Conexant CX20549 Patch for ThinkPad R61i?

[J.P.]

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.

Hi J.P.,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 476174

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

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.

Unfortunately as this machine is my primary workhorse I don't think I will be able to test the mainline kernel at this time. What I can tell you, however, is by applying the Conexant patch in the original report and rolling it into ALSA from source, the issues are resolved (i.e., working microphone, reasonable sound levels). Currently in Karmic with the compiled and installed ALSA + patch I do not have the issues until a kernel update which breaks it and the problems return (then I have to repeat the installation process using the ALSA script as described in the forum thread).

I am currently testing Natty Alpha 1 and this issue still persists. The fix is to compile ALSA from source with the patch as described in the original submission.
