Alsa Crashes for 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. I can play wav file on my board using aplay utility and can hear sound on speaker connected to Audio Board as well.

When I try aplay -D with multiple hw:0,.... options and 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?

I am attaching the devices list for your reference. (alsa_devices_list.txt)

Please guide to resolve this crash issue. Actually another library (portaudio) is dependent on alsa-lib. Attaching debug for the crash of the portaudio library for reference (patest_sine8_alsa_1_1_0.txt). From debug it could be seen that when it tries to access hw:0,5 it crashes. Please let me know in case of any additional information required from my end.

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