Original commit message from CVS: * tests/icles/.cvsignore: * tests/icles/Makefile.am: * tests/icles/test-oss4.c: (opt_show_mixer_messages), (WAIT_TIME), (show_mixer_messages), (probe_mixer_tracks), (probe_pad), (probe_details), (probe_element), (main): Small oss4 test that probes for available devices and retrieves their caps and mixer tracks and all that. Also allows testing of mixer change messages on the bus.
