Alsasrc is a livesrc. I notices the same problem, but have not looked into it.
Would be cool to make small standalone test case for it, file a bug and attach
the test-case.
Btw. what project are you working on?

Again, having a small test case would rock. gst-plugin-base has
"tests/examples/dynamic/" directory with some dynamic pipeline tests. We could
