMovie 08 - using the built-in mic and i-Sight camera — and see if it is also slightly out of sync
Note: to be as fair as possible — I did a slow handclap ( in order to not challenge the frame rates) - also, in order to get the maximum volume I used an open palm ( clap on the palms with your fingers spread out as you can see I did.)
Please let me know if this latency appears to be the same for you as it does for me.
Q: Is it just my machine or does it happen to you too?
Q: Does anyone know a way around this latency issue?
Q: Does anyone know if Apple is aware of this latency issue?

I am experiencing the same incredibly frustrating problem as well. When I record directly into iMovie
'08, the video lags the audio by a fraction of a second.
I have tried shutting down all other applications and having only iMovie up. Same problem.
I tried recording the video into QuickTime instead of iMovie and experienced the same problem. (Which makes me think it is perhaps a hardware or operating system issue.)
I tried the technique suggested here and on other sites of "double-dragging" the clip from the Events pane into a project (one normal drag and one Shift+Cmd drag) so that I had the audio and video as two separate tracks. After muting the audio on the video track, I then attempted to slide the audio over to sync it with the video, but even down at the 1/2 second zoom setting I didn't seem to have enough granularity to move the audio so that it was exactly in sync with the video. I was wishing I could use the arrow keys or something like that to move the audio just one frame at a time.
All I want to do is record a video directly into iMovie '08 - this would seem to be something trivial to do!

Sound Distortion AP 11 and 12.

I'm experiencing sound distortion and weak signal after AP upgraded to 11. I downloaded 12 and I still have the problem. Windows 7.

AP? You mean Flash Player?
12 is a beta, so it's not a good idea to use that to remedy playback problems as it's a test product.
Are you experiencing audio issues elsewhere? Windows Media Player, iTunes, Quick Time or VLC for instance?

Why am I getting sound distortion when connecting iPad 2 to amplifier.

I am getting sound distortion when connecting iPad or iPod thru amplifier using AirPlay or 3.5mm to rca cables. Also the sound has far too much bass. No problems when connected in car.

It sounds like a mismatched impedence. What are you connecting to? the output from the jack is intended for headphones, and is not just an audio out.
Try turning the volume on the pad way down, and use the gain on your amp, and see if that minimizes the issue.
There is a pure audio signal for both channels on the 31 pin plug, but you would need a special cable to use it. I would bet they are available if you google. Although I have read that the 31 pin signal is not filtered like the headphone output, so while it is a pure audio output, there may be some noise in it that would need to be filtered.
Try google for a 31 pin cable. ( the input for the car is probably built to take a signal from a headphone output, while your amp may be expecting a lower power signal)

Sound distortion every 20 sec on Satellite C

When listening to audio both with and without headphones, every 20 seconds or so the sound output becomes distorted for several seconds and in some cases this sound distortion also causes the computer display to freeze completely.
My PC is a Toshiba Satellite series C running Windows 7.
Any suggestions please?

>every 20 seconds or so the sound output becomes distorted for several seconds and in some cases this sound distortion also causes the computer display to freeze completely.
This looks a little bit like system freeze.
In such case some processes which are running in the system background load the CPU and this cause short system freeze.
Possibly you have installed a lot of different applications and therefore its mostly impossible to say what software could be the troublemaker at the other hand it would be interesting to know if you ever try to reinstall the system and to clean the HDD.
A new OS installation might be the key.

Sound Distortion - Music and Events only

My iphone 3gs 3.1.2 seems to have a software issue playing sounds. when playing music from the speaker or using the headphone jack the sound is incredibly distorted and unrecognisable, even with the volume low. i have done several soft and hard resets which fix the problem for a short time and it then returns, sometimes part way through a song, video or application. interestingly the sound whilst making standard voice calls is ok, but maybe this is not as noticeable as it is at a lower volume and has less bass tones. Any ideas?

I am having the same problem. Have sent an email to customer support to see if any feedback. Since music file that was purchased on iphone plays fine when synced to PC and played in Itunes I suspect is hardware or software problem with Iphone 3GS. Seems to have been happening ever since I purchased though.
