<Sound Dev> JavaSound is not actually usable on Oracle JDK

[Damjan Jovanovic]

Which Linux distribution are you using?

On at leaset Ubuntu the default jre/lib/sound.properties for OpenJDK only
contains these lines:

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

so it's using IcedTea's PulseAudio driver instead of Oracle's ALSA driver.
That may account for the difference you are seeing.
