aplay crashes on ARM

[Arjav Parikh <parikharjav24@xxxxxxxxx>]

Hi,

I am using linux on APQ8053 SOC with alsa-lib v1.1.0. I have ZL38063 sound card  connected with APQ8053 over I2S.

When I try aplay -D with multiple hw:0,.... options, below are the observations:

aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear sound on speaker.

aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav - File does not get played and observe below output.

aplay -D hw:0,5 /data/Haze.wav - Segmentation fault

Why I do get segmentation fault when executing aplay -D hw:0,5 /data/Haze.wav?

aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav Output :
