Description of problem:
Laptop speakers does not work on ThinkPad x201. When I add
options snd-hda-intel model=thinkpad
to /etc/modprobe.d/sound.conf sound works but only for a few minutes. After few minutes integrated speakers remain silen until next reboot or until
rmmod snd-hda-intel && modprobe snd-hda-intel
when I use
options snd-hda-intel model=thinkpad power_save=0 enable_msi=0
it works longer but usualy less than one hour. Sound output from headphones jack works correctly all the time. I did not found anything in dmesg or /var/log/messages.

Are you still seeing this with the 3.9.4 kernel in updates-testing?

Still the same problem.
I noticed I have stray pulse-XXX directories in /tmp that are empty.

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

still present in f18, but I cannot find how to change the Version above.
--- Additional comment from Martin Bengtsson on 2013-07-30 05:22:04 EDT ---
Also present in fedora 19.

I also have this problem, in RHEL Workstation 6.4

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs.
Fedora 19 has now been rebased to 3.12.6-200.fc19. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 20, and are still experiencing this issue, please change the version to Fedora 20.
If you experience different issues, please open a new bug report for those.
This was confirmed as an hardware issue finally.
I went to Lenovo service with complain that there is no sound from speakers
1) They replaced speakers module, which did not help.
2) They replaced motherboard which also did not bring any improvement.
3) There is small PCB on the right side of the computer. This PCB is called IO board. After replacing it, sound works as expected.
If you run into this issue, please ask your service company to replace this board.
Closing this issue. It is not software problem.
