Beep via pcspkr module works fine without your patch - regardless of
current PM state of HDA device; with your patch applied - the beep is
very quiet if HDA is suspended (same as with firmware generated beeps).

pcspkr generated beeps are immune to every mixer/switch setting except
for "Master Mute Switch", which mutes them completely (i.e. they are not
very quiet, they are gone). And again - this is the very same as with
firmware beeps; that would mean that both (firmware's and pcspkr's) are
using PIT to drive "PC Speaker".

Already there by now, thanks!
