Non-root user aplay has no sound in jetson nano

[wly]

Hi,nvidiia:
When playing audio as a non-root user, there is no sound. The alC5639 sound card is used?
aplay cmd:

wly@linux:~$ aplay -D plughw:CARD=tegrasndt210ref,DEV=0 16.wav
aplay: main:788: audio open error: Device or resource busy

aplay -l log:

wly@linux:~$ aplay -l
