I don't think I understand what you mean...
Currently, pcspkr.c just stops the timer
counter to shut up the beep.
snd-pcsp needs more. snd_pcm_suspend_all()
for instance. Since it doesn't register
itself as a platform driver any more, he
have to register itself into pcspkr.c.
Or?
I mean, sending a "shut up" event to the
pcspkr's handler is not what snd-pcsp
needs to do.
