llm-audio ignores playVolume setting from clients

[nyasu3w]

Environment: StackFlow v1.4.0 and M5Module-LLM dev branch

The playVolume setting is not available from M5Module-LLM library on arduino.
The below code makes no effect.

    /* Setup Audio module */
    M5.Display.printf(">> Setup audio..\n");
    m5_module_llm::ApiAudioSetupConfig_t audio_config;
    audio_config.playVolume = 0.01;  
    module_llm.audio.setup(audio_config);

When I changed the value of "volume" of "play_param" in /opt/m5stack/share/audio.json, the volume got quietter as expected. So I doubt that the volume setting from json might not be implemented in v1.4.0.

The playVolume parameter is obsolete in StackFlow 1.3 and later versions. Use json for configuration instead.

Oh, it is obsolete. How do I change volumes of awake_wav(kws) and tts?

[Abandon-ht]

Modify the value of volume in the play_param item in the /opt/m5stack/share/audio.json file.

Before calling the audio unit, you can use the following:

{
    "request_id": "1",
    "work_id": "audio",
    "action": "setup",
    "object": "audio.play",
    "data": {
        "volume": 0.5
        }
}

Initialize the audio module to dynamically configure the volume.

Thanks for good information.
My understanding is that "playVolume" is renamed to "volume", and it is not imeplemented yet in M5Module-LLM library.
(And it seems that more configurations are supported in llm_audio by CONFIG_AUTO_SET macro.)
