SDL_SetAudioStreamGain sets stream's gain, but SDL doesn't take it into account (SDL 3.2)

[Tsukulimer]

SDL 3.2 simple-playback.c from examples directory
To test it I just added this code after stream creation

    if (!SDL_SetAudioStreamGain(stream, 0.0f))
    {
        return SDL_APP_FAILURE;
    }

It returns true and SDL_GetAudioStreamGain returns 0, but I still can hear sine wave at full volume

Debian 12, tried with SDL_AUDIODRIVER=alsa , SDL_AUDIODRIVER=pulseaudio and SDL_AUDIODRIVER=pipewire

yeah im digging through the SDL source code and im not sure why gain would be applied inconsistently the actual gain it's using is always correct but it's sometimes applied twice, and sometimes applied not at all (which was the original issue i noticed with a 44100 audio -> 48000 device conversion)

FWIW it works as expected if audiospec.format is SDL_AUDIO_S16 instead of SDL_AUDIO_F32
