What is your platform? Which image were you playing? And what kind of error did
you meet?(hang, or just no audio output?)

Could you please attach results of below commands to help us isolate your
issue:
1) aplay -l
2) cat /etc/modprobe.d/alsa.conf
3) if MID Intel HDA is indexed 0, how about "aplay -D plughw:0
/usr/share/sounds/alsa/Front_Center.wav"?
