Changes (by dsd):

  * component:  kernel => ofw - open firmware


 Reproduced on svn head (r2584).

 Bisecting tracked this down to r2072 being the cause: "close audio device
 after playing startup sound so subsequent test /audio works right (resets
 the sample rate)" (#10521).

 It is strange how the problem only appears in the secure boot path, not
 unsecure mode.

 While looking at this I am reminded of a similar XO-1 issue that was fixed
 in r880. That commit might be a good memory-jogger for XO-1 audio related
 stuff (or perhaps its unrelated).
