Monitoring HDV through Decklink with Firewire Audio Monitoring - Latency

A question for all you pro's out there...
I am currently using Final Cut Studio on a Mac Pro with a Decklink HD Extreme card for monitoring video and a M-Audio Firewire 410 for audio monitoring. My output settings in FCP are having the Decklink for video viewing on a HD Monitor, and Using the firewire 410 for a multichannel audio output. I seem to be having a sync issue with the video and audio not in sync. Does anyone know how I might can correct this sync issue?
What is everyone doing for Multichannel sound?
Any ideas?
Thanks for any help!
Bob

Did you capture threw the BM Decklink? You might have an issue with sync if you did. If you used firewire then its an adjustment I sure. I'm sure there must be a control panel for the BM Decklink. If you can't find it take two asprins call Black Magic in the morning.
Good Luck

Internal computer noise with firewire audio devices

Hello
I have a Power Mac G5 PPC 2.3 and Mac Os X 10.5.6, with tiger I have the same problem too, I bougnt my Mac for audio work, and from the purchase day, I have the same problem, I bought my first audio sound card, M-Audio Firewire 1814, and I installed the last drivers for my operating system, when I start Logic I must go to prefferences audio and select the device, I select coreaudio tab and M-Audio Firewire 1814, and when I click on apply changes, in the Mac start an internal noise, low level, and hign frecuency, and this sound keep while logic is open or another audio aplication with M-Audio 1814 is selected like audio device like Pro Tools M-Powered.
Aplications work fine but this noise I think is a conflict with audio device drivers, I can hear this sound too when I go Aplications/Utilities/Audio Midi Setup/ and in the audio devices tab the internal noise not is sounding but when I click on Midi devices tab, the internal noise start and is sounding while Audio Midi Setup is Open, if I quit Audio Midi Setup the noise stop.
In the Activity monitor I can read MIDI Server process is launched when I click on MIDI Tab, and if I select and close this process the noise stop.
It is only for the noise when is sounding with audio midi setup, close MIDI Server and noise stop, but when the noise is with any application (Logic or Pro Tools) in the activity monitor quit MIDI Server process but the noise keep sounding.
I have Digi 003 Rack and Pro Tools LE too, and I have the same problem when Pro Tools LE start.
If I select M-Audio 1814 in system prefferences/Audio, like audio device and open ITunes the noise is not sounding with ITunes, I can listen music whithout problems, but If I select Digi 003 Rack like Audio Device in
System Prefferences/Audio The noise is sounding with ITunes start becouse Digi Core Audio Driver is launched.
I think is a conflict between Thirty Parts Drivers and The System but I need help, what can I do to resolve this.
Thanks

Nope, someone elsewhere suggested a thing called "ground loop" occurring. Meaning, the interference from the electric current. They suggested trying it with battery power (power detached), and without. But at least for me, made no difference unfortunately.

Playing DVDs in 5.1 With Firewire Audio Interface Connected for Logic Pro

This is exactly the same q as asked by plantwebguy in July 06, link
http://discussions.apple.com/message.jspa?messageID=2696970#2696970...
I'm struggling to get an answer on this anywhere... I have Logic Pro running 5.1 Surround Mixes on a g5, using a Metric Halo Mobile IO Firewire audio interface - its 6 analog outs are connected to a M Audio LX4 powered surround system. It all works great - until... the problem is when I need to listen to DVDs with 5.1 soundtracks (for reference), or even HD trailers (with 5.1 soundtracks). With the Mobile IO selected as audio interface, DVDs only play in stereo. I think this is because the 5.1 soundtrack is only output thru the optical out - but connecting the optical out to the Mobile IO and selecting 'Digital out' on the g5 brings silence.. Im told this is because the MIO's optical in wont decode 5.1. I'm interested to hear from anyone with a Pro Audio interface - like a MOTU etc - who needs to switch between mixing their own music in 5.1 and then listening to DVDs in 5.1.. I cant be the first, surely?
Plantwebguy said he solved his issue with VLC. Do we know if VLC willl decode 5.1 and then output it to the Interface via Firewire? I've searched the net for a Pro Audio interface with (1) 6 analog outs & mic inputs etc (2) firewire connection and (3) optical in that reads AC3/5.1 etc (rather than just ADAT).... nada. Sorry to be long-winded but I cant get a solution anywhere..
Thanks in advance

IMac20" with firewire audio-interface konnekt24D by tcelectronic

Hi folks,
I've got some cryptic problems with my iMac and the connected firewire audio-interface (konnekt24D by tcelectronic). I'm running MacOSX 10.4.10. The problem is that after four days working with no occuring problems I got no sound output. When I restarted the Mac the blue firewire light of the audio-interface disappeared and the tcnear control panel says 'no device'. I decided to update the firmware and then everything runs properly for one day. The next day I got the same 'no output' problem. I decided to update the firmware again but now the blue firewire light disappears and I got 'no device' message from the tcnear control panel. I started the Mac again but the interface was still gone. Now I switched off the Mac and turned it on again. The interface was there and I had output. Next day I got the same problems.
The tcelectronic support said that I should disconnect any other network cables, enable every network setting on the network control panel and connect the power supply of the audio interface. I did everything but got no improvements. The people from tcelectronic concluded that my audio-interface could be defective. So I went to my mönger and he gave me a new one.
From now on everything worked fine for three days. During this time I changed nothing on my setup. No new software was installed, the only thing I did was to start LogicExpress 7.2.1 and begin with my work. After three days I got the same 'no output' problem again. Now I think that there must be something wrong with the iMac. It is the 'old' version (bought in May this year) and I don't know exactly what to do now.
What I don't understand is that both devices worked a few days and then the problems occured. As I said before I didn't changed anything, installed no new software, etc. Maybe the harddisk of the iMac is defective? I've plugged the audio-interface into the other firewire port of the Mac but got no improvement.
I don't know exactly what I should do know because I worked ten years with a PowerMac/Audiomedia III/SCSI system and never had such strange problems.
Greetings to all of you,
Dorsch.

It appears that sp3 has issues with firewire. I'm seeking a solution too, short of reinstalling as this person suggests. See also his link re: the famous little patch. I tried that already to no avail. I'm using SP3 too. My firewire behaves like USB... which would/could cause issues like you're describing.

Problem with FireWire audio interface (Edirol FA-66)

I am experiencing the following problem with my FireWire Audio interface via Edirol FA-66. At unpredictible moments the 'Digital In' LED starts blinking, and after that the audio signal stops working. I do not know if Logic is the culprit, since it also happens now and then with iTunes
Note: there are digital in/outs connected.
Only shutting down the Edirol and restarting the iMac G5 resolves the problem, be it only temporary: after a while the phenomenon shows up again.
Extremely ennoying.
What could be the culprit?

Hi Patrick, I don't know that specific interface but could it possibly be that the flashing LED also act as an alert for when the firewire connection has gone down?
Reason I suggest this is I have the same thing from with my iMac & focusrite saffire Le, where i lose audio now & then, & when it happens if i check in the interfaces software control panel it always has a 'firewire connection error' - I then just have to unplug & replug-in the interface to re-establish the firewire conection. Just a thought but maybe it's worth consulting the edirol manual/tech support to see if this is the case ref the LED function?

No sound effects with firewire audio device

I use an external (firewire) sound device for better sound. When I'm in a call, the audio output is routed correctly to that device. But, sound fx, such as when someone sends me an IM or when someone is calling are NOT routed to that device. If I unplug the firewire device, I do hear the sound fx through my macbook speakers. So, if skype is on my side monitor it's very easy for me to miss IMs and calls because I don't hear the sounds. This makes me look very unprofessional to my colleagues. Basically anyone who uses a mac for professional audio/video is going to have an external audio device. Please fix this bug!

Audio Output with firewire audio interface issue

Hi, i have a quick question that maybe someone here can answer for me. I originally posted this in the OS X forum but someone recommended that I may get better help here.
I have a PowerPC G5 with Mac OS X 10.4.11. I do a lot of home recording and use a Presonus Firebox Firewire recording box. I recently picked up some new monitor speakers that I run the outputs of my Firebox to and I use the Firebox as my output sound device in my system preferences.
Everything works pretty well unless I touch one of the volume buttons on my keyboard (which I tend to do out of habit pretty often). If I do press one of the buttons the volume dips way down and I have to pump my speakers and firebox volume up all the way up to hear them. If I do this, and then happen to put my computer to sleep when I awake the computer the volume is now at an extremely high level until of course I press one of the volume buttons on the keyboard.
The big problem is I have twice in the first two days of having my new speakers turned them way up and later in the day awoke my computer from sleep mode and had itunes or a dvd BLAST out of my speakers at a ridiculous volume.
My question would be is there some way in os x I can disable the volume buttons from being used if i am using a different output device? OR is there a better way for me to set my system up in my system preferences?
It was suggested in another forum that I look into the help for the Firebox unit instead of the mac so I have started to do this as well. I just thought that because everything works fine UNTIL I touch the computers keyboard it seems like the computer is making some drastic change in how the sound is being output, so I thought I'd try to find an answer here as well!
Thanks so much to anyone in advance who has any sort of help with sound preferences and or settings!!

This is a very good point! Thanks for your response.
I do realize that I have multiple volume controls going on here in a chain. First my computer, then the Firebox interface, then my speakers have volume knobs...
But what I am seeing is when I first press a volume key on my computer (even if it is the VOLUME UP key) there is drastic lowering in volume. Only until I put my computer to sleep, and awaken it does the volume return to a normal level.
It seems that when I am pressing the volume on my computer it is activating something on the mac's end... or changing the way the sound is being output.
Again all of this could be avoided by me not pressing those 3 keys on my keyboard... but old habits die hard! so if there was a way for my mac to give total control of sound output over to my firebox that would be best.
any more help is greatly appreciated!

Have PC connect to internet through Mac with firewire and file sharing

Hi, I have a network of 2 computers, one Mac and the another PC. The Mac is connected to the internet and the PC is connect to the Mac through firewire. I have managed to set up a file sharing system, both Mac and PC read each other without any third party applications. This is working great, however, the two computers successfully connect only when the PC is turned on first, or else the Mac will say that there is no device connected to the Firewire port. If the Mac is on, and then the PC gets turned on, I have to restart the Mac in order for the connection to be established. Is this normal? Is there a fix for this?
I'm also interested in having internet on the PC as well. How will I be able to do this through a firewire cable?
Thanks

Run System Preferences->Sharing->Inernet Sharing->Firewire
It's that simple.

On my imac27" with firewire audio card i have drop out and crackle when i push on airport.

Why???

this audio cards working perfectly and update

Have you tried to update or uninstall/reinstall the SDCard reader drivers? I've read that the uninstall/reinstall step will sometimes work on some problem devices.
You have run the AppleSoftwareUpdate while in Windows and the Mac side right? Sorry, had to ask.
Have you done a search on the 'net or Microsoft for the error (code 10)?
You can try to reload the BootCamp drivers again manually and see if that will work, but it may mess with your sound again. (or get it to work the first time?)

FCP Problem with Firewire output to external monitor and speaker ???Help

i have a g5 powermac. the problem is when using Final cut pro 4hd. when i output my work through firewire to my external monitor and speaker i have a problem with the audio signal. Theres feedback/noise/hiss from the speakers. The firewire connects to DSR-11 vtr deck which feeds my monitor and speakers. it only happens when in FCP is set to A/V firewire output. does not happen if Video output is not set to firewire.
I Diagnosis is that it is not my dsr-11 deck or firewire i've ruled those out. The problem is either FCP software or Hardware problem with my G5
Does anyone have a similar problem. please respone, i will try to answer any respones,
Thanks
powermac g5 powermac

CaptM
From the firewire that feeds the dsr-11. on the output, i use s-video cable to my monitor (sony pvm-14l) and High Quality rca cables thet feed the audio to the Roland Speakers.
I've changed all wires and still have audio problem. I,ve changed my Dsr-11 deck to my camcorder and still have the problem.
If any of u guys use FCP The problem happens When I select view> external Monitor > and select firewire for Audio/ and video. I have never changed my editing habits, something just went wrong with the signal, I think its a Hardware problem with the firewire connection. I'm Going to have to bring this to a Apple Service Center In my local area one day.

I have a Powerbook G4. I want to use an iMac desktop, the model that is shaped llike a lamp, as an external monitor. Can I do this with firewire or USB cable or do I have to have a different cable?

You need a network connection and a product such as ScreenRecycler. All such products require a bootable OS on the iMac.

Recommendation for external monitor with good audio?

I've got a MacBook Pro, about three years old or so. I also have a new iMac.
I'm happy with the audio on the iMac. Good enough that I don't need external speakers to listen to iTunes.
I have a weekend place and when I go, I only take my MacBook Pro with me ... and I miss the 21" screen and the better audio from my iMac.
Can anyone recommend a monitor for MacBook Pro that is just as good as the iMac, especially with regards to the sound?
Ideally under $300.

Any with built-in HDMI should work and 1080p. ViewSonic, NEC, Sony, LG, and Samsung. Viewsonic and NEC may also have color correction capabilities. Make sure your Mac is one of the ones with built-in audio over mini-Displayport or has Thunderbolt or HDMI to connect:

If it does not have audio, and is a mini-Displayport only, see this tip for alternatives:

I need to output a PAL HDV project from FCP as a PAL DV file with 4 audio t

I need to output a PAL HDV project from FCP as a PAL DV file with 4 audio tracks - specifically one stereo pair to be t1&t3, the other stereo pair to be t2&t4. This is the standard way requested by an international distributor of tv programmes. I understand how to set the sequence in FCP to output 4 audio tracks - either 2 stereo pairs (1&2, + 3&4), or 4 discrete tracks. But how do I then output this as a QT file?
The manual tells me that to export multiple audio tracks, File>Export>QT Movie has it's Config pop-up menu in the Audio Settings area of the General tab of the Sequence Settings. Well, that's set for 4 discrete channels, but the QT export settings only allow for 2 mono or 1 stereo output, and that's what I get when I try it. What it says in the manual just doesn't happen.
Exporting via Compressor, on the other hand, has an abundance of choices of 4-track outputs, none of which are labelled as anything resembling 'discrete'. Would any of those 4.0 settings suffice? Or am I likely to get myself into difficulties further down the line? As I am monitoring for this task on a 2-track audio system, I cannot confirm exactly what I am getting when I use any of those settings.
Any advice would be greatly appreciated!
John

Call me naive, but I've not heard of splitting the stereo pairs like this before.
What broadcaster? (perhaps one of our EU regulars will drop in...)
You can do all sorts of pairing but it is coincident tracks pairing- eg 1/2 + 3/4
Sorry I can't offer anything.

Imac late 2012 problems with motu ultralite mkIII through thunderbolt to firewire

first - hi @all users here in the forum.
i have a really curious problem with my audio configuration. at first i must say the audio-config. with my macbook pro (mid 2010) and my imac (early 2008) works fine without problems by using firewire.
but not on my imac (late 2012). there is a static, high frequently noise on my monitors. and i don't find the reason for that problem. i have delete alle the audio drivers and make a fresh install. reset the nvram and pram with holding the power key and so on. two weeks ago i have contacted apple care and send the imac to the next service provider. first i think for a defect power-supply. but the provider located only a defect ram. they change it and send me the imac back. but nothing has changed. if i heard about the defect ram from the provider i know this couldn't never ever the reason for that problem.
i hope anyone can help a little bit by this problem...thank you.
here is my hardware setup:
- imac late 2012,"27 3.2ghz core i5 processor, 8 gb ram, 1tb fusion drive (osx 10.8.5)
-> connected over the thunderbolt to firewire adapter to
- the motu ultralite mkiii
-> connected to the yamaha hs80 with balanced cables

the static, high frequently noise on the right is stronger than on the left.

Audio Interface: Mackie Onyx 1640 with Firewire - How good is it?

Hey,
I was about to buy a RME Fireface 800 as my Audio Interface, but then checking the Mackie HR824 Monitors (first i wanted to buy the Genelec 8030) i discovered the Onyx 1640 with Firewire, which of course is not a new product.
So, the dealer told me that the PreAmps and quality overall of the Onyx1640 is almost the same to the RME Fireface800, being the Fireface slightly superior.
Now the great thing is that IF the Onyx is that good, i could shot 2 ducks with the same bullet because with that Mixer/AudioInterface, besides using it for recordings, I could rehearsal with my band as well in my "studio"... and even record some jam sessions.
BUT the question is, how good is the Onys 1640 really in comparison to the e.g. RME Fireface 800 ??
Has anybody experience with the Onyx ?
For recording I would set a MindPrint MKII between the AudioInterface and Mic for voices.
Thanks in advance for your opinion/advice!
Cheers!

I cannot comment on the Onyx though I just wanted to let
you know that the FF800 can be used as a stand alone unit
and does not need a computer. You could set up a preset
to do any configuation you need for any situation. I have mine
in a mounted in a portable rack case. Of course paired with
MacBook Pro you would be a formidable portable solution.
