T42 Audio stutters when WLAN turned on

Hi @all!
We've got a weird Problem over here: we have some T42 Thinkpads with Win XP Pro and all Updates (Win and most recent drivers from Lenovo) installed and the audio-playback gets stuck when the WLAN is activated. When we disable WLAN (via FN-F5) stuttering stops and normal playback works like a charm.
Problem occurs in every Player we tested (iTunes, Windows Media Player, WinAmp etc.) and with all Power Schemes and different amounts of RAM installed.
Installed WLAN-Card is an Intel card with 2100b chipset.
Anyone encountereda similar Problem? Anyone with a solution for this?
Thanks for your help!

Dan,
It sounds like one of your preferences has changed.
Go to preferences > audio > general, and make sure "track mute/solo" is set to "CPU saving (slow response)". It is probably set to "Fast " at the moment.
This setting (fast) basically causes immediate muting from the channel strip while your song is in play. This is because the audio is still being read from the hard drive, but the channel strip is simply muted.... like a hardware mixer. When set to "CPU saving", the audio from that track, when muted, is actually stopped from streaming from the hard drive, but there is a couple second delay before the audio is actually muted.
One would think that the fast setting is generally preferable, except when you need to do what you are doing. The only way to keep duplicate copies of channel strips acting independent of one another is to leave this setting on the "CPU saving" setting.
Hope that helps

Audio Stuttering When Importing Video

Hey guys, quick question.
I am currently working on a project that was given to me in the form of one Mini-DV tape. I'm trying to capture the footage into Premiere CS3, however, both as I'm capturing and while I'm watching the captured footage, there is a ton of audio stuttering, rendering the clips worthless.
I'm capturing using a Canon Ultura A mini-dv cam. When I listen to the audio coming from the camera's speakers, it's perfect. Only on the computer do I have issues with it.
My computer's speed should not be a problem either, I'm running premiere on this:
Intel Core2Duo E6600 @ 2.4
2 GB DDR2-800 ram
MSI P6N Platinum Motherboard (This is where the firewire port is located)
Nvidia 8800 GTX Graphics card
Creative X-fi Soundcard.
Any ideas on potential fixes?

Interesting, I will have to try and find another firewire cable to see if that fixes the problem.
Any other capture programs you guys could recommend for me to check out?

Audio stutters when under CPU load, USB sound issue?

ACD 27" connected to a PC via displayport/mini displayport adapter. When playing music while doing CPU intensive tasks, the audio instantly stutters, cuts out, grumbles, etc. This suggest my PC is simply not powerful enough however that's not the case (specs below).
What i've determined.
1. This only happens when using the apple display for audio.
2. When speakers/headphones are plugged in to the motherboard, everything works great.
3. This happens with all audio applications. itunes, vlc, winamp, etc.
The display uses its built in USB cable for audio, right? I'm thinking it's gotta be some typ of driver issue for USB audio. However I've updated all drivers so I'm stumped there.
Specs:
Intel Core i5-2500K @ 4.6GHz (65-70* under load)
CORSAIR CWCH60 Hydro Series H60 High Performance Liquid CPU Cooler
GIGABYTE GA-Z68MA-D2H-B3
G.SKILL Ripjaws X Series 16GB (4 x 4GB) DDR3 1600
Kingston HyperX SH100S3B/120G 2.5" 120GB SATA III SSD
SAPPHIRE 100326L Radeon HD 6670 1GB 128-bit GDDR5
Apple 27" LED Cinema Display (via displayport)
Thanks for any help!

Audio stutters when listening to music on U410

I have a U410 ultrabook (purchased in Nov. 2012) which has been working fine until a couple weeks ago. Almost any time I try to listen to music now (either online with internet radio or locally with mp3s), the sound will stutter and skip. This happens about once a minute.
I haven't installed any new software or changed drivers lately, but the computer does seem to be slowing down a bit compared to when it was brand new.
Has anyone else experienced this problem or have any ideas on fixes?
Solved!

Audio Stuttering When Music Score is Inserted

I created my first video using Premiere Elements 12 & was pleased with the results. YAY!!! I deleted all the existing audio and used Audio | Drag & Drop to insert Spin followed by Afternoon Sun. Worked great, saved the file & uploaded to YouTube. I then realized that I wanted to add two additional clips totaling less than 10 seconds. My first mistake was in not saving the file under a new name immediately (DOH!), but I digress. New video clips added to Project Assets panel, inserted into Timeline & trimmed a tad. No problem. I then tried to expand the audio to include the new clips. Realized one couldn't simply make the tune longer to accommodate the additions so I deleted the audio completely & added the audio scores as though starting fresh. The audio / music score skipped every few seconds with no discernible pattern, say, always at the beginning of a new clip. I made sure that I had clicked on Render, but that didn't smooth out the silent gaps in the music. Even the preview of the two musical scores stuttered intermittently so I thought the files must have somehow become corrupted.
I saved the file under a new name, exited the program, uninstalled, then reinstalled Premiere from the DVD. After all that, the previews STILL stutter. I've lost an entire afternoon trying to add those two brief clips. I can see the cursor flicker during the preview, but can't figure out how to correct the issue. I have closed down every other program & re-booted and it would seem that my 8GB of RAM should be sufficient plus it worked before, even with Photoshop Elements & Chrome open. Since the audio files are downloaded, I thought a slow download speed might be at fault. I ran a SpeedTest showing my download speed is 12 Mbps. I've had Premiere 10 on my computer for ages & never used it, but upgraded to 12 specifically to have access to royalty-free music & now that feature isn't working. As a newbie, I'm probably missing something obvious. PLEASE HELP before I resort to violence against my poor computer.
Thanks!
Victoria

I forgot to mention that my mp3 files play fine so this isn't an issue with my speakers. Further, I get the stuttering / gaps in other music scores I've not even downloaded while using the Music Score preview feature.

Video/audio Stuttering on Macbook 13

Hi All
I have a mid 2007 Macbook 13 running OS X Lion 10.7.4. all up to date. Initially I had 4G's of ram ( I know it only reads 3 ) now I have it running on only 2.
Problem is video/audio stuttering when running movies. mostly netflix and or connected to a flat screen tv. on wireless or wired connection. but it also happens just running youtube videos or videos that I have on the system mostly in .AVI format. I could be running movies with VLC or quicktime and same ting. I've tried turning every running program off. like firewall, little snitch, sophos AV, etc. after turning them all off I do a restart. I have done permssion repair, checked the disk, run the daily scripts, even downgraded to SL to see if Lion was too much for the system and nothing. of of the 4G's of ram that I have. I swapped them to see if maybe one or 2 of them ware bad. when I install the operating system, I do a clean install. delete partition, format, the whole thing and bring it up to date. not all at one time. disk permissions repaired after each big updated. almost half the time the videos will run ok and than it starts stuttering. when is doing it. not even the mouse responds in those few seconds. is like something is grabbing all the system memory for a few seconds at a time. it has gotten to the point that the system completly frezzes and I get that black translusent window that says the system needs to be restarted.
I have about 40% free HD space.
Any ideas ?
Thanks

Welcome to Apple Support Communities.
The behavior you mention is typical of MacBooks with the GMA 950 video chipset and 64MB VRAM.
The best solution I've found is to quickly pause the video and let the video load completely before watching, IF the website allows it and will preload the content. Not all of them do. Some sites automatically buffer before they begin playing.
Watch in a window rather than full-screen.
Watch content on your MacBook screen rather than a HDTV.
The Safari Extension "ClickToFlash" lets you choose whether to load Flash content at all. It also allows 'preferring' H264/HTML5 web video content when available, and seems to be a bit better than simply defaulting to Flash content for every website.
I have a mid-2007 MacBook 2,1 with 4/3GB RAM. It is the very oldest model capable of supporting Lion. After reading of performance issues with these older systems in these forums, I chose to remain on Snow Leopard rather than upgrading to Lion. Snow Leopard runs most things I do very well in 3GB. Lion really seems to need 4GB and would like 8GB, from what I read here.
You don't mention how fast your internet connection is. A faster internet connection MIGHT help some. A wired Ethernet connection MIGHT offer a bit more throughput than WiFi. Worth trying out, especially if you have a friend with a faster connection where you can try before you pay to upgrade.
Ultimately we're talking about 5-year-old computers. That's "ancient" in computer life cycles, and the best solution (not most cost-effective) is a new(er) Mac. It's not a problem unique to Mac. Old Windows XP systems lack the performance of new hardware running 64-bit Windows 7.
New or recent Refurbs with 4GB or more RAM, faster video chipset, more VRAM, faster clock-speed, Intel "Sandy Bridge" (or "Ivy Bridge" likely coming soon) dual-core or quad-core processor, and, yes, a hefty pricetag to match. Anything else is at best a temporary measure to buy a bit of time (a year, maybe?) until you can purchase a new(er) faster better Mac.

Audio stuttering in all browsers

I am having a constant issue with audio stuttering when playing videos, which has persisted for a couple of weeks now. This occurs in Firefox, Chrome and Internet Explorer.
I have tried downgrading to previous versions of Flash (including both 10.3 and a previous 11.X version), and (unless I am not doing this correctly) this has not fixed the issue.
I have even attempted to solve the problem by resetting Firefox, and then upgrading to the latest 15.0 beta, but this did not work as well.
Is there anything else I can do to resolve this issue, or is there something more fundamental broken with my machine? (I ask this as I have had problems with both Windows Update and a virus recently, and before these issues I did not have any problems with Flash playback.)
I am running Windows 7 on a Lenevo G570 laptop. I am currently using the latest version of Flash (11.3.300.268), and before I upgraded to the Firefox 15.0 beta I was using Firefox 14.1. (I believe that both Chrome and Internet Explorer are up to date, but I predominantly don't use these browsers.)

AirPlay audio stutters - only works when mirroring

I have a 3G Apple TV, which I use to stream audio content from my iPhone 5 and 3rd generation iPad. When I try to stream audio from those devices via AirPlay, it stutters horribly. If I enable mirroring, it works fine. If I enable mirroring for a second and then disable it, it also works fine. So, everytime I need to stream audio, I have to turn on mirroring and then turn it back off again - quite a pain. Has anyone else experienced this? Any ideas on how to fix it? I have read numerous articles on optimizing my WiFi network and router/AppleTV placement, and have optimized all aspects of the network as best I can. AppleTV shows a strong signal and has no problems streaming content using the AppleTV menu itself (Netflix, iTunes, iTunes Match, etc).

I also am having trouble with AirPlay on Apple TV 2 (iMac on 10.7, iPhone/iPad on iOS 5). I found a workaround using the Apple TV: turn AirPlay off/on, then go into the password screen and immediately exit (i.e., don't set a password). After exiting the password screen AirPlay begins playing.
I hope Apple recognizes this as a bug and fixes it soon.

[X121e] Audio glitch/stuttering when multitasking

Hello,
I am encountering some regular issues (glitches, stuttering) when playing some music and doing some operations in parallel (copy, browsing, etc.).
The discourageing things being:
- Latest driver/bios are installed,
- Occurs even when the laptop is powered by AC supply (i.e. maximum performance mode),
- The hard drive is SSD (no bottleneck here),
- 8 GB RAM (used at most @20%),
- CPU activity is quite quiet during these paralllel operations.

Stream7 - bluetooth audio streaming goes off when i turn the display off!

I have a hp stream 7 that is connected via bluetooth to my loudspeakers.
Everything is fine until the display turns off or i press the power butten to turn off the display.
When i turn on the display(press power button) the sound starts and play normally.
I can't find any option to turn off this behaviour in w8.1. Can you help?

The microsoft music player that is on the tiles metro section of windows supports music playback when the connected standby is activated. Unfortunatly if you are looking to go any further than this you will need to change over all your power control settings to that of a laptop.

IDT HD Audio stuttering 3d apps/games/tf2 - Windows 7 x64 - Pavilion dv7-4113tx

As per the rules I need to state:
I am a HP employee, my views/opinions/etc are my own and do not represent those of HP.
This is cross-posted from freezes/lockups.
I would file some sort of bug report - but I wouldn't know where to start, I don't work in an area that has anything to do with manufacturing HP products; and this is my free time now and I don't have intranet access .
I recently picked up a HP Pavilion dv7-4113tx Entertainment Notebook PC [ XV780PA ] for my personal use and overall it's been pretty good. It comes with windows 7 Home Premium x64 bit.
there is however an issue that I must bring up in regard to gaming, or i would assume any intensive 3d application, most notably Valve games, my test of choice is Team Fortress 2.
The game will work fine in native resolution - I get around 100-120fps but about every 30 seconds - 2 minutes, there is a audio/video stutter (by stutter, it will repeat the last .5 seconds of audio about 3-4 times in a loop while the screen will freeze on where the first audio stutter started), which will cause the game to 'freeze' for approximately 2 seconds and then continue where you left off.
Team fortress 2 is an incredibly time critical multiplayer online game, and this delay essentially means my e-death on multiple occasions.
I initially thought it was the graphics card, or the drivers - I upgraded the drivers to the latest on the ATI site, that increased my fps, but the stuttering was still there. After searching around on the internet a bit, i found a suggestion to disable the audio driver (device manager lists it as - IDT High Definition Audio CODEC) as a test - so I did so.
The game purrs like a kitten - absolutely no stuttering. my score went up immediately
So, my next step was to try and get some Updated Drivers for the IDT Audio device (note, i cannot find a model name anywhere in the hp specs - or on the internet really) - I found out IDT themselves cannot release drivers, that these can only be obtained through OEMs.
which brings me to here.
now - the closest I have found to the drivers I required are here: IDT High-Definition (HD) Audio Driver for Microsoft Windows 7
Note: - it says on the page that they are 32 bit drivers - but I've found they work with the 64 bit version of windows.
these worked a little better - it fixed another annoying issue - the fact if you use the volume controls in a fullscreen application that it will switch back to the desktop to display the on screen slider bar of the volume going down (which was arguably redundant as windows 7 displays the speaker volume in the bottom right hand corner) - and it just turns the audio down as intended.
however - the stuttering is still very noticeably present .
I then tried to use the HP Support assistant to run automated diagnostics and troubleshoot... which then downloaded the old drivers that gave me that fullscreen volume control issue back again - so i assume the original drivers.
So I installed the other drivers again.
My next test will be to use an external USB or firewire soundcard to see if this will allow me have games with sound.
Can an appropriate agent at HP please address this concern and notify when this bug will be fixed - IDT says they work with OEM's to fix issues regularly on the IDT link above.
I believe this is such an issue that will likely require a bug fix.

Audio stuttering problems with certain exported MP4 files

I'm currently running Captivate 6.1.0.319 on my old and decrepit Pentium 4 machine that has 4GB of RAM and is running Windows 7 SP1. I'm developing an online training course on RoboHelp 10 for Udemy, and they require all lecture files to be in MP4 format. Unfortunately, some of the MP4 files I generate from Captivate have audio stuttering starting a few seconds into the generated video and nothing I try fixes the problem.
All the videos are being recorded with video dimensions of 1360 x 978 pixels. I import the .cptc file I recorded into the .cptx file, and then I import an MP4 audio file into the .cptx file. When I finish editing the .cptx file, I publish it to an MP4 file using the highest video settings and the highest variable bitrate audio settings.
I have tried the following to try to fix the problem:
Turned off SWF compression.
Created a new .cptx file and copied the slide from the problem .cptx file into the new one, and published that new .cptx file.
Disabled all software operating in the foreground and the background.
Tried generating the MP4 file on my laptop; the laptop runs the same version of Captivate on Windows 8.
As I said, Captivate generates some MP4 files perfectly without any stuttering, and others have the stuttering problem. If this problem sounds familiar, it's because I wrote a couple of messages about this a few months ago and despite some good suggestions, I wasn't able to solve the problem. I've spent my time during the past few months trying to find another program that will convert SWF files to one of the formats Udemy supports -- MP4, MOV, or FLV -- without success. Captivate exports to SWF and HTML5 format files without any trouble at all. But MP4 generation is spotty and I need to get this resolved so I can get this project off my plate and start making money off it.
If you have any further questions, please let me know. I look forward to hearing your suggestions.
Thanks,
Eric Butow

Hi,
I am having the same issue and cannot figure out what is causing it, as it occurs randomly - but fairly frequently - when I publish to mp4. And it is not tied to the project - seems to be something happening during the publishing. The issue might occur one time when pubishing a project and if republished again it may or may not occur again. I would be very interested in finding exactly what is causing this and any step that are tested and proven for getting away from the problem.

Why is it that it would take a very long time [if ever] to change or adjust the tempo of a loop in the audio track when i set it to adjust regions to locators? Until now the spinning wheel of death is still very much spinning. thanks for any help.
Is there another way to adjust tempo of loops the faster way, any other technique?

No clue why the final processes have suddenly started to take so long. Two things I'd try: a) capture from an older tape to see if some problem with the new tape is at fault. And b) check the health of your RAM and the hard drive.
The red frame sounds a bit like a glitch we used to have in OnLocation (actually in its predecessor HDV Rack) which was caused by a partial GOP. But that was a product of HDV Rack recording from the live video stream. It turned out that HDV cameras intentionally interrupt the data stream for an instant upon starting to record--specifically to avoid recording a partial GOP to tape. So my gut says that the tape has partial GOPs at the points where you stopped/started recording.
