Nakajima-san,

Arigatou gozaimashita.

I got as far as you did regarding channel layout (i.e., converting from the
positions array as used in 0.10 to the channel-mask as used in 1.0). I just
spent some time looking at it, I think I finally understand it.

Sebastian was pointing you in the right direction. The code from osxaudiosink.c
that calls gst_core_audio_audio_device_get_channel_layout() and then iterates
over the results to build a position map needs to move out of osxaudiosink.c
and into the osxaudioringbuffer.c's acquire function. Once you have constructed
that position map, you can call the ring buffer's set_position function.

If that makes sense to you and you are comfortable implementing it, please give
it a try. Otherwise I can put together a patch for you to review.

Yoroshiku!
