Error in playing multichannel audio at different instances on am335x evm!!

[PragyaRai]

I am trying to play 2 channel audio, in which mp3 in one and silence in other channel is being played.

    $ gst-launch \
        interleave name=i ! alsasink
        filesrc location=/home/test1.mp3 \
            ! decodebin ! audioconvert \
            ! audio/x-raw-int,channels=1 ! i. \
        audiotestsrc wave=silence \
            ! decodebin ! audioconvert \
            ! audio/x-raw-int,channels=1 ! volume volume=1.0 ! i.

After 10 sec I want to play silence in first and some mp3 in the second channel.

    $ gst-launch \
        interleave name=i ! alsasink \
        audiotestsrc wave=silence \
            ! decodebin ! audioconvert \
            ! audio/x-raw-int,channels=1 ! i. \
        filesrc location=/home/test2.mp3 \
            ! decodebin ! audioconvert \
            ! audio/x-raw-int,channels=1 ! volume volume=1.0 ! i.

This can be done on PC's side, while playing these pipeline in two different terminals or making one of them run in background. But when I am playing one pipeline on am335x board and trying to play the other one, its something like this:

    Setting pipeline to PAUSED ...
    ERROR: Pipeline doesn't want to pause.
    ERROR: from element /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Could not open audio device for playback.
    Device is being used by another application.
    Additional debug info:
    gstalsasink.c(697): gst_alsasink_open (): /GstPipeline:pipeline0/GstAlsaSink:alsasink0:
    Device 'default' is busy
    Setting pipeline to NULL ...
    Freeing pipeline ...

Can anyone suggest me what to do for the target side since PC side, alsasink is perfect.
