	the reason is that decodebin links to the first pad created by qtdemux
(which is probably video in your case). You can try

gst-launch playbin uri=file:///home/Dell.mp4

If your really want to try decodebin, then no qtdemux is needed 

gst-launch filesrc location=/home/Dell.mp4 ! decodebin name=d \
           d. ! alsasink  \
           d. ! xvimagesink

or better

gst-launch filesrc location=/home/Dell.mp4 ! decodebin name=d \
           d. ! audioconvert ! alsasink  \
           d. ! ffmpegcolorspace ! xvimagesink

This will connect both decodebin pads (audio and video) to appropriate
sinks. 

	Best regards,
