I have introduced a typo in the debug category. It's GST_DEBUG="*SCHED*:6" (see
the second *). The second * is needed since the debug category name is
GST_SCHEDULING . Again, remove -v and ignore last-message, those are racy and
does not represent the reality for your test.
GST_DEBUG="*SCHED*:6" \
gst-launch-1.0 alsasrc device=hw:0,0 ! fakesink name=digitial \
alsasrc device=hw:1,0 ! fakesink name=ANALOG \
2>&1 | grep calling | head -n 30
