No sound with HDA ATI HDMI since kernel 3.0

Hello,

First, I'm sorry for my english is awkward and I'm not sure if I'm at
the right place.

I use Linux amd64 and have two sound "cards":

Motherboard:
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfe9f8000 irq 47
Graphic card:
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfeaec000 irq 48

(lspci ouput and alsa-info.txt attached)

I have no problem with 2.6.39.3.
With kernel 3.0 and 3.0.1, I have no sound with HDMI output.

VLC 1.1.3 gives me no sound (I don't see any error message).
MPlayer SVN-r31918 (with correct -ao alsa:device=hw=1.3 option, it
works with 2.6.39.3) gives me no sound and I see the audio position in
seconds on status line going approximatively 6 times faster than normal
(in fact, video is 6 times faster, too).

I attached dmesg output for kernels 2.6.39.3 and 3.0.1.

For both kernels, I have the line
	hda-intel: IRQ timing workaround is activated for card #1.
	Suggest a bigger bdl_pos_adj.

I tried modifying parameters bdl_pos_adj and position_fix, because I
read that some people tried this, when I searched for this problem, but
only 2.6.39.3 worked, with default setup (see attached tests.txt file).

I also tried to replace the files in sound/pci/hda/* from 2.6.39.3 (I
read that about Debian bug 635362 in this very list) but it doesn't work
better.

I'm only a modest user and I don't know what to do best, but I would be
delighted if I could help to solve what I believe to be a bug on a
specific hardware.

Cordially,
--
