We are developing a PTT client for the 3rd Ed. FP2 platform, based on pjsip, and have run into the problem that the volume of the audio is too low We route the audio to the loudspeaker and we have tried both the VoIP Audio Services API and Mda (CMdaAudioOutputStream) for reproducing the audio, but the result is the same: the volume level is so low that you have to hold the phone close to the ear in order to hear what is said. We set the volume to the value of MaxVolume(). For the Mda case, the priority is set up like this:
but I don't know if the priority has any influence on the volume level?
Does anybody know how we could get a higher volume level?
