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,
