Audio-tone output device

[dracula78]

When using CMdaAudioToneUtility::PrepareToPlayTone(...) the tone is played through the "external" public speaker.
When using CMdaAudioToneUtility::PrepareToPlayDTMFString(...) the tones are played through the "internal" ear speaker.

1) Is there any way to control this? I need to play a tone through the ear speaker.

2) Does anyone know the meaning of all the bits of the priority bitmask used in CMdaAudioToneUtility::SetPriority(...) ? The API only mentions 4 possible values, but when using the Audio Proxy Server, you need stuff like 0x05220001.

3) Wth is a fixed (pre-defined) tone sequence? Where do they come from? CMdaAudioToneUtility::FixedSequenceCount() returns 0 on my device.

The audio routing has been broken as long as I can remember, thus you can not really control where the audio is played to.

That renders the whole thing pretty useless...
Any idea about the priority bit flags?

Also, when trying to play a tone while streaming (full-duplex) audio I get an error -21 "Access denied" in MatoPlayComplete(). What does this mean? Should I start guessing priority flags, or is that unrelated? I can play tones in my test project without a problem, well, except for the random choice of output device.

Existing forum threads about the predefined sequences, like this (2002) and this (2004), seem to confirm this is loooong forgotten API.

have you added the capability for Full-duplex?
