#2 OpenRadar sound

[Tim Dicus]

I'm having problems with OpenRadar sound. When I start OpenRadar, I get this in the terminal:

2019-01-04 07:16:02,395 [AWT-EventQueue-0] [[ INFO] SoundManager [AWT-EventQueue-0]] - Problem to init SoundManager!
java.lang.IllegalArgumentException: Invalid format
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.createStream(PulseAudioDataLine.java:142)
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:99)

...and on and on.
I use Ubuntu 18.04 with openjdk-8. Flightgear sound works great. OpenRadar has no sound (alerts or FGcom).

You can disable sound processing by icedtea:

sudo bash
nano /etc/java-8-openjdk/sound.properties

comment out lines with icedtea
remove comment character from lines with com.sun.media.sound
Your file should then look like:

#javax.sound.sampled.Clip=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
#javax.sound.sampled.Port=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
#javax.sound.sampled.SourceDataLine=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
#javax.sound.sampled.TargetDataLine=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider

javax.sound.sampled.Clip=com.sun.media.sound.DirectAudioDeviceProvider
javax.sound.sampled.Port=com.sun.media.sound.PortMixerProvider
javax.sound.sampled.SourceDataLine=com.sun.media.sound.DirectAudioDeviceProvider
javax.sound.sampled.TargetDataLine=com.sun.media.sound.DirectAudioDeviceProvider

Thanks! That cured the notifications. I haven't tested FGCom yet.

The latest update fixed this issue. Reason behind was a changed sound api. Please replace your JAR, if you have it installed already.
