How to play DTS wav files on hd from sounblasterplay
Hello,
I've got many wav files on my harddisk. They are dts wav files.
On cd-rom they play with software player soundblaster, no problem.
But when i play them by harddisk there is no dts sound.
What must i do to play them?

How to play a wave file through the DAQ board?
Hi there,
we want to play a wave file that is saved on the harddrive via the DAQ board. Means we want to connect a amp to the analog output of the DAQ to amplify the sound and play it through a speaker.
We couldn't find any VI that does that. Can anybody tell us how to play a wave file, or perhaps even send us a VI that can do that?
Thanks a lot for your help
Martin - Physical Optics CorporationHi Martin,
The only example that I could find on how to do this was using our
older Traditional DAQ drivers version 6.9.3. If you're using Traditional
DAQ drivers, the vi can be found here.
The example reads a 8-bit mono .wav file (an example .wav file is included in the .zip file) and writes it to the analog out of your DAQ card. I've updated the
example to work with our newer DAQmx drivers and attached it here.
I hope this helps,
Paul C.

How to play a wav file to LINE_OUT with javax.sound.sampled
Hello all,
I need to play a wav file to LINE_OUT port, but not to the SPEAKER. I am trying to do this under window NT. For some reason I get false for isLineSupported(Port.Info.LINE_OUT). I am new to javax.sound so I might be doing something wrong. Here is the code that I am using to iterate through all availible mixers and check if LINE_OUT is supported by any of them:
Mixer.Info[] mixers = AudioSystem.getMixerInfo();
for(int i = 0; i < mixers.length; i++){
Mixer mixer = AudioSystem.getMixer(mixers);
if (mixer.isLineSupported(Port.Info.LINE_OUT)) {
System.out.println("the port is supported");
try {
Port line = (Port) AudioSystem.getLine(
Port.Info.LINE_OUT);
catch(Exception ex){
ex.printStackTrace();
else{
System.out.println("the port is not supported");
Please helpThe new bugID of the request to implement Ports is: 4558938.
(If you voted for the old bug id: 4504642, be sure to change your votes to this new bug report since the old one was closed as a duplicate of the new one.) -
just wondering. Doesn't seem to be an easy way to do this. Bought a dts cd of music and ripped it as best as I could and they came out as wav's.I've tried using Quicktime player, Vox and VLC to play 'em but all I get is white noise, so I know something's wrong. Quad core mac, 3 tb space, OS 10.9 GT8800 video card, and some multichannel speakers........
Any help appreciated
thanks
John bsorry, I think it's a dvd-Audio, encoded in dts. I may just have to say "to heck with it" and use my dvd player by my tv to play this.... or quit trying to rip them

How do I play the .wav file google mail sends me on my Iphone 5?
I have cable phone service that sends out a .wav file of any voicemails I recieve to my e-mail account. I use google mail on my Iphone, and cannot play the .wav file that is attached to that e-mail. When I click on the "audio message box", it brings up a circle containing a south-west facing arrow which has a slash through it.
I have the latest software (6.1.4) and I can play the attachment if I go through "Mail" instead of "GMail". I am still not certain why I have a widget called "Mail".
Inside the "Mail" app, there are it's own Inbox, VIP, Flagged, etc which are all in color. Further down the list is my GMail boxes and sub-boxes. They are all grayed out, but still funtional.
Do I have something set up wrong causing me to be unable to play the .wav files that come to me through gmail? -
How to play an audio file through a button?
I have a form in which I have a button (Command object). When the user clicks on this command button it is supposed to play a wav file. The wav is residing in my hard disk at "C:\tada.wav"
I have tried to include the following code in the commandAction() method, which technically is the right way of performing this operation:
But I get a warning when I compile saying that this operation should be performed in a seperate thread as opposed to commandAction().
if(c == cmdPlay)
try
String wav = "file:///c:/tada.wav";
Player p = Manager.createPlayer(wav);
p.start();
catch (IOException x)
x.printStackTrace();
} catch (MediaException x) {
x.printStackTrace();
Can anyone please tell me how to implement this solution properly or just suggest a new way of creating a "play" button in my form? Urgent HELP NEEDED PLEASE!
THANKS.Hi Ibrahim,
Rob has pointed you to the Lingo for playing a sound. There is a behavior in the Library Palette that makes this very easy without needing to write a script yourself. In the Media > Sound category, there is a 'Play Sound' behavior. You can click and drag this behavior onto a sprite and then in the Parameters dialog, you can choose the sound to play, the channel in which it should play, the event to activate the sound, and if you want the sound to loop.

Subsequent play of WAV files from HTTP
Hi,
I have to subsequently play many WAV files from HTTP in a nokia series 60 emulator.
Everything is ok for the first two files, but at the third I catch an exception:
"java.io.IOException: exceeded the configured maximum number of connections"
I tried two ways to load the files from HTTP:
Manager.CreatePlayer(InputStream...)
Manager.CreatePlayer("http:\\...")
Below there is the code of the two methods I use. Please note that I try in every way to close the connection before open a new one!!!
public void Method_1(String src, String type){
int iLen=0;
is = null;
httpCon = null;
byte[] bBuf;
try {
if (p != null) {
if (p.getState() == Player.STARTED) {
p.stop();
p.removePlayerListener(this);
p.deallocate();
p.close();
p=null;
if (is!=null){
is.close();
is=null;
if (httpCon!=null){
httpCon.close();
httpCon=null;
httpCon = (HttpConnection) Connector.open(src);
if (httpCon.getResponseCode() != HttpConnection.HTTP_OK) {
System.out.println("Bad response code");
return;
System.out.println("Connection OK! (audio)");
iLen = (int) httpCon.getLength();
System.out.println("audio file length : " + iLen);
is = httpCon.openInputStream();
p = Manager.createPlayer(is, type);
p.addPlayerListener(this);
p.setLoopCount(1);
p.prefetch();
p.start();
vc = (VolumeControl)p.getControl("VolumeControl");
catch (MediaException ex) {
ex.printStackTrace();
catch (IOException ex) {
ex.printStackTrace();
public void Method_2(String src){
try {
if (p!=null){
if (p.getState() == Player.STARTED)
p.stop();
p.deallocate();
p.close();
p=null;
p = Manager.createPlayer(src);
p.addPlayerListener(this);
p.setLoopCount(1);
p.start();
vc = (VolumeControl)p.getControl("VolumeControl");
catch (java.io.IOException e) {
e.printStackTrace();
catch (MediaException e) {
e.printStackTrace();My question is:
how can I load (from a HTTP server) and play more than two WAV files without crashing?
Do I have to close the connection in a better way in order to re-open it without problems (and more than two times)?
It is simply an emulator bug?
Thanks. -
how do I play a wav file just once using the play sound
file.vi. i keep getting it to repeat over and over
thanksFirst may I recommend some reading here. This is not meant to be cocky just to help you.
Getting Started with NI LabVIEW Student Training
LabVIEW101
Second I have included sort of template. Notice the wire that ends in the while loop. This will ensure that the wav is played before the loop starts.
Good luck with your Labview labwork
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Playing a wav file (byte array) using JMF
Hi,
I want to play a wav file in form of a byte array using JMF. I have 2 classes, MyDataSource and MyPullBufferStream.

These are my modem commands
send("ATZ");

//Enable voice mode
send("AT+FCLASS=8");
expect("OK");
//Dial the number
send("ATDT"+number);
expect("OK");
//Choose encoding method //This is the default
send("AT+VSM=140,8000,0,0");
expect("OK");
// start sending audio data
send("AT+VTX");
expect("OK");
PlayAudio();
send("ATH");The size of my audio file is 100 kb.I'm using a 56 K intel externel voice modem connected to a serial port.I wonder if it's because the buffer is too big. If anyone tried this and succeded please correct me.
Thankyou in advance

this could help you starting. For the case you can't open LV 8.2- VIs, i attach the BD- picture.

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 - BruceHello,
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.
