That's weird.
Did you try enable_msi=1 module option, BTW?
Just tried now. The interrupts started flowing and, tada, jack sense works!
Thanks, Takashi, that solves it for me. Is there a way to automate this in the driver for the other less technically inclined users?
Well, as I mentioned, it's basically a bug in the lower layer like ACPI or BIOS. So, the best is to fix them. Using MSI is a kind of workaround, and I'm wondering whether this is specific to your device or in general with other HP dv4, since I didn't hear of the similar bug reports.

Weird indeed. Actually I had already reported this behaviour, see
http://article.gmane.org/gmane.linux.alsa.devel/59809
So far I have not been able to get the interrupts at IRQ22. They still occur at IRQ20. However the problem is hidden when using boot options irqpoll or noapic.
This is not a hardware or bios problem, as the sound is correct on Windows.
Initially I was using kernel 2.6.27 and alsa-driver 1.0.19, currently using kernel 2.6.29 and alsa-driver 1.0.20 with the same behaviour.
I have tried numerous modprobe options. Currently I am using :
alias snd-card-0 snd-hda-intel options sound slots=snd-hda-intel options snd-hda-intel model=hp-m4 enable_msi=1 bdl_pos_adj=32 probe_mask=0x1ff
As Gustavo seems to have succeeded, can he post kernel and alsa-driver versions, boot parameters and modprobe parameters ?
Thanks in advance

Ah, OK, then it's really machine-specific.
So far I have not been able to get the interrupts at IRQ22. They still occur at IRQ20. However the problem is hidden when using boot options irqpoll or noapic.
Did you report it to kernel bugzilla or ACPI guys?
This is not a hardware or bios problem, as the sound is correct on Windows.
It could be still a BIOS issue. Windows (and Linux as well) have tons of workarounds for broken BIOS.
Initially I was using kernel 2.6.27 and alsa-driver 1.0.19, currently using kernel 2.6.29 and alsa-driver 1.0.20 with the same behaviour.
... since the problem is basically independent from the sound driver. It's an IRQ assignment problem, thus a deeper level than what the device driver can manage.
