[alsa-devel] 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,

This message is irrelevant from your problem.

If replacing the sound driver code doesn't fix, it means the problem is rather in the video-driver side. Better to ask video guys.

It turned out that radeon driver changed the default parameter value since 3.0 kernel by some reason. Now HDMI audio is disabled in the video driver as default. For enabling, pass radeon.audio=1 module (or boot) option.

It works with radeon.audio=1.
Thank you!
