how to get inno pi DAC hat working

 I'm using a headless raspberry pi

firstly type: alsamixer and press f6 - you will see the hat is not there.

enable the hardware..

sudo nano /boot/firmware/config.txt

enter

dtoverlay=allo-boss-dac-pcm512x-audio

(from How to set up Allo BOSS DAC hat for your Headless Raspberry Pi | How To Hi-Fi)

reboot..

check your devices..
aplay -l

you can see here that deivce is card 1, device 0

card 1: BossDAC [BossDAC], device 0: Boss DAC HiFi [Master] pcm512x-hifi-0 [Boss DAC HiFi [Master] pcm512x-hifi-0]

now we make it default

sudo nano /etc/asound.conf

then enter

pcm.!default { type hw card 1 } ctl.!default { type hw card 1 }

sudo reboot

sudo raspi-config

system, audio, 1 BossDAC

install mplayer

sudo apt-get update

sudo apt-get install mplayer
