it seem use_planar(rec) is false as pulseaudio log 

D: [pulseaudio] alsa-util.c: Trying a52:0 with SND_PCM_NO_AUTO_FORMAT ...
D: [pulseaudio] alsa-util.c: Managed to open a52:0
D: [pulseaudio] alsa-util.c: snd_pcm_hw_params_set_access() failed: Invalid
argument
D: [pulseaudio] alsa-util.c: PCM seems to support non-interleaved access, but
PA doesn't.
