Hi,
I am getting difficulty setting up ALSA for my new HP portable computer. lspci displays the audio chip as : Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) and /proc/asound displays the codec as IDT 92HD71B7X
I have uploaded the detailed hardware and configuration parameters to http://pagesperso-orange.fr/b.andre/visits.html/92HD71B7X
I am using Fedora 10 x86_64 without pulseaudio and with the latest alsa-driver : alsa-driver-1.0.18a.16.g4012f.139.g6e583.tar.bz2
I have googled for a similar problem, but did not get to an actual fix, the following thread appears to deal with a most similar situation : http://forums.opensuse.org/pre-release-beta/399731-beta-5-no-sound.html
After several tries, I have set modprobe.conf as alias snd-card-0 snd-hda-intel options sound slots=snd-hda-intel options snd-hda-intel model=hp-m4 single_cmd=1 enable_msi=1
Don't use single_cmd=1 option. If this is needed, it's already something very wrong, most likely a deeper problem like ACPI.

Thank you for your help.
I had already tested without the single_cmd=1 option, and the only difference I see is the " azx_get_response timeout, switching to polling mode" warning.
Switching to polling mode is OK and mostly harmless. But single_cmd is not. There is a VERY big difference between them.
Probably related is the fact that I have never seen an IRQ 22.
from proc/interrupts :
22: 0 0 IO-APIC-fasteoi uhci_hcd:usb6, HDA Intel
Hum, then it must be an interrupt thing. Ask rather ACPI guys.
