Question:
I have been trying to play and record audio at the same time and have found no device that supports this. Is this supported
on Symbian OS in any version or device ?
Answer:
The Symbian OS reference design does not support full duplex audio because the audio policy has been designed to be simple
'one-shot' audio playback / recording i.e. only one application will have any audio at any time. This policy is in the non-standardised
part of the audio subsystem DevSound and so phone manufacturers are able to include full duplex audio in their own designs
if they wish.
At present only the 6630 (based on Symbian OS 8.0a) has included a full duplex audio policy. This is, however, restricted
and has to be initialised into full duplex 'mode' via a proprietary request. In order to obtain the information on how to
do this, 3rd parties are advised to speak directly to Nokia who may be able to release this information.
