Audio routing - Belle FP1

[vh2]

Hi all,
We have written a VoIP application.
For audio playback / recording we are using VoIPAudioServicesAPI_v2.4.0
class CVoIPUtilityFactory etc.
from LIBRARY VoIPAudioIntfc.lib.


To route the Audio to handset or loudspeaker, we are using
class CTelephonyAudioRouting
LIBRARY TelephonyAudioRouting.lib

In Symbian^3 Anna and Belle this works fine.
But in Belle FP1 it is not possible to change audio routing to loudspeaker.

CTelephonyAudioRouting::AvailableOutputs()
retunrs on all versions

[0]=0 //ENotActive
[1]=1 //ENone
[2]=3 //ELoudspeaker
[3]=2 //EHandset

The call to
CTelephonyAudioRouting::SetOutputL(CTelephonyAudioRouting::ELoudspeaker);
completes without error

But on Belle FP1 the call back
MTelephonyAudioRoutingObserver::SetOutputComplete()

will not be called and output is still routed to handset.


Any Ideas what’s wrong in Belle FP1?

Thanks in advance

Basically APIs not included in public SDKs do not have any compatibility promise what so ever, so could be that the API has changed with Belle FP1, I suppose if you can not figure ways on fixing it, you could always try paid technical support.

In Belle FP1 we can use
CVoIPAudioDownlinkStream::SetAudioDevice(ELoudSpeaker)
This API was broken on Symbian^3 Anna

HI,

Could any one tell me how to do this, I want to make a call and after that a song (from a file) will be given as an input (not played) to the speaker of the mobile, so that from the other side the song can be heard, but nothing can be heard here. Which classes will allow me to get hold of the speaker and give input raw sound data. Thanks.

You could search this forum with keywords like uplink for older discussions on playing audio to the phone line. Its not trivial thing, and implementation differs between platform versions.
