Fade is not working if sound has current volume equal zero #727

Closed Oldes closed 1 year ago

Oldes commented 1 year ago

This works OK:

ma_sound_set_fade_in_pcm_frames(pSound, 0, 1.0, 44100);

But when the sound first have set volume to zero, the fade is not started.

ma_sound_set_volume(pSound, 0);
ma_sound_set_fade_in_pcm_frames(pSound, -1, 1.0, 44100);

It is most probably because zero volume sounds are skipped from processing, but still, should not it be supported without manually setting the volume to some almost zero value?

Hm... it looks that the fader has separate volume values and the volume set ma_sound_set_volume is not affected by the fader... I wonder how I could change the volume value with a fade?

This is intended behaviour. The two are decoupled like you discovered. There's no built-in way to smoothly change the volume itself.

(Converting this one to a discussion.)
