Something about only pausing on PCM buffer boundaries ... I can hunt
through the messages in the archives and post again if it'll help.

Does this mean the decoder is decoding about 4 seconds ahead of
realtime? Let me try to give some examples of when this occurs:
* Scroll through a menu fast. Notice that although you might have
skipped items 2, 3 and 4, the voice UI still plays those clips; they
aren't silenced.
* With file name spelling enabled, move through the file browser. This
is when the issue is a huge problem; you have to wait for the voice UI
to spell several file names before it catches up.
* Go to the Info->Rockbox Info menu item, then exit. The voice UI will
take about 4 seconds to 'catch up'.

Thanks again.
