Interactive play sound file.vi crashs labview

While playing with a *.wav file to perform an FFT on the data, I tried running this VI. Labview then crashes. No error.

Which version of LabVIEW are you using? I'm using LabVIEW 2011 SP1, and I ran the "Interactive Play Sound File.vi" from the example finder and the VI worked for me.
Are you just trying to play a sound file in your own VI? If so, the DLL library call from the example could be causing the crash. It could also be that your program isn't crashing, but just terminating before your sound file has a chance to play.
There is an easier way to play a sound file, just use the "Play Sound File.vi". You may also need to use the "Sound Output Wait.vi" to prevent your LabVIEW program from terminating before the sound has a chance to play. I've attached a picture of the setup I'm refering to.

How do you open/play a .wav file (music file) without play sound file .vi

I am having big problems to create a music background for my project. I am newbie using labview and maybe my questions is not so dificult to solve (I hope so)
I was using play sound file vi but the problem is that I dont want the music file start automatically. I wanna control the start time using a button. I tried include a sound output stop but when the app start and I add more wav files in my vi, the sound file start, then stop abruptally because the stop vi and the everything is normal. I would like to eliminate that error.
Someone have any idea, maybe using open file or another way.
Thanks in advance
I add a screenshot of my vi and also the vi in this post

Unable to load/play sound files using SoundEngine_LoadEffect

Hi All,
I am able to load/play sound files using SoundEngine_LoadBackgroundMusicTrack but unable to load/play sound files using SoundEngine_LoadEffect on iPhone Simulator. I am using the SoundEngine.h/cpp from Crash Landing. Oddly enough sound effects load and play succesffully when i start the app with 'Start with Performance Tool'. Does anyone know what is actually going on.
Also i would like to know what is the difference between playing sound files using these two methods. What are the restrictions on individual sound file types for each method.
Thanks

I was able to load/run the sound effects after using Simulator - iPhoneOS 2.1 in the Active Target/Build drop down on Xcode toolbar. Both Active SDK, and Active Executable should be 2.1 in order to play the sound effects.

Help on Play Sound File.vi - file format

Hello,
My request is quiet simple but I don't understand why it doesn't work.
I want read a .wav sound file with the Play Sound File vi. But when I run the vi, an error message appears " Cannot recognize sound format"
I have tried with different .wav sound files but nothing works.
Do you know why this error happens ?
Thanks

Ok thanks.
Since the last time I posted I've tried many other wav sounds but nothing works I still had the same Labview error.
I join you few of my wav files and maybe you can try it.
Thanks

Are you loading your Applet from a webserver? You could make the sound file available through the same webserver.
Alternatively, you could package the sound with the code in a JAR. It does mean a bigger download for your Applet users though, but the Applet would be able to access the file quickly.
If you put your file in the JAR, say in /sound/myfile.ext , then you can get access to it from your code like this:
URL soundURL = getClass().getResource( " /sound/myfile.ext" );

What's the best solution for audio out of sound files from a MacBook Air to both an amplifier and to a subwoofer amplifier? I'm using the MBA to play sound files for worship services at our church.

I have a MacBook Air (13", 1.7GHz, 8GB RAM, 500GB SSD) that I'll be using to play sound files (primarily organ and piano) for worship services at my church. We'll be using a QSC RMX2450 650 Watts/Channel amplifier with Community CPL-27 speakers and also a JBL SUB 250P powered subwoofer with its own amplifier. What's the best option for getting sound out from the Mac to both of these amplifiers?

if you work with own recorded sounds you might wanna have a music program where you want to work with samples, steinberg has got very good ones (so they say)... but their really really ( ²) expensive(that's why almost no one haves them), magix haves good ones too bu their more for 'unprofessional' use, ableton haves really good ones too and they're not to difficult to use (if you know a bit of those programs you learn very quickly) and if you don't get them, there is a sort of manual built in it which explains and lets you do things to start (basics)
i hope this helped, btw stereo speakers are always better if you buy good ones (no pc speakers), but if you don't think you need them, don't buy them...
so again, i hope you have some ideas now

How to play sound file in Forms 9i using PJC.

Hi ,
I want to play a sound file in Forms 9i over the web using "Pluggable Java Component". Any pointers / help in this regard will be highly appreciated.
Thanks in Advance,
Vinod.

Vinod,
just do a search on the Internet for a Java Bean and add this to Forms. However, if you don't necessarily require the sound to be played from within Forms, you could use web.show_document() to call it in a URL displayed in a hidden frame on the Forms HTML page. This way it would be the browser playing the sound (assuming a proper Plugin)
web.show_document('http://server:port/myDir/mysound.wav','myHidden_frame')

Audition CS5.5 Won't Play Sound Files

Just recently I have not been able to play any files that I have loaded. In the bottom left hand corner, it notes that the file(s) is either playing or stopped when I press play on the transport, but the cursor won't move and sound will not come out. Below is the screen shot that I think might be the culprit, but I am not totally sure. I am using Audition CS5.5 on an iMac. Thougths?

Well, that's certainly a clue--Audition isn't finding your sound card. You don't say what you have but the first thing I'd try is reloading your sound card drivers.
Also, on the other Preferences menu (Audio Hardware) check that you have the proper sound card and driver class selected.
Finally, depending on what version of Windows you have, it might be worth going to the Windows Audio menu and check that Windows hasn't disabled the device you wish to use for some reason.

File dialog crashes LabVIEW 2014 on Mac OSX Yosemite

I know that Mac OS 10.10 (Yosemite) is not technically supported by LabVIEW 2014. If that's the only answer to this question, then so be it.
The following causes LabVIEW 2014 to crash on Mac OSX 10.10 (Yosemite):
1. Run the native File Dialog in LabVIEW 2014 (Express VI) , using "New or Existing File" as the selection mode
2. Select "New File..." when the file dialog appears
3. Enter anything as the file name and click OK
4. LabVIEW either crashes immediately, or hangs indefinitely and must be force quit.
Is there an update for LV 2014 (and the RTE) that does support Yosemite?
This bug makes deploying apps to the Mac basically impossible, Yosemite is the latest OS. Does anyone have a workaround for the issue?
Thanks.

LabVIEW 2014 SP1 seems to solve that problem here on my Mac OSX 10.10 system.
Now Apple may be nice for end users, but all those Apple fan boys sure would think a little different about it, if they had to write programs on the Mac. Apple keeps changing its APIs and their behaviour continously, inventing new APIs (which is fine) in a rapid pace, only to depreciate and remove older APIs at almost the same speeed!
Microsoft sometimes goes to the other extreme with maintaining backwards compatibility but working with Apple systems surely isn't easy as a programmer (unless maybe when one uses their high level click and point together web design applications, but I don't know that).

JMStudio locks up playing sound file - using java 1.5.0_02 - HELP!

I'm using the jmf 2.1.1e cross platform version on Windows XP SP2. I have java 1.5.0_02 installed.
When I open the sound file using JMStudio it locks up. It plays videos that don't have sound fine, so it's not the video. It's the sound that is killing it.
Does anyone have any suggestions?

Hi,
yeah it's possible to play sound on Windows but you have to use the Windows Performance Pack instead of the crossplatform-version of JMF.
This has to do with the JavaSound Architecture of Java 5.0. They made changes and now the JavaSound Renderer didn't work under Windows but the DircetSound Renderer works fine.
So be sure that your application uses the DirectSound Renderer!
This is one of the main problems of JMF but now Sun gets interested in JMF and they would build a new version of JMF. If this is true they have to fix this problem!
Best regards, thomas

IPhone (Cocoa Touch) Button that plays sound file on click?

Hello.
I am trying to create a button that, when clicked, it plays a given sound file in the app's filesystem.
This is what I have set up thus far:
Regular Rectangular button -> connected to NSObject Called "sounds" -> with the Event "playsound1" chosen as the event.
I then wrote the class files, brought them into Xcode file project under classes, and now I'm staring at sound.h and sounds.m with no idea what to do next.
I was able to create in a regular Mac OSX Cocoa, a button that plays the system beep using NSBeep. However, I don't know how to achieve this similar objective with using a given sound file in the iPhone Cocoa Touch.
Thanks

I have tried so many things. I'm so lost.

How to play sound file on HTML

I have successfully able to record voice and save it into the database and replay it. Also able to store an external wave file and replay it using forms.
I need to play the same soundfile from database on HTML using PL/SQL.
Would appreciate if someone can support my problem. I need to know the package to read and play the database column storing sound.
Thanks and Regards,
Vipul

Hi Vipul,
Great to know that you could record a sound file and save it in Oracle and play it through Forms. We are having a similar requirment. Could you please list down the steps of exactly how did you achieve this ?
It would be of great help to us if you can clear us the same. Thanks in Advance.
Thanks,
