Buzz In Audio When Using DVI Output

I've had this problem for a while now, but everytime I plug in a monitor to the DVI port I get a horrible buzz out of my audio interface. I've tried everything: using different DVI cables and audio cables, using different audio interfaces, disconnecting everything except the necessary things, etc. and no matter what, the buzz comes when I plug something into the DVI port. I'm assuming that this has to do with the video card, I'm just wondering if anyone else has had problems like this.

Are the TV and the Mac plugged into different wall outlets in the room? It could be they are on widely different circuits, considering the wiring behind the wall, and that stray currents are flowing through the signal cables and upsetting the signals carried on those cables.
If the above is true, try plugging the TV into the same outlet as the Mac and see if things improve.

HT201177 no audio when using a mini display port to HDMI cable to TV on my Macbook pro

no audio when using a mini display port to HDMI cable to TV on my Macbook pro. can only see the video

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.

How can i detach the video from a clip so i can only use the audio when using imovie?

how can i detach the video from a clip so i can only use the audio when using imovie?

First, go to iMovie/Preferences and enable the Advanced Tools.
Import the video clip into an iMovie Event. When you get ready to use it in an iMovie Project, select the clip in the Event and drag & drop it on top of a video or photo clip in the project at the place where you want it to begin. When the pop-up menu appears, choose Audio Only.

How do you turn off Flash audio when using captivate Nav bar?

Hi Guys and Girls
I have an imported flash file that plays an audio track,
I have no problem turning the audio off, when the user uses
the button within the flash file to go to the next slide in the
captivate movie...
on(release){
stopAllSounds();
_root.rdcmndNextSlide = 1;
BUT if the user decides to use the navigation bar within the
captivate movie it all goes pair shape.. The flash audio continues
to play into the next slide. Anyone have a know how to solve this
problem?
How do you tell flash to stop playing the audio when using
the captivate navigation bar?
(The flash file is a flip book and the audio NEEDS to stay
within the flash file)
Cheers
Aquil0

Thank you! Thank you! Thank you! This totally solved my issue. I had a Captivate 4 movie using an embeded animation that had audio. It would play the audio again when the next slide appeared. I have to use Captivate 4, because my audience still uses Flash 7 (yikes). However, if you have Captivate 5 and are having this problem there is a widget that solves this issue: http://blogs.adobe.com/captivate/2010/11/animations-%E2%80%93-audio-sync-issue.html#commen t-3872

Hi Funkd,
The video / audio team is still hard at work trying to fix the audio problems introduced in 11.3. Would you be willing to test a build of Flash Player that contains a few changes and additional debug logging functionality? If so, please contact me directly at [email protected]

No audio when using FaceTime on iPhone.

No audio when using FaceTime on iPhone. The video works, but just static is heard during call. I have attempted multiple calls to another iphone and my mac. Should I send the phone in for repair?

Hi Anne-Lill Holme,
Thanks for visiting Apple Support Communities.
If you are not being heard during FaceTime calls on your iPhone 6, I recommend starting with these troubleshooting tips:
Restart your device.
If using FaceTime over a Wi-Fi network, go to the steps to resolve Wi-Fi network issues.
From:
iOS: Troubleshooting FaceTime
Next, I recommend testing your iPhone 6 microphone in other applications, such as Voice Memos.
If you cannot be heard on recordings in other apps, see this article for additional troubleshooting help:
If your voice is too faint or sounds unclear using iPhone, or iPod touch

How to sync/edit audio when using frame freeze or time remapping?

how to sync/edit audio when using frame freeze or time remapping? in premiere pro cs6

You need to give more information about what you want to happen to the audio when you freeze or time remap the associated video.
Is it synch video?
Is it music?
Is it Voice?
Generally .. you have to cut and design the audio around the video effect.

Has anyone experienced the loss of audio when using Apple TV when it has been working fine?

I can't get any audio through my reciever when using Apple TV. It's been working fine until a week ago. I've check my reciever, unplug the TV, and Apple TV as described but nothing. I switch to my Direct TV input and I can get audio when not using ATV. I've tried most everything I've read on blogs but nothing. One of those "pull your hair out" issues. Any direction would be appreciated. Thanks, Vince

Hi there Vfall!
I have some information for you that can help you troubleshoot this issue:
If you can see video but can't hear sound
If Apple TV is connected to a receiver, make sure the receiver is turned on.
Make sure the input setting you've selected on your receiver matches the input you have your audio cables connected to. See the documentation that came with your receiver for more information.
Make sure the volume on your TV or receiver is turned up and isn't muted.
Check whether you can hear sound while playing video only. Also, check whether you can hear audio feedback while clicking through menu options.
If you're connected to the HDMI port on your TV and Apple TV, make sure your TV supports audio through its HDMI port. The HDMI ports on some older TVs support only video.
If you are using HDMI audio, try disconnecting and reconnecting the HDMI cable.
If you're connected to the HDMI port on your TV and Apple TV, make sure your TV is setup to receive audio from HDMI. For some TV's this is automatic, but for others there is a choice between digital and analog (for HDMI audio, choose digital). Read more about HDMI audio.
Try the other audio outputs on Apple TV to see if they work.
If possible, try using different audio cables.

No Audio When using Video Out to Firewire

I do not get any audio when I use Firewire ntsc as my video out. When I set video out to canvas playback then I get audio. I want to use print to video but I cannot because the audio will not work with Firewire. I get the image on my external monitor but not the audio. I checked to make sure and the audio was not on the recorded dvd. I cannot not use print to video with canvas playback.
My Easy Setup is Format: NTSC, Use DV NTSC DV Converter. I tried using Firewire basic and got the same results.
Please Help
Ken

The audio does not play at all from the timeline if video out is set to Firewire. To answer your question, no the audio does not play in the external monitor when playing back from the timeline when Canvas is used as the video out. However, I don't believe the converter box is the problem. The audio would play in the internal speakers when using firewire as video out but it does not.

Samsung 205BW goes blank when using DVI

Hi
I have a G4 Mac Mini. I recently purchased a [url="http://komplett.ie/k/ki.asp?sku=322266"]Samsung 205BW 20in widescreen LCD monitor[/url].
I connected it via the DVI port on my mini with the DVI cable that came with the monitor and it seemed to work great but occasionally the screen will flick black as if there was nothing connected to it. It happens most noticeably when I go from a fullscreen quicktime video to the desktop or if I activate Expose. Also if the Mini goes to sleep and I try to wake it the screen stays black and I either have to reboot or change to using the VGA cable.
The monitor works perfectly if I use a DVI-VGA adaptor and connect to the VGA port on the monitor but I'd prefer to use DVI.....
I read on here of people using SwitchResX to change the settings for the monitor. I downloaded it but I don't really know what to input in the custom settings... perhaps someone here can help?
Here is the DDC file from SwitchResX:

I had the exact problem you report with my core duo Mac Mini connected to a Syncmaster 204B. This problem persisted when I returned the monitor several times to Samsung for replacement 204B's. They eventually upgraded me to a refurbished 204T and the problem disappeared.
It seems to me that Samsung has some real problems with screen blanking when their monitors are hooked by DVI to certain Macintoshes. For anyone contemplating a Samsung monitor, I'd recommend another brand until it's known that this screen blanking problem has been resolved with all Samsung models.

Call Pickup - Users experience One Way Audio when using Call Pickup Orbit to pickup internal calls with internal Lync 2010 Callers

Hi
Noticed an issue where when using Call Park Function with users you receive one way audio when answering the call
The scenario is
1) If a user is internal and is homed on Lync 2010 Pool and calls an internal user who is homed on a Lync 2013 Pool and another internal user homed on a Lync 2013 Pool picks up the call with Call Pick Up orbit, Lync 2010 users only hears one way audio and
same for user who has picked up call
2) If the scenario is an External PSTN call or another Lync 2013 user these calls are fine
In Lync Tracing logs a SIP/2.0 481 Call Leg/Transaction Does Not Exist error is returned
Is this a known bug or expected behavior - Call Pickup is basically useless until all users are migrated to Lync 2013 as there is no way of a user knowing whether call is internal or external and if the user is on Lync 2010 or 2013, obviously in my
large organization 2000 users no an overnight thing
Coupled with the fact no Team Call Group\ Simultaneous Ring can be in place for Call Pickup to work im thinking Call Pick Up is not going to happen for awhile
Is there any fixes\ developments that may help this issue or is there a setting I am missing

Hi,
Please install latest update for Lync Server 2010 and 2013.
http://technet.microsoft.com/en-us/lync/dn146015.aspx
If the issue persists, please enable logging tool on Front end and Mediation server to get trace for troubleshooting.

No Audio when using firewire DV

Hello!
When I set SoundTrack to play the video using my firewire DV device (a little camcorder attached to an analog TV set) it reroutes all audio to that camcorder instead of using my otherwise fully functional 5.1 audio setup.
How can I keep the audio playing through my external (USB) 5.1 audio setup while routing the video to an external firewire MiniDV camcorder?

I've had a similar problem and posted a few questions myself regarding the "no audio" when going from FCP to STP.
But I figured it out: If you connect a DV cam via Firewire, the audio in STP is routed to the camera only.
In my case I also have a MOTU 828MKII audio interface connected via a separate FireWire, but it seems that in STP only the DV cam get the audio.
As soon as I disconnect the DV cam, the Audio can be routed to my audio interface as per my Audio/Midi setup.
In FCP I don't have this problem.
So now, when using STP, I disconnect the DV Cam and get my Video via an RGB connection to the TV and the audio can be routed as I want.
Not really elegant (and not really Apple-like not to have full Audio/Midi setup compatibility) but then again, when working in STP, it's the sound that matters and not the picture.

No audio when using headphones.

Has anyone had issues when using headphones with the android maxx?

On every devices iPod etc. Usually it's the head phones and not the device it self. Try swapping them out. Wow after participating in Apple support forums for years. I have to feel bad for how bad Verizon is trashed! They, Verizon are a great carrier and the post I read are ridiculous! Verizon likely replaces more devices, simply because people don't understand the hardware or software.
