Is it possible to increase maximum loudness? Project work well but it produces very low volume despite increase host volume to max.

I added multiplier in bt_app_core.c . The loudness is increase as intention.

for (int i=0; i<item_size/2; i++) { int32_t temp = (int32_t)(pcmdata); temp = temp s_volume 4; // add multiplier here temp = temp/512; //pcmdata = ((pcmdata)s_volume)/127; *pcmdata = (int16_t)temp; pcmdata++; }
