7650 wav error

[Malcx]

Hi,
I'm trying to play a five second wav on a Nokia 7650 - when the code below tries playing the wav, the app closes and an error message is displayed with:

App. closed
jes-1f1-javax.microedition.lcdui0@1...
CMdaAudioPlayerU 2


/* code start */
try{
InputStream tune = this.getClass().getResourceAsStream("/resources/sound/4.wav"
byte[] bytes = new byte[50000];
tune.read(bytes,0,bytes.length);
Sound talk_S=new Sound(bytes,Sound.FORMAT_WAV);
talk_S.init(bytes,Sound.FORMAT_WAV);
talk_S.setGain(40);
talk_S.setSoundListener(this);
talk_S.play(1);
}
catch(Exception e){
osText p4_item_ex = new osText(debugNo + " "
thisPageItems.addElement(p4_item_ex);
osText p4_item_ex2 = new osText(e.toString());
thisPageItems.addElement(p4_item_ex2);
}

/* code end */

If I remove the line
talk_S.setGain(40);

No error is reported but equally no sound plays.

Any suggestions?

The setGain is what is causing the crash - this is a known problem. Are you sure the wave file is compatible? Try sending it to the phone as a file and see whether you can play it in the sound recorder application.

Hi,

I had huge problems with .wav files... they were never played...
Problem was that I belived to the posting that 7650 will play 16 bit 8 kHz files with ADPCM compression... I took that as a fact because someone from nokia support wrote that.
Well, obviously, the person that wrote this has no clue about what 7650 can! I spent the whole day trying to get some tone out of the phone with no success until I conevrted my sounds back to:
8bit, 22 kHz, mono
This will work for sure!

Also, you should remove the setGain from your code... this command is definitely not working.

Dejan.

Hi just an update,

The ultimate problem was unfortunatly a defective 7650 ;-(

Thanks for the comments though!

But the setGain is still busted.
Do NOT use it.
