It seems like the issue can be solved by removing pulseaudio.

Please look at the diff below. I won't have much time till Tuesday. Will
read how to try to use early patching then. Thanks.
I've also send bug report to the alsa-de...@alsa-project.org. It waits
approval from moderators. Will post the link to email as soon as it will
be approved.

Sorry, just realized the message was too long. Attached diff between
alsa info for working and broken kernels as file.

I'm still doing bisection. Taking a lot of time. Meanwhile I've
collected some logs from good kernel:

use hdajackretask or early patching to fix the pin default if spdif node

this is the patch which drop static model and use auto probe
you have to fixup missing pin and any regression of this patch

You received this bug
case AD1984_THINKPAD:
- if (codec-subsystem_id == 0x17aa20fb) {
- /* Thinpad X300 does not have the ability to do SPDIF,
- or attach to docking station to use SPDIF */
- spec-multiout.dig_out_nid = 0;

Thank you Raymond, I will look into patching it. I have no experience
working with kernel or audio driver. Will need to read the code and
documentation. It may take some time. But I could quickly confirm what
5ccc618fee67f0f0b2122dd4b32a02fd2b6a1569 is the commit, which causing
the problem.

Alexander Fedora, the issue you are reporting is an upstream one. Could
you please report this problem through the appropriate channel by
following the instructions _verbatim_ at
https://wiki.ubuntu.com/Bugs/Upstream/kernel ?
Please provide a direct URL to your e-mail to the mailing list once you
the easy way is
diff -u workingalsainfo nonworkingalsainfo
you can use early patching to disable independent headphone by hint and
fixup spdif pin
since stereo mix is disalbed as it conflict with auto Mic selection

Alexander Fedora, the next step is to fully commit bisect the kernel in
order to identify the offending commit. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Confirmed bug exists in the latest upstream kernel:
Linux x61s 3.15.0-031500rc7-generic #201405251935 SMP Sun May 25
23:36:23 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
No, I didn't saw this bug in previous versions of ubuntu.
I've also stumbled upon very similar issue on askubuntu site:
Alexander Fedora, as per http://download.lenovo.com/express/ddfm.html an update
to your BIOS is available (2.22). If you update to this following
https://help.ubuntu.com/community/BiosUpdate does it change anything? If it
doesn't, could you please both specify what happened, and provide the
I've updated bios. It didn't solve the problem. Speaker still not
working properly.
sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date
7NETC2WW (2.22 )
03/22/2011
** Changed in: linux (Ubuntu)
Status: Incomplete = Confirmed
** Tags removed: bios-outdated-2.22
