Seems that the lame ! mad part creates discontinuites.

The folowing command show no discontinuities:
> GST_DEBUG=2 gst-launch -v filesrc location=alien.mpg ! decodebin2 ! audioconvert ! audiorate ! identity check-perfect=1 silent=1 ! lame ! mad ! alsasink

But if we check for discontinuites after the mad decoder with the command:
> GST_DEBUG=2 gst-launch -v filesrc location=alien.mpg ! decodebin2 ! audioconvert ! audiorate ! lame ! mad ! identity check-imperfect-timestamp=1 check-perfect=1 silent=1 ! alsasink

The log show:
