Hello!
I has a problem on my Acer laptop with azalia. The HDA controller
did not generate interrupts. And i heard the infinite looping sound.
The reason of this is that the laptop BIOS always set the D3 power state
for HDA controller during the boot time.
This patch solved my problem. The second part of patch enable beep for
my laptop.
