Dear Anand,

I assume you should be able to have some audible timestamp with this

gst-launch-1.0 audiotestsrc wave=ticks apply-tick-ramp=true
tick-interval=100000000 freq=10000 volume=0.4 marker-tick-period=10
sine-periods-per-tick=20 ! autoaudiosink

This pipeline produces a series of 10 kHz sine wave ticks. Each tick is
20 sine wave periods long, ticks occur every 100 ms and have a volume of
0.4. Every 10th tick is a marker tick and has the default marker tick volume
of 1.0. The beginning and end of the ticks are modulated with the ramp.

Hope it helps.
