Description
Audio clips seem to have a slightly lower volume when played through the QMediaPlayer than when played through the QSoundEffect class (1~2 dB difference, depending on the sound effect).
The differences in system gain applied on the audio signals: When using the QMediaPlayer, ~x1.8 gain is applied, whereas with QSoundEffect, ~x2.6 gain is applied.
The issue is happening when using the ffmpeg backend.
