[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.
By looking for reference on this forum, it seems that no valuable solution were found here: http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Lenovo-x121e-multitasking-performance-audio-st...
And here too: http://moinsound.wordpress.com/2011/12/27/the-nerdbook-part-2-first-impressions-of-the-thinkpad-x121... (look in the comments).

Ipad background audio from video when multitasking

Hello.
This is a request if people can either feedback On their present experience or try this out themselves first and feedback.
I have an ipad 1. When ever i try to get background audio to play from video when multitasking in another app, eg safari, from any video app including plex, airvideo, vlc, and the original apple video app. All that occurs is that the icon changes to the ipod and a random song is played from my music library instead of the audio from the video i was watching. This does not matter if the video file is streamed or stored on the ipad itself.
There is one slight and occasional proviso to this, as at times if the video file is tagged in itunes as 'music' rather than 'movie' or 'tv show' etc then it does on occasions work, and on occasions youtube videos will play in the background. But most of the time these aspects also dont function int he background with the ipod icon instantly replacing which ever video app icon i tried to use in the background.
Now my sons iphone 4 manages to function correctly and always plays video in the background when multitasking.
I have asked this question before on this forum, with no response, so booked a visit to my local genius bar. Where they checked my ipad and agreed it wasnt working as ios should, then interestingly they attempted to do the same on an ipad 2 and it failed to work in exactly the same way. Their response was that this was obviously a fault of the ipad ios, possibly due to the ipad having a separate video app where as the iphone has video within its generic ipod app.
I did the usual by informing apple via of this bug through the feedback system, and requested that the genius bar do the same. But having thought about this, and failed to see any other users on this forum who are also puzzled at this lack of what i think is an important function, i wonder if this means that i am the only one who likes to listen to video when im browsing, so dont need it, or wether everyone elses ipads function as ios should do, and for some reason both my ipad, and the ipad 2 tested in the shop are at fault.
So can i request if others reading this can have a go to see if their ipad will play background audio from video when multitasking, or if the same problem occurs.
Thanks very much this is really appreciated.

Oops clicked the wrong button, I meant to click a 'helpful answer' as it hard to have a correct answer to such a question.
But thanks for the replies.
It looks like this is a bug in ios solely for the ipad, as it does work fine on the iphone although wonder which way the ipod touch will perform. interestingly it looks like i may also be in the minority of wishing to listen to video files as I browse:)
Which probably means apple may never get around to sorting it, as no one else uses the function.
Anyway thanks for the replies, if any one else wants to see the bug have a go and comment, i find it funny how I seem to be the only one to have found it to date.

Audio Disruption / Skipping When Multitasking

Hello. I occasionally DJ over the internet. I have been saving my bucks to buy a MacBook Pro and update the 3 year old technology from my Powerbook. I have noticed that when I am playing music locally on my new MBP, the audio occasionally "skips" when I change windows. My PB did not have this issue and I am upset that the newer faster computer is. It seems like it is having a hard time multitasking.
Also, when I run the program "Second Life" my entire system freezes up. I have found forums on the Second Life website talking about Apple having river issues with the graphics card, but that they have yet to address it. Apparently WoW has the same issue. This is SO frustrating. I feel like my PB was the super computer now.

I had FIOS TV installed yesterday and had this exact problem today. Called tech support and they suggested it was a splitter or loose connection and they set up a service appointment.
After the call I checked all connections and all was fine. Figuring that all the IP related content (i.e., multi-room dvr) passes through the router, I did a remote reboot and everything is now fine (no more skipping on HD content).

Audio Glitch in Apple DVD player when at the end of a story

Hi Could anyone shine a light on why when I build and open up my dvd project in Apple dvd player there is an audio glitch. But on the original mpeg there is no audio glitch there. I have chapter markered my project in fcp. I have ten storys and one chapter in each story.
when played on a dvd player the glitches are not heard
Any help on this matter would be great.
sam

in Apple dvd player there is an audio glitch. But on the original mpeg there is no audio glitch there.
when played on a dvd player the glitches are not heard
Have you played the DVD with more than one player without hearing glitches? What, exactly is the glitch? A click? In any case what you report suggests that there is a problem with Apple's DVD Player.
Do you hear the glitch when you play the DVD (the physical disk) with Apple's DVD Player?
I seem to be having a similar problem, but I haven't burned a disk and used a DVD player to play it. See this thread: http://discussions.apple.com/thread.jspa?threadID=1863240&tstart=0
DVDSP shows my soundtrack file to be longer than what it actually is. Is that the case in your situation?

Quicktime audio playing up when I multitask

Hey guys,
When I use quicktime to listen to lectures and stuff I usually have it on full scree and I multitask with other programs running such as safari, word and finder etc. When I switch from quicktime to another program (either using command + tab, or swiping on my trackpad) the audio glitches. A few times it's just paused for a quick moment as if i've muted the sound, then continues playing. Lately it's been getting worse, and it makes a static noise, or it just doesnt play the audio at all, but the video is still playing.
Anyone know how to fix this?
Thanks

Sorry Ralph,
It didn't solve the problem.
What's happens is when I go onto a coca cola site I enter my email and password. The process shows it is working and nothing happens, just keeps on trying.
When I logged into my internet provider to delete my emails nothing comes up. Had to use another galaxy tablet which worked, no problems..
Next I enter completions where you have multy choice answer and you pick one and same with the rest of the question and all the iPad does is revert back to the in completed form.
Sorry it is so long winded I've got the latest updates on my iPad Air tried resetting it, cleaned out the cookies etc.
Thanks

Audio Glitches on Timeline, but not when played in QT?

I had a client send me his project on a harddrive.
They exported a .mov file from FCP and it has no audio glitches when played with Quicktime.
But if i drag that file to a timeline and watch it through my DSR-25 to a NTSC monitor, it has audio glitches in certain spots.
Always at that spot though and if i watch the file in Quicktime, it plays fine.
All audio was exported originally out of FCP using Quicktime Movie with 48khz, 16 bit stereo so nothing needed to be rendered.
Seems like it has something to do with it going over via firewire through my DSR-25.
Has anyone else had this problem.
I can't make a Master DVCam tape for this master because of these audio glitches.
Thanks for any help,
Brian

I read a post about a user having this same sort of issue.
He said when he turns off his video layer, in my case just V1, the audio played fine.
Same with mine.
So it seems to be an issue with the video track playing with the audio track.
If i export it and bring it back in, will it just create that same audio glitch?
Guess i will have to try.
Anyone have this issue or similiar?
Thanks,
Brian

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 glitches when music stops

Hi there,
I'm the happy owner of a Lumia 800.
The only point that ennoys me is an issue I have with audio. I checked the long thread dedicated to the poor audio in this forum, but I don't think it is the same issue.
Actually, audio is good when music is playing, but when music stops (eg pausing a song on spotify), I hear some "glitches" for 1 second, then silence comes.
I'm running 07.10.08107.03 (latest fw available in Belgium).
Thanks for any feedback.

Windows 10 Audio Glitching

So my wife's HP laptop has upgraded to Windows 10 and everything seems to be great except for audio playback. Reference: By audio glitching, I mean that the sound stutters and slurs with digital-sounding artifacts. The sound doesn't stop outright, but sounds similar to when a CD plays over a scratched section.Laptop: HP Pavilion dv7-6c21nrOS: Microsoft Windows 10 Home (64-bit) She noticed the glitching immediately as she listens to quite a bit of music. We thought it was Spotify at first, but subsequent testing with YouTube and then testing the sound in the control panel gave us the same glitching. It seems to happen at the same positions in songs, regardless of where you source the audio, though the severeity of the glitching varies. CPU Load: We checked CPU load by opening up the Task Manager and sorting processes by CPU while playing music. CPU load was normal. Drivers: We tried using the generic High Definition Audio drivers as well as the IDT drivers that installed with Windows 10, the ones for Windows 8.1 and the ones for Windows 7. I even tried installing the Microsoft HD Audio Tool, as suggested in other posts. Settings: We found that playing with the playback quality seemed to help a little, especially if we cranked it up. It didn't get rid of the issue entirely though. Changing the device exclusivity and priority had no change. Other Solutions: We did a restore of Windows 10 hoping that it was just some left-over issues, but that made no difference. With the IDT drivers, we tried enabling and disbaling various options in the Beats control panel without any change in the glitching. Any help would be appreciated. My wife is ready to see how far the laptop will fly...

After doing even more searching, I came across the LatencyMon tool and ran that. What I found was that, like other people, ndis.sys was not behaving well. We disabled both RealTek network devices and found that the audio problems went away, though this is not the solution we desired. Luckily I had a LevelOne WiFi adapter, which plugged in and ran just fine. No issues, no latency, no sound glitches. Conclusion: Your RealTek network device drivers need to be fixed and updated. I haven't tried using previous versions yet, as the adapter I have works.

Serious audio glitch problem in 9.1.1 - please help!

Got a problem with audio glitching that is driving me insane - hopefully someone can help (please! :_))
I'm on Logic 9.1.1 on a recent MacPro using 10.5.8, 12Gb memory. I've created an arrangement in Logic with two multi timbral / multi-output instruments (Kontakt and Stylus RMX - both up to date versions) with aux outputs for all of the instruments channels; 16 in the case of Kontakt, 8 in the case of RMX.
I'll work with this setup and after a while I find that whenever I play and then press stop, a tiny portion of audio will repeat rapidly, over and over again in the 'master' left output channel at +6.0dB - it also shows up on all the instrument auxes at a much lower level. It's as if Aphex Twin has invaded my Mac... Weirdly, this problem crops up even if I'm not outputting anything from the multi-instruments - it's enough that say, an EXS instrument, plays something, I'll press stop, and then the glitch signal will appear in all the level meters of the multi instruments and master output, but not on the EXS level meter. If I press play again, the glitch disappears and audio playback is perfect - it only happens when stop is pressed. And no sign of it if there's a silent part in the arrangement with no tracks playing anything.
If I have any instances of reverb on bus channels, that audio will will also feed into the left channel of those busses, even when there are no channel strips sending to them. Weird as ****, and driving me up the wall with frustration.
I've omitted it being down to my audio interface (Metric Halo 2882) as the problem persists if I switch to the Mac internal I/O.
I'm trying to work through this at the mo as I've got a deadline for 2pm this afternoon - but I'm worried I might not make it due to throwing my feckin computer out the window. Please help - thanks!

If your deadline wasn't looming, I'd say buss everything to a stereo track and record this stuff. It sounds great, you could use it in another project later...
But to your problem: The only quick solution I can think of for you to try is to create a brand new fresh project and use the selective track import feature to bring your tracks into the new project. Don't start from an old template (that you may still be using since Logic 8 or something) because this could indeed be the root of the problem. Build a new template from Logic 9.1.1, then make a new project from that and import all your tracks. If it's your project that's corrupted somehow, this could be the trick to solve it, and it won't take too long to try, so it's worth a shot.
I'm not sure of this, but something is telling me I've seen this problem before, and if so it was on Leopard (not Snow Leopard) on a MacPro in the studio. Have never had it on my personal MBP (which was only ever Tiger and then Snow Leopard - I skipped Leopard on purpose because the studio machines seemed so very dicey). Also, I don't use RMX on my own machine but in the studio, yes. Same deal for multiple output instruments, I rarely do that either. On that point, another thing you could try is to forget about multiple outs for now, and just work with stereo instances. Yes I realize this will mess up your entire painstakingly built-up mix.. but if this is causing the flakiness you may have no choice but to go back to stereo instances, finish your writing, then do the whole mute/solo thing to bounce your individual parts to audio and proceed from there. In this scenario, selective track import will be a timesaver too because once you've done all the bouncing, you can just create a new project and import all of your channel strips and so on, to then re-assign the individually bounced tracks to the assignments you had before. Will be quicker to recreate your mix than having to do it from scratch. Or you might not even need to do this step because if eliminating the multi-out instruments makes the prob go away, then you can just recreate your assignments within the same project using the bounced audio tracks.
Get to it.
Once you've delivered.. I'd open that project again and record all of that lovely Aphex Twin messiness for later use.

Movie audio becomes corrupted when exported to iDVD

Hi,
I have created a movie that is 53" long in iMovie, added various transitions, text screens, music tracks and photos but also kept a lot of the camcorder audio as well. The movie plays perfect in preview on iMovie but when I have shared it with iDVD some of the audio and voices are out of sync and there are also some random loud noises, a quarter/half a second long, that appear at certain points in the iDVD version - they sound like bits of the actual iMovie audio but from completely different part of the movie.
So, the problem is that the movie is perfect in iMovie but when shared with either iDVD or Media Browser, there is some loss of syncing and these random noise bursts.....
This is the same when I have burned the movie to a DVD and played back through the DVD player - the out of sync and noises still appear.
Any thoughts on how I can get around this to have a perfect DVD as well - dont really want to get everyone around the Mac to watch the movie later this month!!!!
Thanks

There is a known audio glitch in iMovie '09 that appears in exported movies when custom speed settings have been used in the project.
It's important when making speed changes to use only the preset speed percentages shown on the speed slider. These are: 12.5%, 25%, 50%, 100%, 200%, 400% and 800%. Don't manually type in your own custom speeds that differ from the presets.
The glitch that you describe appears only in the exported movie, and as you have noted, is not evident in preview (before sharing). The fix is to revisit your project and adjust any custom speeds to the presets. This can be a pain of course, as you may have to resynchronise the project elements.

MPEG Streamclip Audio Glitch

Hi, I've been using MPEG Streamclip without any problems... until recently. Has anyone else experiened audio dropping out or glitching when exporting mov's from VOB's?
The audio keeps dropping out in the same place, even when I run MPEG streamclip on a different G5. Playing back the DVD, the audio is fine, it's only when you listen to the mov that you hear the glitches.
Is this a common error? If so, what can do the job of MPEG Streamclip, without the nonsense with the audio glitching?

Well, not if the DVD plays back fine with no glitches. It's only the mov from MPEG Streamclip that has audio issues. I also used Drop2DV on the same VOB and the audio came out fine, however the lack of control in exporting makes me want to figure out what is wrong with MPEG Streamclip.

X-Fi Xtreme Audio [Windows 7] Random Audio Glitches

Hi I have Windows 7 and a PCI X-Fi Xtreme Audio sound card. (Not PCI-E). My problem is I get random audio glitches when listening to music or playing a game. No card I have had before had this problem. My computer is fast enough and I have the latest Windows 7 X-Fi Xtreme Audio driver installed. So what might be causing this?

#Did this happen right after you install the sound card new or did this happen out of the blue?
Sorry I don't have any further suggestion at this point, you might want to contact Customer Support to see how they can help you further.

Audio glitches at the start of video

Hello,
i have a few audio glitches at the start of the video.
This happens only at the start of the video, at the first 30-40 sec, where there is a music soundtrack.
I am using encore 2.0 and a portable HP Pavilion dv4000.
The video was coming from a dv tape that was captured with windows movie maker as avi and imported as avi to encore.
But the sound was changed to 48 khz, at the edit (Avid).
Please i need your help.

Neil,
Thanks for the response. I started looking for Audioblack in the New Asset list, the Transitions and Effects, all through Audition, manuals, Internet, everything, and about all that I found was reference to an indie band - "Audioblack," or comments attributed to you. I have a lot of material from Dolby, from when I first began using 5.1 Surround in DVDs, but did not see this term there. It was probably in some of their more technical papers, and not the "primer" course ones, that I already had. You very clearly pointed out *what* the problem was likely to be, but I wanted clarification as to the exact solution. You cleared that up beautifully.
Based on one of your earlier replies along these lines, I instituted a 2 sec. gap in my Audio Tracks at the beginning of all Timelines, as part of my workflow - 2 sec. Black Video, Dip to Black to 1st Title, and silence on my Audio Track, but was becoming worried, that I needed to create an actual Audio Clip with certain properties. I see that my interpretation of Audioblack works.
I had not encountered the problems, that some others had, but then my test DVD players are all higher-end Marantz units, and who knows what a client is likely to try and play the DVDs on? I wanted to establish a workflow, that would give me the greatest chance of success, regardless of the hardware. Thanks to you, and to others, I am honing my workflow, as well as I can.
I think, based on some other responses, that involve hardware, that I will dig up a very old, and cheap Panasonic DVD from my gym, to use as a test machine - doesn't get much older, or cheaper, than that.
Greatly appreciated,
Hunt
PS I still use an older Cambridge as the rear-channel amp out of my Carver C-400 pre. Great unit and still going strong!

Fix found: Broadcom drivers, Firewire audio and audio glitches

Hi,
I've been working with MOTU (Mark of the Unicorn) trying to get my 828mk3 firewire audio device to work properly under Vista 64-bit in Boot camp (note I had same problems with 32-bit version).
The problem was that I would get audio glitches in the form of beeps from my audio device every 30s-1:30s. Each glitch would last about 1s (@10000Hz). After many tests, I discovered when I disabled the Broadcom driver (latest MacBookPro5,1 distributed version), the problem went away.
Does anyone know why a Wifi adapter could affect a Firewire 400 device? Note I had the same problem with my old MacBook3,1.. so the problem is not related to the new MBP.
Anyways, I hope someone fixes the Broadcom driver; never-the-less, if you have this problem, this is your solution
Thank you,
Michael

No sound with Vista Ultimate on iMac.
