Hi guys,
I'm trying to debug a problem on the D2 port whereby playback doesn't start
until the audio buffer is completely filled for the first time - ie. when
'alloc' reaches full, a few seconds after starting playback from the file
browser.
I've narrowed it down to the 'if' condition in pcmbuf_play_start() at
pcmbuf.c:517. This function is called twice in quick succession when playback
is started, but both times 'pcmbuf_unplayed_bytes' and 'pcmbuf_read' seem to
have the value 0, therefore the condition fails and pcm_play_data() is never
called.
Only when the audio buffer fills completely does a further call to
pcmbuf_play_start() occur, and only at this stage is the 'if' condition
satisfied.
Unfortunately my knowledge of the pcmbuf code is next-to-zero, so I don't
know where to look next. Any pointers would be most appreciated!
Note that this is only happening for normal audio playback - voicing seems to
work correctly in all cases.
Cheers,
Rob.
