Volume automatically returns to 0 at the start of connection

Hi guys,
I am having a problem on ESP32-A2DP. The volume automatically returns to 0 at the start of connection.
This is may code
#include "BluetoothA2DPSink.h"
BluetoothA2DPSink a2dp_sink;
void setup() {
//Internal DAC config
const i2s_config_t i2s_config = {
.mode = (i2s_mode_t) (I2S_MODE_MASTER | I2S_MODE_TX | I2S_MODE_DAC_BUILT_IN),
.sample_rate = 44100, // corrected by info from bluetooth
.bits_per_sample = (i2s_bits_per_sample_t) 16, /* the DAC module will only take the 8bits from MSB */
.channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,
.communication_format = (i2s_comm_format_t)I2S_COMM_FORMAT_STAND_MSB,
.intr_alloc_flags = 0, // default interrupt priority
.dma_buf_count = 8,
.dma_buf_len = 64,
.use_apll = false,
.tx_desc_auto_clear = false
};
a2dp_sink.set_i2s_config(i2s_config);
a2dp_sink.start("SPEAKER");
}

void loop() {
}

The volume is controlled by the volume on your phone!
