I did not configure any JVM's audio output. If it is required, how should I do? Doing so, will it help? Pardon me, I'm quite new to all this. Please help me in doing that. 

I'm able to play multiple audio files being played simultaneously with aplay command. But this is not the case with java in picture(with the jar file). So, as you said may be I need to configure JVM's audio output. Can you help me doing so?

Also, should I re frame the question, if it is not clear?

Some more details:

[sai@sai ~]# sudo cat /proc/asound/version

Advanced Linux Sound Architecture Driver Version 1.0.24.

[sai@sai ~]# sudo cat /proc/asound/cards

0 [Intel]: HDA-Intel - HDA Intel

             HDA Intel at 0x80300000 irq 46

[sai@sai ~]# aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: Intel [HDA Intel], device 0: ALC886 Analog [ALC886 Analog]

Thank you very much once again.

Sai

How did you configure the JVM's audio output?
