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* :
Playing WAVE '/data/Haze.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Mono
