All the above info has been posted from the Fedora 8 test 2 live cd. I will post more info (the above files before model=auto and also amixer output from arch linux where this feature works). Please bear with me :) Thanks ! Created attachment 196361 [details]

Ahh, now I think I have provided maximum possible information required for this bug :) For the record, I'm using Arch Linux -current, not some frozen stable branch. Arch uses kernel 2.6.22.6 .. The patches applied to Arch's kernel can be found here - http://cvs.archlinux.org/cgi-bin/viewcvs.cgi/kernels/kernel26/?cvsroot=Current&only_with_tag=CURRENT If some more information is needed, please tell me. I think this bug has been fixed upstream, but is pending a sync in the fedora repo.. Thanks once again ! Ok the URL to arch repo has changed, it's now - http://cvs.archlinux.org/cgi-bin/viewcvs.cgi/base/kernel26/?cvsroot=Core&only_with_tag=CURRENT OK after some more diagnosis it seems that it works on Arch Linux because it uses ALSA patches which are newer than either kernel 2.6.22 or 2.6.23-rcX. The newer patches which arch applies to kernel 2.6.22 (which fixes this bug) are - http://www.archlinux.org/~tpowa/alsa-patches/alsa-20070818.patch.bz2 http://www.archlinux.org/~tpowa/alsa-patches/alsa-include-20070818.patch.bz2 I am attaching those two patches individually here too, for convenience.

Ok, doing some digging upstream, I'm positively sure that this commit in alsa repo fixes the bug. Though I've yet to try it myself, there is no other commit upto now which seems to have fixed the bug. Commit - http://hg.alsa-project.org/alsa-kernel/rev/2c9a8e76669e The complete revision history of patch_realtek.c can be seen at http://hg.alsa-project.org/alsa-kernel/log/3a300e020eca/pci/hda/patch_realtek.c Ok, this has GOT to be the patch that fixes it - http://hg.alsa-project.org/alsa-kernel/rev/c9f96ebed522 and it's dependency seems to be http://hg.alsa-project.org/alsa-kernel/rev/2c9a8e76669e I'll try and build a kernel which incorporates the patches, and report back :-) OMG THAT FIXES IT ! Applying the above 2 patches to kernel 2.6.23-rc7-git5 fixes the bug without anything else required ! No other dependencies. Can we please have the bug fixed in fedora rawhide for fedora 8 release now ? Thanks :-) Which patches were applied? c9f96ebed522 from comment #16 does not apply, with or without the other patch from that comment applied. The 2c9a8e76669e modifies some non-existent documentation file. Just removing that much part from the head of the patch allows the patch to apply cleanly. The c9f96ebed522 has some rejects, but when merged in manually by me, the patch applied cleanly. The problem occurs because of other patches in between these 2 and the upstream kernel version of the same file :( As Fedora 8 uses alsa 1.0.15, the bug is resolved ! Thank you very much !! I've a HP Pavilion DV6605us and Fedora 8 installed in it. I'm getting sound from both Speakers and Headphone. Does the above mentioned patch will work for HP laptop too? If so, please tell me how to apply this patch? The above mentioned patch was taken from the development tree. It is no longer relevant, as that patch has already been merged upstream. For your laptop, you should check the ALSA database for the corresponding sound card - http://alsa-project.org/main/index.php/Matrix:Main HTH. |
