I'm not sure, but it might be that it has to do with a change
that Slasheri did way before these changes to pcm_record.c
happened, iirc even before recording was implemented for
irivers. Iirc he changed the audio init to happen in the
background, in order to cut a bit on boot time. Maybe we're
seeing a race condition here?

Sorry, I've got no time to check that right now...
