Audio levels on an external monitor vary during playback when using HDMI audio

I've been having issues with movie playback using a large 1080p HDMI TV. During playback the audio level will come in strong, go faint, then go strong again, but not on any sort of pattern I could discern. It did this on three seperate movies legally purchased via iTunes. I get audio and video without trouble, its just the audio goes soft when it shouldn't.
If you remember the VHS days and "MACROVISION" encoding, then you have an idea what it was doing, although it was the audio levels, not the video playback.
Is this a fault of the system, a DRM gremlin, or something else?

I think you may be onto something with the graphics card concept. The problem I am having only exists when I am working on an HD project. When I switched back to DV-NTSC then the monitor is fine during playback.
Yes, I am routing my external monitor through my DV deck, which is not an HD deck - so again, that could be another weak link in the chain.
This is the first HD project that I am editing, so obviously a few kinks still need to be worked out. My internal hard drive has 1.5 gigs of ram but I am not sure what the specs are on the graphics card.

External monitor--Freeze during playback, transition issues

I am utilizing an external monitor for playback. Every now and then the video freezes and audio continues. Also, even after performing a render all option, cross dissolves skip periodically during viewing referenced movie. When I compress the movie, I have no problems.
Please help!

AFAIK, (I came in around FCP3) It has always been recommended that the operation of the FCP system is divided amoung at least two disks. Each version of FCP is placing higher and higher demands on the system. That you have gotten away with this for so long is truly amazing. You must live right!
There is really nothing all that new and innovative about the iMac with regards to video editing. In fact, it is a poor platform. It does not allow the installation of a second internal SATA drive, it has no expansion slots to add either a second Firewire or SATA bus, you can not upgrade the video card and so on.
Recommended distribution of the FCP elements over two disks -
Drive 1: OSX, FCP application files, FCP Project file (no media files), thumbnail and waveform cache.
Drive 2: capture scratch, autosave vault, audio + video renders +all other media files
With a good external firewire 400/800 drive (not usb), you can get multiple realtime streams.
And no, partitioning the internal drive does nothing good for you. the same heads have to scan over an even wider area after you partition. The effect can be to decrease read/write speed.
good luck.

External monitor frozen during playback

I am having trouble with my monitor not PLAYING during playback. I get an image when I scroll through the timeline but when I play - the image is frozen.. As soon as playback stops, the monitor refreshes to the correct frame - but it doesn't show during playback.
We have tried all these steps already:
1) Make sure that the camera/deck is connected and powered on BEFORE you open FCP.
2) In the Final Cut Pro menu select AUDIO/VIDEO Preferences and make sure your signal is being sent out thru Firewire DV.
3) Go to the menu and select VIEW>EXTERNAL>ALL FRAMES.
4) Click in the % box above the image and select FIT TO WINDOW.
5) Go to VIEW->refresh A/V devices
6) Make sure the Log & Capture window is closed
7 ) If you want it to play in both the canvas and the external monitor you need to go to the FINAL CUT PRO menu and select AUDIO/VIDIO settings and make sure MIRROR ON DESKTOP is selected under the PLAYBACK OUTPUT section.
What is really mindboggling is that the monitor is working in terms of giving us the correct image - just not during playback.
PLease help - thanks.

Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

How can I get audio to play from my TV when using hdmi cable? Video looks great, just no sound.

How can I get audio to play from my TV when using hdmi cable? Video looks great, just no sound.
I've tried plugging the hdmi into the TV directly and the receiver.
I get video every time. HBO to Go , Xfinity, ABC, Youtube, etc...
just no audio. Any suggestions?
I've tried starting the apps then plugging in the hdmi cable.
I never tried this before I upgraded to IOS 5.

Claudiamil-
I had not tried it with mine since upgrading to iOS 5, so I just did. I'm using a small Vizio HDTV. I did not try YouTube, but did try several videos and musical numbers. In all cases there was sound, including stereo when the source had it.
I assume you are getting sound from the iPad when the adapter is not connected, so the volume is not turned down. Dah*veed's suggestion to reset may be what you need.

Can I use external speakers with the iPad when using Facetime?

Can I use external speakers with the iPad when using Facetime? How do I do that?

They have to be either plugged in via headphone jack or the dock port at the bottom. If you can. I've used it on apple tv, but that's it. I don't know if the others work, but I don't see why not. Try plugging in speakers in the headphone jack. You will get an answer :)

Viewer and External Monitor doesn't playback at same time

When watching clips in the viewer window, they playback fine. But on my external monitor, it only shows the first frame from when it's played. when I stop playback, the external monitor then shows the last frame the Viewer window is stopped on. How can I fix it so that the viewer and external monitor playback the clip at the same time?
At the moment we're digitizing footage with the Offline RT Photo JPEG codec set to 75% quality.
A few days ago we were digitizing footage at 35% quality and that footage plays back fine. We moved to 75% quality at the editor's request. A few days ago we had created a few sample 75% quality tests for the editor to view. I loaded those clips into Final Cut right now and they playback fine as well. So it's all of a sudden just these new clips created yesterday :S.

Yes.
Forgot to mention that the timeline plays all the footage back properly on both the canvas window and the external monitor. Sorry for not mentioning that sooner.
More discoveries! The playback 'freeze' only happens if I open a clip from the browser into the viewer. If I open a clip from the timeline into the viewer, it plays-back fine!

External monitor works only works when laptop screen displays

Hi there, I just connected a different (newer, but not brand new) external monitor to my T61. When I toggle screens (fn-f7) the external display gets no signal in the 'external display only' position, but displays beautifully in the 'both' position. This never happened with my old monitor. I would like to use the external display and not have the laptop screen display. Any ideas? Many thanks, Ellen

Try this:
After connecting external monitor, press win key+p and thrn choose projector only.

T400 Win7/64 Advanced Dock -- External Monitor No Longer Comes When Booting

My configuration:
T400 (2767-14U)
Windows 7 64bit
256MB ATI Radeon 3470HD (switchable graphics running in "High Performance")
Advanced Dock (2503)
Lenovo D221 Monitor (using VGA cable)
I used the above configuration without issues for a year.
My problem:
I just replaced my hard drive, clean installed the OS and all applications, and updated all drivers and the BIOS using System Update. Since doing that, my external monitor no longer comes on when I boot my computer in the dock (lid closed). The only way I can get the external monitor to work is to boot my computer first, and then "hot dock" it.
As far as I know, all of my BIOS/Power/Graphics settings are the same as always.
Thanks in advance for any help!
Solved!

Maybe the BIOS setting for Default Display got switched back to ThinkPad LCD?

Can the B520 be used as an external monitor for a macbook via the HDMI in?

Hi,
I'm very happy with the Lenovo, but it looks like our family will be acquiring a macbook in the near future. Can I use HDMI in on the Lenovo B520 so that it becomes an external display for an apple computer?
Thanks for the help.

Thank you very much for the help. Now if I could only figure out why the Lenovo B520 doesn't see my apple airport extreme network anymore. I guess I'll have to post separately for that one. It was incredibly fast and now it doesn't connect at all. Thanks for the help on this. I need a mac for access to iBooks Author. Silly (and expensive), but true. Thanks again!

Audio sputters and then completely cuts out during playback

Hello, everyone. I've been editing in iMovie for years, and have never come across this problem until today.
When playing back a clip that I've inserted into my project, the audio sputters on and off for about 10 seconds, and then cuts out completely. If I stop playing, and then start again, the audio comes back, but in about 10 seconds, sputters and cuts out once again. When I play back the original clip that I imported, this does not happen. It is only when it is actually in my project. The audio waves shown below the video are all intact as well.
I've already tried restarting the computer and deleting the iMovie preference file to see if that would make a difference, but it has not. Any ideas as to what this could be, or even better yet, how to fix it?
Thanks for your time.

Update: When detaching the audio, this problem goes away. However, the audio fade-ins from transitions, etc. go away. Is there any way to solve this problem without detaching?

Audio playback delay using M-Audio Audiophile

I have an MBP, 2.66 GHz i7, 4GB 1067 Mhz DDR3 Ram. External monitor on DVI. OS X 10.6.8
I've just started using FCP X and have cut one movie with it ( http://youtu.be/SUQLTk4aCS8 )
However I am now experiencing a problem that audio playback is about 10 frames behind the video, even though the waveform on the screen lines up with the video.
I am using an M-Audio Audiophile firewire audio interface to playback audio. When I switch back to the internal soundcard audio sync is fine. This problem started after I updated the M-Audio driver, as the one on the MBP was the one that transferred across when I copied all my files from my previous MBP (I can't remember Apple's name for this process, when you connect the new computer to old computer by firewire and transfer all files and settings automatically)
The M-Audio control panel wasn't working on this MBP so I updated to the newset driver, the 64 bit version. I assume the i7 and OS X 10.6.8 is 64 bit but I am not positive as I could not find any guidance on my computer or elsewhere.
Can anyone help me with this? I prefer the sound quality of my Audiophile, I find the internal soundcard very trebly. Just want to get rid of the playback delay.

Thanks for responding.
It seems quite strange that the driver update caused the problem...maybe I should roll back to the previous driver? worth a try I guess...although this is a new machine so doing that could cause other problems.
ANNNNOYING....on the internal soundcard, whenever I click the mouse or scroll the timeline I hear annoying clicks and pops thru my speakers.
What kind of 'pro' software doesnt let u use an external soundcard. I think Apple really screwed up here. I feel sorry for everyone who invested in full-on FCP suites and training time for editing feature films who are no longer going to get updates and support.

Using smart previews on iMac to control two sets of identical original files on two external drives --- render previews setting when using smart previews

I’m just getting started with Lightroom and if someone can help me I’ll be very appreciative.
I’m using an iMac with a 1TB drive and two external 2.5 TB drives for backup. My active files are on all three drives and I’m running out of room on the iMac drive.
With the smart previews capability of Lightroom 5, I’m hoping to remove all the active files from the iMac drive. I hope to import existing images into the LR catalog from two identical drives with identical folders and have both sets of images reflect the changes I make using smart previews on my iMac.
I just created two identical test folders of junk images on the external drives and was following a beginners tutorial on importing. However, I see nothing about using smart previews on my iMac that, when connected, will update more than one external drive at the same time.
I’m also wondering if, when using smart previews, it matters how I set the render previews during the import process.
Many thanks for any help,
Karl Hentz

I don't see any way to use smart previews to update both external drives at the same time. The smart previews are linked to a specific set of images. But it seems to me that if both drives are in fact identical, once the catalog is updated when one of those drives is connected those changes should also apply to the files on the other drive. It's actually the catalog that gets updated, not the images. Smart previews and regular import previews are completely unrelated. How you have your import previews configured will have no effect on your smart previews.
Incidentally, in order for my suggestion to work it would be necessary to only have one of those external drives connected. And when the other EHD is connected it would have to have the same drive letter or name. In other words it would have to appear to the iMac that it is precisely the same drive.

Time Machine fails to backup HD and stalls computer when backing up to external HD (Western Digital WD5000MT) when using Firewire 800 but works fine using USB

I have a mid 2012 MBP (MacbookPro9,1) running Mountain Lion 10.8.2. When I start a Time Machine backup to an external Western Digital HD (WD5000MT) connected using a Firewire 800 cable, my open programs stop responding and in general my computer freezes up not allowing me to open activity monitor or the console utility. I can't even shut down or restart my computer and must hard boot to reset. Though removing the firewire cable that goes to the external HD can sometimes get my system working again. However, the WD external HD also has a usb port and when I connect it to my computer via a USB cable, Time Machine seems to backup my system fine without stalling my computer. This same external HD worked fine with Firewire 800 using my old late 2007 MBP running snow leopard. I should note that my brother has the exact same model WD external HD and he also had issues with the firewire port on his MBP running mountain lion. I have run the disk utility checking for disk/file permission errors and the drive itself seems fine. I initially formatted that drive as ExFAT but while troubleshooting reformatted to HFS+ and still had the same issue. I tested using a different firewire 800 cable but still had the same issue. Can't think of anything else to do. I don't have another firewire-compatible device to test if it is the HD vs the firewire port. I would prefer to use the firewire port for quicker transfer speeds but I'm stuck with USB for now. Any suggestions?

Feedback when using an Audio Interface

Hello! I recently recorded some music with friends of mine. I am using an audio interface which I have a Mic and a guitar plugged into. So on the recording they sound crystal clear. Due to the fact the interface has only two lines in (MONO) I can not set up another mic for the drums. So I used the aggregate device through the MIDI and on garageband i record with the interface and the built in mic. Where I am encountering a problem is for the built in mic recording, it is also picking up the mic and guitar through the amp. I can't figure out how to filter it pre-recording, or take it away post-recording. Any help would be greatly appreciated!
-Kevin C

The mic will record everything it hears, no amount of filtering is going help much. If you already have a clean guitar and vocal track just delete the drum track and just record a new drum track using the Mic and interface. Make sure the drummer uses headphones to monitor the playback
