This is very interesting for me, as I have another HP dv4
computer with the same sound chip, and I get roughly
similar results, but with a significant difference (using
Tagashi's snapshot from yesterday) :

HDA Intel 0000:00:1b.0: power state changed by ACPI to D0
HDA Intel 0000:00:1b.0: PCI INT B -> GSI 22 (level, low) -> IRQ 22
hda_intel: codec_mask forced to 0xff
HDA Intel 0000:00:1b.0: setting latency timer to 64

The point is I never get an IRQ 22, I get IRQ 20 instead,
so most players do not work unless I boot with irqpoll or
noapic options (mplayer is ok though)

Now, you get the IRQ 22 routed by APIC from PCI INT A,
whereas I have the IRQ 22 routed by APIC from PCI INT B.

And I have the PCI INT A routed to IRQ 20 for USB :

ehci_hcd 0000:00:1d.7: PCI INT A -> GSI 20 (level, low) -> IRQ 20
ehci_hcd 0000:00:1d.7: setting latency timer to 64
ehci_hcd 0000:00:1d.7: EHCI Host Controller

 From this I conclude that both our sound chips trigger INT A,
but in my case, it is wrongly the INT B that has been connected
to IRQ 22.

So my question to all the techies on this list : how on earth can
I influence on this IRQ routing ?
