From looking at the code for al_create_voice it seems only
driver_allocate_voice should modify the frequency. So is it ok to
just update the voice parameter from that function?<br>

Which function in the audio driver is allowed to do this? And
is it as simple as<br>
<br>
void driver_allocate_voice(ALLEGRO_VOICE * voice){<br>
voice->frequency = 44100; // driver only supports 44100<br>
}<br>
<br>
I don't see any existing drivers modifying the voice's
frequency. It is highly unlikely that most of the drivers
support arbitrary frequencies.<br>
