Now I am able to play two independent song in left and right earphone using below mentioned pipeline.
Can you please suggest me how to play a song in only one earphone using interleave plugin again. This will help in our application wherein we will not play two songs all the time.

Thanx Thiago.
i just interchanged the sink pads and its working for me.
gst-launch interleave name=i ! alsasink filesrc location=test.mp3 ! decodebin ! audioconvert !  audio/x-raw-int,channels=1 ! i.sink1  filesrc location=/song.mp3 ! decodebin ! audioconvert ! audio/x-raw-int,channels=1 ! i.sink0 This plays two songs differently.

gst-launch interleave name=i ! autoaudiosink filesrc location=... !
decodebin2 ! audioconvert ! audio/x-raw-int,channels=1 ! i.  filesrc location=... ! decodebin2 ! audioconvert ! audio/x-raw-int,channels=1 !
i.

This works for me. Note that I used decodebin2 instead of decodebin, that I removed the names for the interleave pads and let gst-launch select them automatically, and that I added an extra audioresample.
