HDMI 10" LCD Screen Kit Audio

hi there,

i’m building a batocera pc with this screen everything works accept for the sound which worked before i connect this screen. i think its trying to send the audio over HDMI but i have no idea if i can somehow connect speakers to the pcb.

can anyone tell me if thats possible or point me to a manual for this ?


im using twister os on a 7 inch screen and use a usb sound card and a small speaker until i find a speakerphat and i have a picade 8 inch and when i use the twister os it uses the picade x hat as a mono dac hat for sound
