Sorry, I don't understand this bug report. Could you describe in more detail what you think the bug is, and how it relates to audiokaraoke?

If the volume level is different for headphones and loudspeaker that sounds more like a speaker volume / mixer setting issue?

We need to Eliminate the human voice in a song, so we use "audiokaraoke" and set the property "level", "filter-width" to do it. you will see my function：
- (void)setRemoveVoice:(BOOL)remove {
    if (self->pipeline == NULL)
        return;
   
    float level = remove ? 1 : 0;
    g_object_set(self->audiokaraoke, "level",level, NULL);
}
     l call this function after song playing, it is successful to Eliminate the human voice when Connecting Headphones. However, Pull out the Headphones and use the loudspeaker to play the song it was no sounds anymore. l want ask about the reason.(Hardware without any problems)
