I would like to ask if there is any possibility to access the cdrom device via sound libraries in Java.
What I want to do is to mute CD Analog. I've searched using google for a long time, but there is no information about such an operation. I assume that this is trivial or very complex.
This simple code list my mixers:
try
{
Mixer.Info [] mixerList = AudioSystem.getMixerInfo();
for (Mixer.Info mixerInfo : mixerList)
{
System.out.println();
System.out.println("MIXER: "+ mixerInfo.getName());
Mixer mixer = AudioSystem.getMixer(mixerInfo);
Line.Info[] li = mixer.getSourceLineInfo();
System.out.println("LINES:");
for (Line.Info info2 : li)
{
System.out.println(info2.toString());
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
The output is:
MIXER: Primary Sound Driver LINES: interface SourceDataLine supporting 8 audio formats, and buffers of at least 32 bytes interface Clip supporting 8 audio formats, and buffers of at least 32 bytes MIXER: Speakers (Realtek High Definition Audio) LINES: interface SourceDataLine supporting 8 audio formats, and buffers of at least 32 bytes interface Clip supporting 8 audio formats, and buffers of at least 32 bytes MIXER: Primary Sound Capture Driver LINES: MIXER: Desktop Microphone (Cinema - Mi LINES: MIXER: Microphone (Realtek High Defini LINES: MIXER: Port Speakers (Realtek High Definiti LINES: MIXER: Port Desktop Microphone (Cinema - Mi LINES: MICROPHONE source port MIXER: Port Microphone (Realtek High Defini LINES: MICROPHONE source port
But there is no such device like cd analog. When I try obtaining a particular port from the mixer using Port.Info.COMPACT_DISC there is an exception no such device.
Can anybody assist me with this issue?
Have a look at java-avm library:
java-avm (Audio Video Media) is a Java API for accessing and controlling disc drives, particularly CD-ROM and CD-R(W) drives, removable drives, and loopback devices.

CD-ROM Specific:
- Control CD-Audio playback with volume adjustment.
