alsa-project/alsa-utils issue #119 was opened from MT-LeiZhao:

Hi guys, I'm a new guy for audio driver. I have added logs in my ko which have the pcm function. I can see the normal call stack log using pulseaudio. But I can't see any log about my driver through aplay. I guess there was something wrong in aplay. Can anyone tell me how to get the detail log for aplay? Thank you very much~~~
