I decided to change from 686 to AMD64 architecture after all the
buzz the past few days about the virtues of using the AMD64
architecture. After installing Lenny, I have no sound at all. (with
686, I had sound from the install, no problem).

I've done a good bit of searching in the archives, but as of yet
I've not found a solution.
Thanks in advance,
Mike
Doing more digging, I find I also have this [1] problem (problem #1).
I'm not sure if the two issues are related at all. I have tried
booting with iommu=soft, still no sound.

I may be getting closer to the solution. I did get sound out of the
machine a few minutes ago. I found this entry in /var/log/messages
when the sound was working:
Jan 11 02:04:28 moe kernel: [ 6431.540366] ACPI: PCI Interrupt
0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
Jan 11 02:06:39 moe kernel: [ 6578.403702] hda-intel: Invalid position
buffer, using LPIB read method instead.
After a reboot and trying to use the sound, I see these messages in
/var/log/messages:
Jan 11 02:16:20 moe kernel: [ 354.828388] ACPI: PCI Interrupt
0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
Jan 11 02:16:20 moe kernel: [ 354.858407] ACPI: PCI interrupt for

0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
Jan 11 02:16:29 moe kernel: [ 364.437812] ACPI: PCI interrupt for
device 0000:00:14.2 disabled
Jan 11 02:17:12 moe kernel: [ 410.171457] ACPI: PCI Interrupt

Jan 11 02:17:12 moe kernel: [ 410.203559] ACPI: PCI interrupt for
device 0000:00:14.2 disabled
So it would seem that my sound is not getting (for some strange
reason) an interrupt because it is disabled. Note, nothing was changed
in the BIOS during this reboot.
Thanks for any clues,
Mike
I had a recent update knacker my sound but in a different way.
You want to read the bit on snd-hda-intel in
/usr/share/doc/alsa-base/driver/ALSA-Configuration.txt
try to identify your card and put a line a bit like this in
/etc/modprobe.d/alsa-base
options snd-hda-intel model=6stack-dig position_fix=1
I don't know how much tweaking the Debian team do to ALSA but I've found
the wiki a good place for help, particularly in getting digital output
going
http://alsa.opensrc.org/index.php/Main_Page
Good luck, keep us posted.
Thanks Bob. Yes, I'm aware of the ALSA-Configuration.txt and have tried
several possibilities. I've also read quite a bit on the Alsa site.
Something I'm missing somewhere though. Sound is still eluding me.
Thanks,
Mike
