Latest working kernel version:2.6.28-3.fc11 Earliest failing kernel version:2.6.29-0.124.rc5.fc11 Distribution:Fedora 11 rawhide Hardware Environment:00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Software Environment:Alsa, Pulseaudio Problem Description: I tested F11 rawhide and with the latest kernel (2.6.29) I have no sound. I post a bug on bugzilla of Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=485295 ) and they respond me it is a kernel bug... I have sound with F11 rawhide and kernel 2.6.28 Tell me if you want any informations... Thank Chepioq
Please show the content of /proc/asound/cards (if any) and the kernel messages.
... and show your kernel config, too.
Created attachment 20294 [details] output of war/log/dmesg
Output of /proc/asound/cards [dominique@localhost ~]$ cat /proc/asound/cards --- no soundcards --- Where I found kernel message and kernel config? I create an attachement for var/log/dmesg
Load snd-hda-intel module with probe_only=1 option. Then give the contents of /proc/asound/card0/codec#* files. I guess it'll work with probe_mask=1 option (without probe_only=1).
[dominique@localhost ~]$ modprobe_only=1 snd-hda-intel bash: snd-hda-intel : commande introuvable and I have not a /proc/asound/card0/ folder, I have just two folder: oss ans seq
For info I attach the content of /proc/asound/card0/codec#* for the 2.6.28 kernel

modprobe snd-hda-intel probe_only=1
Also try to build the kernel sound git tree from git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git This contains the very latest ALSA tree.
Ok "modprobe snd-hda-intel probe_only=1" don't return errors,but no sound and no /proc/asound/card0/ folder and no /proc/asound/card0/codec# files. For comment #10 I don't know how do that....
First unload the module, then load it with the option. modprobe won't complain and do anything when called for a module that is already present.
OK... I do [root@localhost ~]# rmmod snd-hda-intel [root@localhost ~]# modprobe snd-hda-intel probe_only=1 and now I have a /proc/asound/card0/codec# files I create and attachement file: codec1.txt

For info I send you the output for sound of /var/log/messages and /var/log/dmesg

Use probe_mask=0x1 (or probe_mask=0x3 if you need a modem) option as mentioned.
OK... THAT WORK!!!!! I do [root@localhost ~]# rmmod snd-hda-intel [root@localhost ~]# modprobe snd-hda-intel probe_mask=0x1 I have sound, and alsamixer work... But when I reboot I am obliged to do this two lines in console... Thank a lot, Takashi Iwai
> But when I reboot I am obliged to do this two lines in console... See modprobe.conf(5) manpage and "options" line.
Could you give the lspci -nv output? I need to know the PCI SSID. Is it 1179:ff00? Or, at best, once load the driver with probe_only=1 option, then run alsa-info.sh script with --no-upload option, and attach the generated file. The script is found at http://www.alsa-project.org/alsa-info.sh

Thanks. Then it must be the same as Alexy has. The patch below should fix the problem on 2.6.29 kernel.

*** Bug 12810 has been marked as a duplicate of this bug. ***
I reopen this bug: I test actually Fedora12 rawhide, who have a 2.6.31 kernel, and there is same problem: no sound with my toshiba. I do: [root@localhost ~]# rmmod snd-hda-intel [root@localhost ~]# modprobe snd-hda-intel probe_mask=0x1 And I have sound. I think that you have to do a patch for this kernel, like for kernel 2.6.29 (for kernel 2.6.30 they have not this problem...) If you want, I can open a new bug rapport for this. thank. chepioq
Is this still a problem?
The patch that is reported to fix this should be in all mainline kernels as of 2.6.29-rc7. If you still have problems, it is unrelated to this bug, please open a new bug if you can still reproduce the new issue on current mainline kernels.
