Comment(by chia-hsiu):

 I original think it may caused by different insert technique, but after
 continue test 10 times loopback without inserting loopback, it still have
 failure.[[BR]]
 Test with svn head 3416.[[BR]]

 {{{
 dev /audio
 patch noop acoustic-test automatic-test
 patch noop connect-loopback loopback-test
 patch noop disconnect-loopback loopback-test
 dend
 1 to test-station
 diag-mode
 test /audio
 }}}
 test 10 times manually.
