Subject: High pitched noise with snd_hda_intel since linux-3.9.0

Hi,

since linux-3.9.0 (and until the very last stable 3.10.1) I can not use
sound on my lenovo thinkstation s20. On early system boot (I guess when
snd_hda_intel module gets loaded) I have a very annoying high pitched
noise and I have to turn off my speakers (I recorded a small video with
my phone:
https://dl.dropboxusercontent.com/u/2909401/fpirisp.snd_hda_intel.mp4 ).

As sound is not critical at all on this box, I had’nt bothered trying to
figure out what was the cause until recently.

I have googled quite a bit and haven’t been able to figure at all if
it’s a bug in the kernel or a configuration problem on my side.

So, as sound was working ok on 3.8.9 and it began failing on 3.9.0; git
bisect tells me that the first bad comit is this one:

|     ALSA: hda - Merge Realtek parser code to generic parser
| 
|     Finally the whole generic parser code in Realtek driver is moved into
|     hda_generic.c so that it can be used for generic codec driver.
|     The old dumb generic driver is replaced.  Yay.
| 
|     The future plan is to adapt this generic parser for other codecs,
|     i.e. the codec driver calls the exported functions in generic driver
|     but adds some codec-specific fixes and setups.
| 
|     As of this commit, the complete driver code is still duplicated in
|     Realtek codec driver.  The big code reduction will come from now on.

Could anyone, please help me figure out what is the problem?

Following is some information about my system. Please, let me know if I
need to provide any additional information.

This is the output of lspci of my audio card(s):

And I’m attaching my kernel config.

Thank you in advance.
