LyraT crashing when Volume reaches 0.6

[pete-789]

This is a LyraT 4.3 board, the code is basically the hls-buffer-i2s.ino example modified to include a volume control controlled by an IR receiver. I get the stream okay through the speakers, and IR codes are received fine.

I'm starting the volume at 0.3 and incrementing (or decrementing) it by 0.1, min of 0, max of 1. The volume does increase (or decrease) but the board crashes and reboots when the volume reaches 0.6. It does this every time.

If I uncomment vcfg.allow_boost = true; and run the program the board crashes and reboots straight away.

I hope I have the code right:

// IR
#define DECODE_NEC   
#include "PinDefinitionsAndMore.h"
#include <IRremote.hpp> // include the library

// audio-tools
#include "AudioTools.h"
#include "AudioTools/AudioCodecs/CodecHelix.h"
#include "AudioTools/AudioCodecs/CodecMTS.h"
#include "AudioTools/Communication/HLSStream.h"
#include "AudioTools/Concurrency/RTOS.h"
#include "AudioTools/AudioLibs/AudioBoardStream.h"

float vol = 0.3;

// AudioBoardStream out(AudioKitEs8388V1);  // final output of decoded stream

AudioBoardStream out(LyratV43);  // final output of decoded stream
VolumeStream volume(out);

// I2SStream out;  // audio output

BufferRTOS<uint8_t> buffer(0);
QueueStream<uint8_t> queue(buffer);
HLSStream hls_stream("secret", "secret");  // audio data source
// decoder
MP3DecoderHelix mp3;
AACDecoderHelix aac;
MTSDecoder mts(aac);             // MPEG-TS (MTS) decoder
MultiDecoder multi(hls_stream);  // MultiDecoder using mime from hls_stream
// EncodedAudioOutput dec(&out, &multi); // changed for VolumeStream below
EncodedAudioOutput dec(&volume, &multi);

// 2 separate copy processes
StreamCopy copier_play(dec, queue);
StreamCopy copier_write_queue(queue, hls_stream);
Task writeTask("write", 1024 * 8, 10, 0);

// Arduino Setup
void setup(void) {
  Serial.begin(115200);

  IrReceiver.begin(12, DISABLE_LED_FEEDBACK);    

  AudioToolsLogger.begin(Serial, AudioToolsLogLevel::Warning);

  // get the board config
  auto config = out.defaultConfig(TX_MODE);

  // set initial volume
  auto vcfg = volume.defaultConfig();
  vcfg.copyFrom(config);
  // vcfg.allow_boost = true; // activate amplification using linear control
  volume.begin(vcfg); // we need to provide the bits_per_sample and channels
  volume.setVolume(vol);

  if (!hls_stream.begin(

    stop();

  // register decoders with mime types
  multi.addDecoder(mp3, "audio/mpeg");
  multi.addDecoder(aac, "audio/aac");
  multi.addDecoder(mts, "video/MP2T");  // MPEG-TS

  // start output
  auto cfg = out.defaultConfig(TX_MODE);
  // add optional configuration here: e.g. pins
  out.begin(cfg);

  buffer.resize(10 * 1024);  // increase to 50k psram
  dec.begin();               // start decoder
  queue.begin(100);          // activate read when 100% full

  writeTask.begin([]() { copier_write_queue.copy(); });
}



void loop() { 
  
  copier_play.copy(); 

  if (IrReceiver.decode()) {

      if (IrReceiver.decodedIRData.flags & IRDATA_FLAGS_IS_REPEAT) {
        IrReceiver.resume();
      } else {
        switch (IrReceiver.decodedIRData.command) {
            case 0x7:
              Serial.println(F("Vol-"));
              if (vol > 0) {
                vol -= 0.1;
                Serial.println(vol);
                volume.setVolume(vol); 
              }
              break;
            case 0x15:
              Serial.println(F("Vol+"));
              if (vol < 1) { // 0.5
                vol += 0.1;
                Serial.println(vol);                
                volume.setVolume(vol);
              }
              break;
        }
        
        IrReceiver.resume();

      }
  }

}

Any ideas and/or guidance much appreciated.

I've had trouble getting log information, as recommended I've been running it at Warning, and there is an awful lot of output at Info level.

If I set AudioToolsLogLevel::Info the sound breaks up but I can raise the Volume further (to a point).

Boot with AudioToolsLogLevel::Info

A couple of hints:

• Log your available RAM: Wifi and codecs use a lot of RAM and you might just run out of available RAM
• Analyze the backtrace that should show you what line of code is causing the issue

Try to remove the Task writeTask("write", 1024 * 8, 10, 0); to double check that this is not your source of trouble...

[pete-789]

Ah, thanks... I have no idea how to do either of those things, so a-googling I go!

[pete-789]

Actually it is not just Volume but after a number of any keys that I'm translating pressed on the IR remote control.

RAM seems fine, and there is no backtrace - the board just reboots. I think this might just be the strange character and usage of Pin 12.

So... I'm trying Pin 13 (with DIP switch 4 ON this maps to the JTAG header MTCK). As per the Espressif Hardware Ref, this pin is used for

JTAG MTCK, MicroSD D3 and Audio Vol- (TP)

I can switch off the SD integration with sd_active = false; - thanks for the tip!

Is it possible to switch off button integration? Presumably you have the Audio Vol- (TP) button already mapped to Pin 13 on the LyraT 4.3, which could be why I'm getting

E (4216) gpio: gpio_pullup_en(78): GPIO number error (input-only pad has no internal PU)
E (4217) gpio: gpio_pullup_en(78): GPIO number error (input-only pad has no internal PU)
Warning: Pin '13' not set up because of conflict

(I can use the IR receiver fine on Pin 13 in a simple program).

[pschatzmann]

Did you try if you can reproduce the issue w/o using tasks ?

[pete-789]

Thanks for the reply Phil.

I hope this is what you meant, I slowly added in lines of code until the error happened, it is the line

out.begin(config); // <<<<<<

the error is

E (4213) gpio: gpio_pullup_en(78): GPIO number error (input-only pad has no internal PU)
E (4214) gpio: gpio_pullup_en(78): GPIO number error (input-only pad has no internal PU)

here is code

I am getting these errors as well: this has no impact and can be ignored...
AudioBoardStream has automatic key support, I2SCodecStream has not key support.

[pete-789]

Ah, many thanks, I2SCodecStream might be what I need then.
