I updated two patches:
 http://www.netbsd.org/~isaki/audio2-20190402-vcaudio.diff
  - fix build error.
 http://www.netbsd.org/~isaki/audio2-20190414.diff
  - audio layer's bug fix.
  - patch for vidcaudio(4), harmony(4).

Status updates: (thanks tsutsui-san, ebijun-san and macallan@!)
 + works (without patch): audiocs(4), autri(4), wss(4)
 + works (need a patch): dbri(4), yds(4)
 + compiled but not tested: vcaudio(4), vidcaudio(4), harmony(4)

Old interface compatibility works well (than I thought :),
so some drivers may work without modifying.

If there is no objection, I'll commit it next weekend or later.
Thanks,
