[alsa-devel] How ALSA handle PCM playing when the ALSA modules are removing

[Zhu, Yingjiang]

Hi, Takashi

         I am doing an ALSA module test with insert module/remove module 
loop, when playing a wave during this loop, there will be kernel oops. 
Does ALSA need handle this case? Or just forbid wave playing during the 
module load/unload?

         If this need to be handled, module unload will wait the wave 
play ending, or just stop the wave play at the first of the load/unload?
