Unfortuantely, moving this doesn't suffice.  There is the hibernation
resume that needs the explicit initialization again.

Also, calling this in alc_alloc_spec() isn't intuitive.  Although it'd
become a larger patch, I prefer making it more explicit, e.g. creating
alc_pre_init() function handling the pre-init procedure and call it
from appropriate places.

So I can imagine a patch like below.  Does it work for you?


thanks,

Takashi
