Audiokit -> No more effects with "kit.pinVolumeDown(); and kit.pinVolumeUp();"

[TangerineDreamer]

I tried today the new update of arduino-audiotools with the new "arduino-audio-driver" library,
but can no more decrement or increment the volume using,

void down(bool, int, void*) {
  kit.pinVolumeDown();  
}  

void up(bool, int, void*) {
   kit.pinVolumeUp();
} 
... 
kit.addAction(kit.getKey(5), down);
kit.addAction(kit.getKey(6), up);

my setup is (off, on, on, off, off) with AudioKitEs8388V1,tried with AudioKitEs8388V2 but gives no soud at all.
The problem goes with headphone as well with the amplified output for HP.

here's the complete sketch i use:

#include "AudioTools.h"
#include "AudioLibs/AudioBoardStream.h"
#include "AudioLibs/AudioSourceSD.h" // or AudioSourceIdxSD.h
#include "AudioCodecs/CodecMP3Helix.h"

const char *startFilePath="/";
const char* ext="mp3";
AudioSourceSD source(startFilePath, ext, PIN_AUDIO_KIT_SD_CARD_CS);
AudioBoardStream kit(AudioKitEs8388V1);
MP3DecoderHelix decoder;  // or change to MP3DecoderMAD
AudioPlayer player(source, kit, decoder);

void next(bool, int, void*) {
   player.next();
}

void previous(bool, int, void*) {
   player.previous();
}

void startStop(bool, int, void*) {
   player.setActive(!player.isActive());
}

void down(bool, int, void*) {
  kit.pinVolumeDown();
  
}  
void up(bool, int, void*) {
   kit.pinVolumeUp();
}  

void setup() {
  Serial.begin(115200);
  AudioLogger::instance().begin(Serial, AudioLogger::Info);

  // setup output
  auto cfg = kit.defaultConfig(TX_MODE);
  // sd_active is setting up SPI with the right SD pins by calling 
  // SPI.begin(PIN_AUDIO_KIT_SD_CARD_CLK, PIN_AUDIO_KIT_SD_CARD_MISO, PIN_AUDIO_KIT_SD_CARD_MOSI, PIN_AUDIO_KIT_SD_CARD_CS);
  cfg.sd_active = true;
  kit.begin(cfg);

  // setup additional buttons 
  kit.addDefaultActions();
  kit.addAction(kit.getKey(1), startStop);
  kit.addAction(kit.getKey(4), next);
  kit.addAction(kit.getKey(3), previous);
  kit.addAction(kit.getKey(5), down);
  kit.addAction(kit.getKey(6), up);


  // setup player
  player.setVolume(0.5);
  player.begin();

  // select file with setPath() or setIndex()
  //player.setPath("/ZZ Top/Unknown Album/Lowrider.mp3");
  //player.setIndex(1); // 2nd file

}

void loop() {
  player.copy();
  kit.processActions();

}

Have i missed something or done something wrong?

I did that because the key5 and key6 did not respond correctly,one gives me a mute and the other the max volume
without any steps between,so i tried to use steps for volume control

[pschatzmann]

To increase the volume you would need to do something as follows:

void up(bool, int, void*) {
  kit.setVolume(kit.getVolume()+0.1);  
}

Ok,it seems to be quite different as before :)
thank you i'll give a try

[pschatzmann]

Yes, but it has the advantage, that you can decide on the step size
