[alsa-devel] question about aplay fails on arm 64

[曹能华]

Hello, alsa maintainer:



    Recently, i encounter aplay failed on arm 64 bits core. My test
environment is: Linux kernel use arm 64 bits, and alsa-lib/aplay is 32 bit
version. So the ioctl interface should use snd_pcm_ioctl_compat. but when i
use aplay to playback music, i encounter "aplay" segment fault. Do we need
some special configuration for alsa-lib/aplay to support 64 bit kernel? Any
suggestion will be appreciated. Thanks!
