Hi,
i'm using an USB MIC on a Raspberry and i'm developing with the JAVA SOUND API
but the Line is Not Supported, why?
I've executed this code on a normal PC with Linux and it works (the Line is supported and the Mic works)
What is missing? how can is get Line Supported?
the cose is this:
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.Mixer;
import javax.sound.sampled.Port;
import javax.sound.sampled.TargetDataLine;
public class TestAudio {
public static void main(String[] args) throws LineUnavailableException {
Mixer.Info minfo[] = AudioSystem.getMixerInfo();
for (Mixer.Info minfo1 : minfo) {
System.out.println(minfo1);
}
if (AudioSystem.isLineSupported(Port.Info.MICROPHONE)) {
System.out.println("++ LINE IS SUPPORTED ++");
} else {
System.out.println("Line is NOT supported");
}
}
The output is this:
ALSA [default], version 4.9.54-v7+
ALSA [plughw:0,0], version 4.9.54-v7+
ALSA [plughw:0,1], version 4.9.54-v7+
Device [plughw:1,0], version 4.9.54-v7+
Port ALSA [hw:0], version 4.9.54-v7+
Port Device [hw:1], version 4.9.54-v7+
Line is NOT supported
