Random Audio Signal

I haven't seen anyone else with this particular issue on the forum yet and I dont know if this is specifically a Snow Leopard issue, but ever since I got my new 27" iMac a couple of weeks ago, a random audio signal seems to be creeping up and playing on my computer for no apparent reason. I have closed all applications in an attempt to kill it, but the signal continues to play. It comes in the form of various things, sometimes it sounds like an audio clip from a sports movie, or a rap and hip-hop radio station, or a short commercial, or an indy rock song. These alternate over the course of a few minutes, then the signal fades away only to return a few minutes later and start all over again. I hadn't heard it for a a week or so so I thought the issue had been resolved, but it returned last night and continued through this morning. I thought maybe I was picking up on someone else's bluetooth device signal and receiving whatever it was they were listening to at first, but if I attempted to make my computer "undiscoverable" Ill lose the ability to use my mouse and keyboard... Any one have an idea what could be going on and what I can do to fix it? Thanks!

I hadn't thought of moving the computer. The TV receiver is pretty close by I guess, but ironically, we don't get much reception through it. I have my PC set up right next to the iMac, and I used to use this work station the majority of the time with my MBP without ever picking up any kind of signal. Im pretty sure theres no radio station anywhere nearby, unless some kid is running one out of his bedroom next door or something. Interestingly, I haven't heard it since I first posted this, but Im anticipating its return any time... It doesn't bother me as much as it does my wife. It seems to happen when Im not around and she's working on the computer (conveniently), but its usually still going on when I get home. I was unaware of any radio receiver built into the computer, is there a way to turn it off, or temporarily disable it? Thanks everyone.

How to correct "An incompatible audio signal" with Apple TV and HD signal

I have an Apple tv2(mc572Ll/a) running version 4.4.4 of the software, connecting to an older Sharp Aquos LCD-26d6u TVvia a regular HDMI cable.
I used to be able to watch a rented movie until my onsitel technician/ teenager adjusted something.
Now when the preview plays the sound works. When a video is displayed using AirPlay from the iPhone the sound works.
But when the HD movie plays the message "an incompatible audio signal has been received. Check the output device settings" and there is no sound.
When I connect this to a newer HDTV the movie sound works.
Any suggestions on what Apple tv or tv settings to use to get the sound back (other than upgrading my technician/teenager/tv)?

Thanks! I changed the Dolby setting from On to Auto, and the sound started working for Netflix TV shows. Before I was getting the message:
     Incompatible audio format received check output device settings
and there was no sound.
The Settings are accessed through Apple TV.   When you have Apple TV on, and you see all the colored rectangles for Netflix, huluplus, HBO etc., (which can be accessed by repeatedly hitting the Menu button on the remote), the top row shows:
   Movies   TV Shows Music Computers Settings
Use the 4 way controller to choose Settings, then press the button in the center of the 4 way controller to select Settings. Then select Audio Video. Then scroll down to Dolby Digital. When you are on Dolby Digital and you push the button in the center of the 4 way controller, the setting will change. I changed the Dolby Digital setting to Auto.

Audio stereo signal split into 3 or 4 stereo audio signals (in one single clip)?

Hi,
facing massice transcoding issues when exporting a project I had to analyse the involved video/audioclips...
and found out that for some of the video clips the audio signals have been split into even 3 or 4 complementary stereo channels.
Note: Each channel contains just a part of the original signal. This is obviously due to cutting action ...
What can I do? I have no clue!
My question:
How to get one single stereo audio signal (2 channels) out of this mess?
Thanx big time,
Oliver

Assuming we're talking about shorter takes and not a longer, spanned clip, I don't think what you want can be done in PP. Nesting will always bring the audio over as one track.
You may have to skim the clip sequence in the Program Monitor and copy/paste the portions you want to use into a second sequence for output. This will preserve the audio.

Using video and audio signal from a camera connect...

Why is it not possible and is skype intending to implement the ability to use the video signal form a digital camcorder connected to a tv?
A lot of people these days have digital camcorders or digital cameras that produce video signal. Why can't those be supported as video input by skype?

Hi,
The following ports are at the back of your computer:
Figure 4: Back I/O panel
1 - USB 2.0: 4
2 - LAN
3 - DVI-D
4 - D-SUB port (VGA port)
5 - Audio: Line in
6 - Audio: Line out
7 - Audio: Microphone
You already mentioned DVI-HDMI : it works but no sound. That's true because DVI does not carry audio signals. All you need is using RCA cable to connect port #6 to your TV.
Regards.

Enabling Simultanious Analog and Digital Audio Signals

My apple TV runs through a Yamaha receiver. It is hooked up with component video and digital audio cables. I also need to hook analog audio to my receiver so it can play outdoor speakers through zone 2 (which only recognizes analog signals). Zone 2 does not work when I hook both digital and analog cables. Called Yamaha and they said to look for a setting on Apple TV that enables simultanious analog and digital audio signals. Does anyone know if/how this can be done? Or any other way to make the analog zone work without losing digital on the main zone?

AFAIK, the analog audio on the ATV outputs all the time. The audio output setting in the ATV just determines whether the digital output is Dolby or PCM. Try turning off Dolby in the ATV audio settings and see if that makes a difference. If not, the problem is probably elsewhere.

Can you tell me how to measure audio signal frequency in measurement studio with visual basic 6.0?

I'd like to measure two differential input signal(I.e. A+ and A-),below is two test projects,
1.connect A+/A- to PCI 6052E card's ACH0/ACH8 ,and refer to GND for testing
2.connect respectively A+/A- to PCI 6052E card's ACH0/ACH8 for testing
Could you tell me the details of the second project?and give me a illustration in measurement studio with visual basic 6. 0 about the second?
In addition,I would like to measure the audio signal frequency,could you give me a illustration in measurement studio with visual basic 6.0?
Wait for your reply!

Dear kelven,
Thank you for contacting National Instruments.
To address your question, there are Analog Input shipping examples that demonstrate how to measure an analog input differentially, as you specify in (2).
As for measuring the audio signal frequency, you may want to check out the following KnowledgeBase. The link is:
http://digital.ni.com/public.nsf/websearch/4b08380530d72d3b86256340004c3005
Let me know if you have any further questions or if this does not resolve your issue.
Thanks again and have a great day!

Apple TV 3 audio signal goes off after each song?

My Sony receiver has to reaquire the audio signal from the ATV 3 at the beginning of each song when streaming songs from the Mac. This causes a fraction of the beginning of each song to be missing. Very irritating. There is a clicking noise at the end of each song as the receiver loses the audio signal at the end of each song. Is there a way to work around this?

Hi iman911,
Welcome to Apple Support Communities.

Transfer audio signal to LINE-OUT connector

Hi all,
Is there any way to transfer the audio signal which is generated by means of a Built-in speaker on the motherboard to the
Line-Out connector?
Baiscally, i want to acquire the voltage signal and view it on the oscilloscope. But the problem is that
the signal is not on the " LINE-OUT Connector ", it is on the buit-in speaker on the motherboard.
Any help will be greatly appreciated.

Hello,
Are you using LabVIEW or other National Instruments products to acquire or analyze this signal or are you simply wanting to pass the sounds generated from the on-board speaker to the line-out connector?
Thank you,
Justin

How many airport express can I add to my network for the purpose of using the airport express to send audio signal to different rooms in the house? I'm interested I'm running about six different zones.

How many airport express can I add to my network for the purpose of using the airport express to send audio signal to different rooms in the house? I'm interested I'm running about six different zones.
What I'm looking to do is to have self powered in ceiling speakers in every room in my house with out having to run wires to every room to carry the audio signal. I would like to use the airport express to do the job of carting the audio signal.
Here's my set up now I have an airport extreme and one airport express that I use to carry audio to one room.

FWIW. I have used up to four AirPort Express Base Stations (AX) for streaming sucessfully in pretty much the way you have described. I didn't have a need to try more so I can't attest that more would or would not work.

How can I stop random audio advertising files from playing?

Recently, my Macbook Pro has been playing random audio files. They are mostly advertisments about mucus medicine and news clips about soccer. Yesterday, I discovered that when I quit Safari, the audio stops. Today the problem is back again. What can I do to get rid of these annoying ads?

Safari > Preferences > Security
Make sure that "Block pop-up windows" is enabled.
Temporarily disable the plug-ins
Safari > Preferences > Security > Web content: Enable plug-ins
If the audio is from Flash based ads it should stop.
Re-enable that feature later.
Best.

Bug Report: Audio Signal breaks off, chopped, muted, not playing, stop, cut

This behaviour happens very seldom and by chance, so I had this once with a Space Designer Reverb and now it's happening with a Softsynth. Please listen to this short mp3:
http://www.diedacon.de/piano_cut.mp3
The first piano exactly plays how it is intended: Over the complete length. now i copy this midi block in the arrange window behind it. and another piece again behind the next one. the last two ones play shorter though it is the same lenght!
keep in mind: no automation, any sent midi data commands or sysex behaviour, no overlapping (midi data length is set manually shorter than it's "shell") of audio or midi data is interfering to create this "phenomenon".
For the example of the Space Designer Reverb: Imagine an Audio signal flowing through a Space Designer, which creates a tail of reverb. Now think of the audio signal on this channel completely dissappearing for 1 second at the middle part - it seems, if someone just has chopped some piece out of the audio signal: the reverb continues with it's natural fade out to the end.
same "keep in mind" criteria for the space designer.
Anyone else experiancing "audio cutting", "muting" or "stopping midi data"? This is definately some kind of strange bug.

Well, unless you're using Steinberg 'The Grand' as your softsynth piano it's probably no bug but sth else. Does it happen in solo mode, too ?
( For troubleshooting, it always makes sense to list your audio equipment / drivers and your macs specs in your profile; or at least within your posting, so people have the chance to be helpful. In short : more details, please ... )

Random audio file playing

Hi! I've been having random audio files playing on my RAZR. It sounds like a video that automatically starts playing on websites. However, I'm not on the browser, have windows open, or even using the phone. I unlock the phone and there's nothing in the notification bar. No apps are open on the home screen.
My Alarm Clock Plus app will sometimes play an alarm after I've turned it off. Because there's nothing in the notification bar to stop the music, I have to shut down my phone to stop it. This may be an app bug but has anyone had random audio files playing?

Hi Es80
It sounds like that phone is possessed! Let's get this fixed! It sounds like it may be an application error. Please power the device on in safe mode and retest. Here's how:http://bit.ly/QfA8MZ
Please let me know if the issues persists.

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.

Line-out audio signal of 6G (sixth generation) iPod Classic (120GB)

I suspect that the audio signal that comes out of the Dock Connector of the 6G (sixth generation) iPod Classic (120GB) is not a line-out. Because like the iPod Nano the 6G iPod Classic outputs a signal that can be made louder by turning up the volume from the click-wheel.
Is this true? Am I getting the same signal from the dock as what I have on the headphone port?
For music on the go this is not an issue but if the iPod is one of many sources going into your hi-fi amplifier the experience will be frustrating!
Thanks,
Swake

I have an iPod Classic 120GB and have just connected it to the dock that came with my old iPod Photo (using a piece of cardboard as a dock adapter because, for some reason, the dock design must have changed and the dock adapter that came with the classic won't fit).
I can state that changing the volume level on the iPod has NO effect on the volume coming from the line out of the dock. The line out volume is also much louder than the loudest volume I can get from the earphone socket.
