Hi. I've upgraded from kernel 2.6.34 to 2.6.35 and the beep through the
sound card stopped working. I found a very similar problem[1]
(commit[2]).

[1] http://lkml.org/lkml/2010/7/28/228
[2] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=dc1eae...

I've tried to manually enabling the beep with the steps in the e-mail
thread I found:

# echo -n 1 > /sys/class/sound/hwC0D2/subsystem_id
# echo -n 1 > /sys/class/sound/hwC0D2/reconfig

But it didn't work (the beep still goes through the pcspkr).

I've tried to naively (I'm not a kernel hacker, so I was just guessing) add a
new entry with the quirks beep_white_list by copying the entry for ASUS like
this:

diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c
index 596ea2f..ca3ed12 100644
--- a/sound/pci/hda/patch_realtek.c
+++ b/sound/pci/hda/patch_realtek.c
@@ -5183,6 +5183,7 @@ static void fillup_priv_adc_nids(struct hda_codec *codec, hda_nid_t *nid
 
 static struct snd_pci_quirk beep_white_list[] = {
        SND_PCI_QUIRK(0x1043, 0x829f, "ASUS", 1),
+       SND_PCI_QUIRK(0x8086, 0xd613, "INTEL", 1),
        {}
 };
 
But it didn't work either. Then I noticed, if I'm understanding the source code
(sound/pci/hda/patch_realtek.c) and documentation
(Documentation/sound/alsa/HD-Audio-Models.txt) right, that my card is not
present in the models listing, but it worked fine in 2.6.34 (and previous)
kernel(s).

I would appreciate if somebody can give me some hints on how to get the beep
back.

Thank you.


Here is some data about my card, please let me know (Cc me please) if you need
any other information.

So, you want to hook the beep over codec but it doesn't work, right.
Do you get "Beep" mixer elements and the dedicated input device?

Hm, this should work.  At least, you should have beep mixer & co with

This is no problem.  The model entry is only for special cases.
For normal machines, no quirks are needed.

No, I don't think I have any of them (cat cat /proc/bus/input/devices at the

I didn't know where to find the script, Google gave me this:
http://git.alsa-project.org/?p=alsa-driver.git;a=blob_plain;f=utils/alsa-info.sh
So this is what I've use. I've shared the results at:

Well, my bad, I booted the wrong kernel when trying the patch. The patch
works correctly, so I'll be very glad if it hits Linus kernel soon :)

I could send you the patch but I don't know exactly what to put in the

OK, thanks for the help.

I hope the patch is committed into the main kernel soon.

I can add such a trivial patch manually, of course.  But I'd need
to know which machine you have (vendor/model name, etc).


thanks,

OK, it's fine, I just wanted to be sure that it's no other brand.
The fix is now applied to sound tree, and will be included in the next
pull request, then will reach to stable tree.
