Jan Schmidt 7994f64006 sunaudio: Fix switch setting on some devices. Add debug. Fix a FIXME.
Fix the setting of toggle switches on some broken audio drivers which
report that no audio ports are settable by ignoring the mod_port field
there.

Add some debug statements.

Fix a FIXME now that Good relies on a new enough gst-plugins-base.
