Original commit message from CVS:
Patch by: Brian Cameron  <brian dot cameron at sun dot com>
* sys/sunaudio/gstsunaudiosink.c: (gst_sunaudiosink_init),
(gst_sunaudiosink_prepare), (gst_sunaudiosink_write):
* sys/sunaudio/gstsunaudiosink.h:
Use spec->segsize and spec->segtotal in the prepare function
to initialise the ring buffer instead of using the buffer-time
property (#337421).
