I can create a Player on my 6620 that plays wav OK
from an internal buffer.

However, when specifying an internal buffer of
3gpp data I get various "Symbian OS Error: -xxx" (!).

The same buffer plays fine on a Sanyo Java-capable

I'm specifying 8bit 8000Hz, mono. Is there a certain
combo of bits/hz/channels that is necessary?

If not, I'll have to revert to wav which is horrible because
it is so much larger....
