WAV file won't replay in LabView or load in WMP, but works in VLC

I'm creating an audio file for an interview with the code snippet attached (VI is very large and does a lot of unrelated processing). This audio is recorded in the "interview" subvi. At completion, this subvi is closed and the "process" subvi is opened. If this process is followed, labview will open and play the WAV file with no problem. Alternatively, "process" can be run as a stand-alone. If this is done, I get the error 4810 at Sound File Read Open (possible reason: cannot recognize sound format). If I try to open the file in Windows Media Player, the wav will open, but will have a length of 0. If I open the wav in VLC, it plays with no problem. I haven't tried saving as a new file, but this is a sortof untenable solution anyway. For what it's worth, this problem arose when the audio recording was changed to a queue-based process. I've attached the old (working) code for reference.
Thanks,
Brendan

I'm also adding a screen cap of the working (right) and non-working (left) headers created by the snippets attached above. I don't have a lot of experience with this, but it strikes me as curious that the non-working (left) header has no value for what I think should be the File Size (data) section (as referenced here http://www.topherlee.com/software/pcm-tut-wavformat.html). I note also that the header seems to be 12 bytes longer that most references suggest, but this is the case in both the working and non-working headers (I'm looking specifically at offset 36-47 in both).

Wav files won't play in Firefox 22

Wav files won't play in Firefox 22. Previous versions of Firefox are fine. Other sound is fine. I have the latest mac OS X. Quicktime is set to play wav files. I have the latest version of it.
Is there a fix for this?
Is there any other plugins I can install which will play the wav files?

Thank you for your response Alice.
I checked about:plugins and I DO have audio/wav and audio/x-wav. It it QuickTime 7.7.1 I have.
In Firefox Preferences Applications Panel I do not seem to have the iTunes.Document audio/x-wav there, only the audio/wav and Waveform Audio.
Re the New Email Notification feature with my Webmail, this is not activated via a Firefox extension. I don't really know how it works but when I'm logged into my Webmail email account and a new email arrives, a wav sound is played to alert me of the new email. This has always happened with all previous versions of Firefox, just not since I updated to Firefox 22 but when I go back to Firefox 21, it works again.
I have previously asked about this with my Webmail company. They knew nothing of this problem. I have now asked them for a second time now that I know that it is only THEIR wav sound that won't play. Other wav files play OK with Firefox 22.
I do not know what is at fault - Firefox 22, QuickTime or the Webmail site but for the past few days I have frequently switched between Firefox 22 and Firefox 21. Each time the New Email Notification wav sound works with Firefox 21 and doesn't with Firefox 22 so that makes me suspect that somehow Firefox 22 is at fault.
But it is a mystery and I might be stuck with it - unless it disappears as mysteriously as it arrived with a newer version of Firefox or maybe even a newer version of Quicktime.
Thank you to everybody who has tried to help me.

MBA won't connect to iPhone or Jambox via Bluetooth, but works with bluetooth Apple Mouse

MBA won't connect to iPhone or Jambox via Bluetooth, but works fine with bluetooth Apple Mouse. When trying to pair with the iPhone it says "The Bluetooth Network is unavailable. There was an error connecting to your device. Make sure the device is turned on and in range." When trying to connect to the Jambox it says "Bluetooth audio failed. There was an error connecting to your headset. Make sure it is turned on and in range. The audio portion of the program you were using may have to be restarted." The iPhone and Jambox pair together fine, and I have paired with both the iPhone and the Jambox easily in the past. I haven't updated anything - it just stopped working with these two devices. This is very frustrating.

I could not pair with Uconnect on a 2011 Jeep after upgrading to iOS 8.2 on an iPhone 6. After shutting off iCloud and resetting network settings I was able to successfully pair the phone to Uconnect

I have pc with itunes loaded on seperate hard drive and can't find all music some from ripping in wav files won;t show but any and all i've downloaded from itunes store are there what,s up/ /?

Having trouble getting my music from seperate hard drive. Recently tried to have my new laptop see and play itunes on my wireless server, but not all music showed up, and now my music on my pc doesn't show all music either. Some wav files from ripping off cd, and some I've imported from windows media show up and all mp3 bought from store is there. But more than half is listed at bottom of library as unknown artist, unknown album etc.. WHATS UP!!!!

try backing up the adresses on a different computer.
1) connect iphone to computer
2) in itunes click "enable disk use"
3) locate the files in the iphone hard drive
4) copy and paste them on that computer
if it does wipe out your adress library, just revert to the backup. Although i don't know where the files will be on your iphone hard drive.

WAV Files won't play on Windows Vista Home Premium

We have a HP Desktop PC running Windows Vista Home Premium. Just recently, certian sound files quit playing. We also noticed that the system sounds quit working as well. After looking into it more, I figured out that the drivers are all up to date, that iTunes plays music just fine, and that the internal error beeper in the tower replaced the error.wav when an error window pops up. I have run defragment, check disk, and other system scanners. None of these seemed to help. Does anyone know what the problem may be?

Have you checked the HP Website and Microsoft Support websites to see if they have any solutions to your problem? Since there could be multiple things causing this, I would check at the places I mentioned first and see if their knowledge base contains an answer.

Flash file won't replay?

I am in AS3.0
I have created a linear flash file to show the steps of a user flow.
This uses a single 'next' button which navigates through the flow and at the final screen navigates back to the first screen to allow the user to view the file again.
However it sticks at screen1 and will not progress.
I have addressed the following points suggested by someone else,
1. make sure your button listener code is on the first keyframe that contains your button.
2. your button should be on its own layer
3. that layer should extend to length of your timeline
4. there should be no keyframe in your button's layer OTHER than the first keyframe. ie, there's only one keyframe containing your button and your button exists throughout your timeline.
but it still doesn't work.
Any help is much appreciated.
Max

What you just described isn't really following the intent of what was recommended to you. Is there any chance you could show a screenshot of the timeline down at the scene1 end? I am anticipating that the code that would be assigned in scene1 is not being assigned again, possibly because you miss that frame on returning, though I may be wrong.
What you might consider doing instead is to only assign one listener to that button, back in the first frame it appears in (no other keyframes on the button's layer) and have it use a variable that you assign the next screen's frame label value (call it nextSection or something).
next.addEventListener(MouseEvent.CLICK, clickNext);
function clickNext(evtObj:MouseEvent){
gotoAndStop(nextSection);
and that nextSection variable would be declared in the first frame of a layer that also extends the length of the timeline so that it is accessible anywhere for assignment and retrieval.
var nextSection:String;
and you would assign it the next screen's frame label when you arrive at each screen.... nextSection = "screen5";

Facebook & eBay Won't Load With Ethernet, But Works With 3G... :/

Hi Apple fans!
I'm writing in regards to a weird internet problem that I have. Right now I am using an ethernet cable to go online on my Macbook Pro, and every website works. Well, every website but Facebook and eBay.
I'm sure there are just more than those two that don't work, but in any case these are the two that I frequently use that and that need to be working.
Strangely, when I tether my Macbook Pro to my iPhone's 3G, Facebook and eBay start working. Does anyone know why? Are there any solutions that I can try to get access to these websites again?

Why won't my iMessages go through to my friend but works with others? iMessage is activated on both phones

I can iMessage friends and they receive my messages except for one friend who has not been receiving my iMessages sent to him. If I turn off iMessages he receives my text messages. I can receive iMessages from him and reply but I can not initiate the iMessage. My iMessages are going out successfully to others. I have done a hard restart, turned iMessage off and back on, and deleted his contact info and added it back to my contacts.

Is there a not sent indicator on the message initiated by you, or is the message sent but not received?
If no problem with anyone else and the only problem is on the recipient's end, doubtful the problem is on your end.
What has the recipient done?

How to load XML file to table (non-XML) with SQL*Loader -- issue with nulls

I have been attempting to use SQL*Loader to load an XML file into a "regular" Oracle table. All fields work fine, unless a null is encountered. The way that nulls are represented is shown below:
<PAYLOAD>
<FIELD1>ABCDEF</FIELD1>
<FIELD2/>
<FIELD3>123456</FIELD3>
</PAYLOAD>
In the above example, FIELD2 is a null field and that is the way it is presented. I have searched everywhere and have not found how I could code for this. The issue is that if FIELD2 is present, it is coded like: <FIELD2>SOMEDATA</FIELD2>, but the null is represented as <FIELD2/>. Here is a sample of the control file I am using to attempt the load -- very simplistic, but works fine when fields are present:
load data
infile 'testdata.xml' "str '<PAYLOAD>'"
TRUNCATE
into table DATA_FROM_XML
FIELD1 ENCLOSED BY '<FIELD1>' AND '</FIELD1>',
FIELD2 ENCLOSED BY '<FIELD2>' AND '</FIELD2>',
FIELD3 ENCLOSED BY '<FIELD3>' AND '</FIELD3>')
What do I need to do to account for the way that nulls are presented? I have tried everything I could glean from the web and the documentation and nothing has worked. Any help would be really appreciated.

I hadn't even got that far. can you direct me to where the docs are to import data that is stored within xml but that you don't need any xml functionality, that just happens to be the format the data is stored in? thx

Logic X won't import a 64 bit .wav file. Why?

I'm trying to import .wav files created with FF Tools into Logic for some editing, but it says the audio file is "in a 64 bit format and cannot be used". Why is this? I thought Logic X was 64-bit friendly?
Any help on this would be greatly appreciated.
Thanks

There is also no point in using 64 bit audio files. Even 32 bit floating point is already overkill. The best choice for recording is 24 bit, for internal processing 64 bit floating point does make sense, but not for storing.
In any case, your mac comes with a very capable audio file format converting utility that can be used from the command line and reads/writes practically any audio file format you will encounter, including 64 bit wav. Type "afconvert" on your command line in terminal.app to see the options it offers. If you're not used to using the command line you might find this very uncomfortable, but it's really worth getting into it.
Let me know if you need help,

Embedded wav files not playing in IE7 after installing QT 7.3

I created a web page that uses javascript to play embedded wav files on an onclick event. I was having trouble with my Firefox browser not playing the wav files at all, so I thought I'd update from QT 7.1 to QT 7.3. This has caused my IE browser to stop playing the embedded files, and has not helped my Firefox browser, either. Uninstalling QT 7.3 does restore IE7's ability to play the embedded files. I'm using some simple popular Javascript for the function, and the page works for me in my home installation of Firefox, so I'm still mystified why the wav files won't play on my workplace Firefox (yes, I tried disabling all the other plugins, to no avail), and also, I need to fix IE7 now, as well. QuickTime Object is enabled in IE's add-ons list.
I did search all over the knowledge base here and at Firefox's site for solutions.
Suggestions?

Internet Explorer requires the "object" tag code and your html only uses "embed".

Why can't I manually fill in info for some WAV files?

I've been importing wave files into itunes and filling in the artist info manually, one cd/playlist at time, with the intent of later converting the entire library to apple lossless. I need to do it this way because importing one CD at a time, I select the whole thing, and then fill in the info for the entire selection at once. If I import a bunch of files first I get a huge disorganized mess because there is no "tag" info. The problem is that, for some reason, artist info entered manually for some WAV files "won't take" but if I change to apple lossless first it will. Can anyone suggest a reason for this inconsistant behavior in the iTunes program?
Gerry

WAV files don't have ID3 tags, which hold a lot of the song info.

Need Help playing a wav file on PDA

Does anyone have a SIMPLE example of playing a wav file on a PDA using LabView PDA. The only working example I can find from NI "Advance Sound Example for LabVIEW PDA for Pocket PC" is a jumbled of confusing functionality. I'm mainly looking for a simple "play" example, but a simple "record" example would be helpful also.
Thanks - Bruce

Hello,
Well, I looked through the example code I tried to break it down to the point where you could create a simple Play VI. Unfortunately, I don't have the PDA target, so I'm uncertain if the little example that I have attached will run or not. If not, I also took a screen shot so you can see what VIs I used. I'm pretty sure I only used VI's that I found on the example itself.
Good luck.

Playing a .wav file loaded from filesystem

I am trying to play a local file and getting:
Have not been able to load: MediaError: media unsupported:com.sun.media.jmc.MediaUnsupportedException: Unsupported media: file:///product-name/lib/buzzer.wav
I get a different exception if the file does not exist, so the message seems to be saying it has a problem with .wav files, or this .wav file in particular??
I am using 1.3, but this page is for 1.2:
http://download.oracle.com/javafx/1.2/tutorials/media/format.html
There doesn't seem to be an equivalent page for 1.3. If 1.2 rules still applied then for Audio on Vista the resolution under 'Supported Media Codecs' is "All the audio formats supported by Windows Media Player". And [this file|http://www.strandz.org/javafxstreaming/buzzer.wav] certainly works on Windows Media Player.
package def alarmSoundPlayer = MediaPlayer
    media: makeFilesystemMedia( "file:///product-name/lib/buzzer.wav");
    autoPlay: false;
    repeatCount: 1;
public function makeFilesystemMedia( fileName: String): Media
    var music = Media
        source: fileName
        onError: function( mediaError: MediaError)
            println( "Have not been able to load: {mediaError}");
    return music;
}

It might not be the issue, but the file:///product-name/lib/buzzer.wav is strange. Aren't you missing a drive specification? (might not be necessary if on the same disk, but still unusual). Is the "product-name" at the root of the disk? When in doubt of URL syntax, you can still use a path to initialize a File object, then get toURI().toURL() to have a normalized URL.
HTH.

Error Playing .wav file on RHEL 4 using JMF

Hi,
We are using jmf api to play wav files on our application deployed on rhel version 4. But we are receiving the following error
**"Cannot find a Processor for: myfolder/myAudio.wav" --->
this exception is comming from javax.media.Manager
throw new NoProcessorException("Cannot find a Processor for: " + source);"**.
Any ideas what could be issue with this, am I missing some drivers/processor for wav files? I did a default jmf studio installation.
Thanks and Regards
Vikram Pancholi

If we take a look at the supported formats page...
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/formats.html]
And the WAV file is supported by the cross-platform pack, AKA, jmf.jar.
If you're unable to open a WAV file, I'd say it's most likely because you don't have JMF.jar on your library path. You can fix that at runtime with the switch -djava.library.path=<whatever>
That's what I would say the issue is.
