Hi all:


I was using autaudiosink and appsrc as my sink and src. A usb earphone was
used as output device. The problem was: when I detected the plugging out of
the usb earphone, I called gst_element_set_state(pipe, GST_STATE_NULL). Then
the function blocked and did not return.

Do you have any suggestions?
