[Bug 476174] Re: Conexant CX20549 Patch for ThinkPad R61i?

[J.P.]

Hi, I'm testing with the Lucid RC and the problems still persist.  The
PCM is turned all the way up and the sound is distorted; this has been
the case going back to Gutsy since I've had this machine.  I tried to
record something with Sound Recorder and I expected to hear my own voice
when playing it back.  There was nothing heard.

As requested, I'm sending the attachment.

** Description changed:

  Feel free to mark this as a dupe of 278648, but as of Karmic, ThinkPad
  R61s with Conexant CX20549 (Venice) sound devices have non-functioning
  microphones and less-than-stellar sound output.  This submission is in
  hopes that ALSA can be patched by the Lucid LTS to include a working mic
  and fully functional sound.
  
  Currently the workaround requires the following:
  
  1.  Grabbing the ALSA upgrade script from
  http://ubuntuforums.org/showthread.php?p=6589810
  
  2.  Downloading the Conexant patch from
  https://bugtrack.alsa-project.org/alsa-bug/login.php?username=guest&password=guest&return=/alsa-bug/view.php%3Fid%3D4163
  
  3.  Applying the patch:
  $ cd /to/your/directory/where/the/script/is/saved
  $ sudo sh ./AlsaUpgrade-1.0.x-rev-1.17.sh -d
  $ sudo patch /usr/src/Alsa-1.0.20/alsa-driver-1.0.20/alsa-kernel/pci/hda/patch_conexant.c ~/path/to/patch_conexant.c.patch
  $ sudo ./AlsaUpgrade-1.0.x-rev-1.17.sh -i
  
  4.  Saving the patch and script in case of future kernel upgrades (at
  minimum performing the last command in step 3 after a kernel upgrade).
  
  5.  Upon rebooting, readjusting sound levels and performing the general
  PA fixes as suggested by other Ubuntu forum threads.
  
- According to the comments in 278648, this has NOT been submitted
- upstream and there doesn't seem to be a consensus on how to best notify
- upstream of the patch.  This is a potential showstopper for those with
- R61i machines who need to be able to use the microphone and the sooner
- this patch can be applied before Lucid, the better.
