I don't know if this concerns my situation ( http://mailman.alsa-project.org/pipermail/alsa-devel/2009-June/018262.html ) or not..
headphones work for me, front speaker work but LFE doesn't and the Irq22 stays on 0 too
# cat /proc/interrupts | grep '22:' 22: 0 0 IO-APIC-fasteoi uhci_hcd:usb6, HDA Intel
Takashi told me to play with hda-analyser and hda-verb though I don't what to do with hda-verb and I don't if what hda-analyser showing me is the current situation or the desired one..
Thanks
So it looks like this a general situation on this hardware.
If you get sound, at least from the front speakers, without the IRQ22 being triggered, what are your kernel and alsa versions, your boot parameters and alsa (modprobe) parameters ?
I have no knowledge about the hda-verb, etc. so I am not to help you much in this area.
