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!
