I tried to apply patch but unfortunately mplayer still complain:
[AO_ALSA] alsa-lib: pcm_hw.c:1578:(snd1_pcm_hw_open_fd) USER_PVERSION failed
[AO_ALSA] alsa-lib: pcm_dmix.c:1092:(snd_pcm_dmix_open) unable to open slave
[AO_ALSA] Playback open error: Inappropriate ioctl for device
this is 32-bit mplayer/qemu-i386 on top of 64-bit kernel (x86_64)
