Audio glitch after OS X (10.5.3), Quicktime (7.5), & Airport Utlty update?

I just installed these updates and restarted.
I went to Front Row to watch a movie and there was no sound. I checked the music files and they were fine as well as the sound for TV Shows. I then got out of Front Row and went to watch the same movie through Quicktime (the movie is in my Movie folder). Again, there was no sound.
I checked out a bunch of movies in the same folder and still no sound. I am able to play the movies with sound through the DivX player though.
Any ideas?
TIA, Jo

one of the things this update was supposed to fix was audio problems related to the last airport update and os update. looks like they didnt fix anything but broke more...
if it was me, my first step would be to tun airport of then try to watch the movie. also make sure your audio in system preferences is set to built in.
good luck!

Audio glitches after BIOS update on GD65 Gaming

I updated from the beta 1.94 BIOS to 1.A0 and since then have experienced audio glitches. Streaming videos the audio will fast stutter periodically. My DJ controller also glitches which is a different soundcard entirely. Using DPC Latency tool I see large random spikes every so often which coincides with the audio glitches. I tried LatencyMon and it shows HDAudBus.sys as causing high interrupt to process latency. But if I disable that it then gives the same fo ACPI.sys. If I kill some services and background tasks it would sometimes show the same but for hal.dll or wfd0100.sys (part of Logitech Setpoint I think). I can never seem to nail it down. So I booted into diagnostic startup using msconfig and the spikes more or less went away. So I ended up booting with just the essential network and audio drivers running using msconfig and it seemed to fix it but I cannot be doing that each time I want to use my DJ controller or play a Youtube video.
It did not do this before the BIOS firmware upgrade.
Ideas?
Win7 Ultimate 64 btw.
EDIT: I flashed using LiveUpdate and forgot to do a BIOS reset with power cord disconnected (going to try the latter now now but doubtful it will help). Should I re-flash from USB?

There are a good number of GD65 Gaming mainboards, so it would be helpful to know exactly which chipset you have. M-Flash has been reliable with Z87 and Z97, but if that method is used, be sure to select the BIOS + ME option. Install the newest ME driver after a flash.
It's the Z87 Haswell version.
BTW there is a dual BIOS on this board right? Can't I switch to the other BIOS, bootup and test? Never tried the dual BIOS thingi before and wondered about if it's possible to switch between them? EDIT: Just read the manual. Not what I thought it did. Oh well.
EDIT2: I flashed the latest beta 1.10 B3 BIOS using the USB boot method, reset the CMOS by crossing the pins and uninstalled/installed the latest ME driver.
No difference.
If U run LatencyMon 'as is' after reboot and after stuff has settled down it reports random spikes of the HDAudBus.sys well over 1000ms
If I disable HDAudBus.sys in system devices it then spikes with ACPI.sys
If I use a tool like JetBoost to kill some apps and services spikes with usbport.sys or ACPI.sys or HAL.dll or sometimes wfd0100.sys
If I use msconfig to boot into diagnostic mode I don't get any spikes.
If I use msconfig to boot into a mode where only the services required for network and audio to work I also get no spikes (but this is tiresome to use. I wish msconfig had user profiles. I also tried a tool called Startup Selector which promised that functionality but it crashes when I apply the changes).
I can only surmise a MS service (tried just disabling non-MS services with no effect) or combination of MS services is causing this issue.
I'm thinking the next step is an in place upgrade of Win7 and if that does not fix it a complete reinstall (that would really suck). :(

Blu-Ray 5.1 DD SS Audio Glitch after import into Encore.

Working on burning a full length blu-ray with two audio track options (stereo audio, 5.1 DD SS) I'm not having any problems connecting menu's or burning. After the initial burn everything was working flawlessly except when I played the video with the 5.1 DD track I noticed the audio would glitch at certain parts. The glitch sounds like a CD skipping (i.e the speaker would say Bubble and it would sound like Bu-Bu-Bubble) the audio doesn't go out of sync when this happens, it's small and the video keeps playing but it's still noticeable and an issue.
Both audio tracks are one complete track, no cuts or seperate clips. The 5.1 track is .ac3. The stereo track is mixed from the 5.1 track and doesn't have the glitch at all. I've gone back and checked the source audio and haven't noticed any transients or spikes at the places where it glitches. The problem occurs when I pull it into encore. Even before burning the audio will error inside the timeline preview. I'm not transcoding the audio or video at all as I have manually compressed the video already. Everything is perfect except for this glitch and I'm all out of ideas of what Encore is doing to the audio to create the skipping glitch any thoughts or ideas would be great. Hope i've given enough information. I'm new to the forum so please let me know if i've left anything out or missed any etiquette.
My system:
Encore CS4
FCP 7
Mac Pro 2 x 2.93 GHz Quad-Core Intel Xeon
12 GB Ram
10.6.6 OSX

Most likely he used Apple's Compressor, Bill - the system specs state FCP7 is being used.
Bitrate is a valid question though.....this should be no higher than 640kbps (and IMHO certainly no lower - DD sucks at the best of times)
Sorry for the long reply back guys. We had the audio work for this project outsourced so I had to await details to your questions. The bitrate is 457.67 kbps so the bit rate shouldn't be causing the issue. The audio was completely pre mixed in Pro Tools and they just sent us a ready to use .ac3 file. Hope this helps!
CAleb
Hey Caleb.
Thanks for the details -and that is probably your problem.
457.67kbps is nothing like DVD-Video compliant, and almost certainly not BluRay compliant either.
For BluRay, you should be using 448 or preferably 640kbps.
DVD uses either 448 or 384kbps Dolby Digital, and the figure you are giving is extremely odd, looking almost like a VBR encoding which DD should never, ever be. Using 384 gives you unidirectional content above 10kHz (IE, mono) and 448 gets it all the way up to around 14 or 15kHz before it goes unidirectional. In all frankness, there is no good reason at all to use Dolby Digital as it sucks - badly - and all BluRay players are required to decode at the very least DTS Core Audio (1536kbps) which is fully discrete all the way to 20kHz.
I think whoever you outsourced this to got the DD encoding wrong - simples!

Why do I get audio glitches after pausing songs?

I have an iPhone 4 running on the latest version of iOS and I have been getting an irritating popping noise on some songs if they are paused after the songs starts, i.e. the first 5 to 10 seconds, then resumed without me skipping to another song.
This is a problem I am concerned about as when his happens my iPhone seems to remember the exact point where i paused the particular track and insert this popping sound so that everytime I play the track when listening to a previous track in a album or playlist I hear the sound.
The only way I can eliminate the problem temporarily is to tap back to restart the track sometimes a few attempts are required to get the song to play cleanly again.
Has anyone else had this problem with this version of the iPhone or any model or since the recent updates?
I am worried that I am going to ruin my music collection, what happens when I sync to my iTunes?
My only option at the minute is to try hard to remember not to pause songs at the start and then play them from where i paused it.
Also should I try to reformat my iPhone and then resync my music to see if this removes the glitches from the songs?
So far it's only affected a few songs but I'm worried it could become a serious problem in the future considering I care about the quality of my songs and one song in particular was bought from iTunes!
Can anyone suggest any other advice to preserve my collection from this rather annoying glitch in my playback?

Have you tried restarting or resetting the iPad?
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Does this happen all the time and no matter where you are using the iPad?

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.

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.

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.

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.

Hard drive glitches after battery replacement... normal?

Hello, I have a 4Gen 20gig ipod with click wheel and I just replaced the battery myself last night.
I then plugged it into my computer to sync and it was recognized by windows, but not by iTunes, the hard drive would whir, then click and then try again, then stop. I figured it was just that the battery wasn't charged enough yet, so I let it charge overnight.
In the morning it synced fine. I was then playing it in the car, and some songs would appear, then the hard drive would whir, click a couple of times, then skip on to the next one. After a couple songs it started playing them normal. After skipping a few and the hard drive spun to load more music into the temporary memory, it would whir, click and then skip the song, then whir click and skip that one too... and it kept doing it. Then I reset it, and it kept showing the apple symbol, then the Exclamation and folder icon, then tried restarting again. After trying to reset itself 4 or 5 times, it finally succeeded.
I read a few threads on here, gave the ipod a gentle nudge on the right hand corner a few times, and now its playing and I haven't had any symptoms yet for about an hour.
Is this normal for a hard drive on an iPod to glitch after a battery replacement? I had no such problems when I had the other battery in it, so it's hard to believe that the hard drive is going bad exactly at the same time I changed batteries. It is the right battery for the right iPod, anyone else experience this or have any words of wisdom or comfort?

Pretty fast and non-stop, even when I'm not working. Could it be dirty? Is there a way to clean it?
Does the Apple store charge just to look at something?
Even if the noise was a dirty hard drive you can't clean the innards of one. You cannot even open one. Well you can, once.

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 Glitch in Adobe Premiere Pro CS5 Timeline (not a clip problem - it's the timeline space)

I have an audio glitch that appears to be tied to a space in my timeline and not to a certain audio clip. If I drag or move the audio clip further up or down the timeline it plays fine. If I move a different audio file into this area, the audio drops out in the same area, even with volumes set where they need to be. There are absolutely no keyframes set in this area and I want to be clear about that. However, this issue did come up only the software froze on me as I was loading my project. I believe my best bet is to delete delete my media cach and media cache files so that clips are reconformed... unless someone has additional input or has experienced similar issue with the sound.
As a note, I also reinstalled Quicktime. I am working with AVI files/aac auio codec.

No. You will not find any Master Track Keyframes. These will be on the Audio Track, and will be attached to the Track, regardless of what Clip you have there. Here is a look at Track Keyframes, not to be confused with Clip Keyframes from PrPro 2.0:
Hope that this helps and good luck,

Lost audio files after saving.

I lost my audio files after saving in Logic X and now my project file has the extension .logicx on it and my audio files are nowhere to be seen. I made some changes to the project, moved the file to another folder, then they asked if I wanted to replace the other file with the new and I said yes not thinking that it would matter. Is there any way that my audio files are still out there somewhere? And no I don't have time machine hooked up.
Thanks.

if you replaced that file.. then you have lost it's contents as they have all been replaced with the one you copied over... and as you have no backups you cannot, as they say.. un-scramble the egg...
Finally start making backups as soon as possible...
As the old saying goes...
"There are three things in life you can always count on.. Death.. Taxes...and you will need a backup of your computer data at some point"

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?

I am getting a buzz sound on my laptop whenever playing audio/video after 1 min.

i am getting a buzz sound on my laptop whenever playing audio/video after 1 min.

What model laptop is this? Does the issue occur when you use headphones? If you could give me some more details I will be able to give you some more suggestions to resolve the issue.
