I really appreciate your working on this. Unfortunately the computer with the problem is owned by a friend in another town. I don't often see him and certainly don't want to upset his stability. If no one else can do this then I would consider driving to him and trying the fix. I was just hoping to have it fixed magically during one of the upcoming updates from Ubuntu.

I've also noted it uses directly a node 0x19 (Audio Output Analog) instead of a node 0x17 (Audio Mixer), but I don't know if it's necessary and has to do with sound quality.

[Bug 886975] Re: Lenovo sound chip Conexant CX20549 Venice doesn't work correctly.
Please read carefully! I've changed the way of providing the sound driver. Now I'm using the DKMS framework so there is no need to wait for my updates. Your system will be always updated with the correct sound driver. I've created a package called 'lenovo-conexant-dkms'. It's a repack of the package provided by Ubuntu Audio Development Team (Brad Figg's link at #36). I'm still using my old ppa (link at #39) so there is no need to change your repositories. Just install the new package called 'lenovo-conexant- dkms'. A description of the changes are in my ppa. I've also included some minor upstream changes. One issue is remaining to resolve. After the updgrade there is still a crackling (popping) sound when rebooting or shutting down the computer although the crackling sound when suspending the computer was eliminated. I'm using the following workaround to also eliminate it: - fire up Terminal and follow the instructions - create a script file amixer-master-mute (or download the attached one) gksudo gedit /etc/init.d/amixer-master-mute - insert the following code to mute the master mixer #!/bin/sh -e ### BEGIN INIT INFO # Provides: amixer-master-mute # Required-Start: # Required-Stop: # Default-Start: # Default-Stop: 0 6 # Short-Description: Mute the Master mixer # Description: Mute the Master mixer to avoid #a crackling (popping) sound #from the speakers when rebooting #or shutting down the computer. ### END INIT INFO case $1 in start) ;; restart|reload|force-reload) echo Error: argument '$1' not supported 2 exit 3 ;; stop) amixer set Master mute /dev/null ;; *) echo Usage: $0 start|stop 2 exit 3 ;; esac exit 0 - save the script and set the execute flag on it sudo chmod 755 /etc/init.d/amixer-master-mute - set to start the script when rebooting or shutting down the computer (arguments are terminated by .) sudo update-rc.d amixer-master-mute start 20 0 6 . - to remove the workaround sudo update-rc.d -f amixer-master-mute remove sudo rm /etc/init.d/amixer-master-mute ** Attachment added: amixer-master-mute https://bugs.launchpad.net/ubuntu/+source/linux/+bug/886975/+attachment/3162181/+files/amixer-master-mute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/886975 Title: Lenovo sound chip Conexant CX20549 Venice doesn't work correctly.

@Brad Figg Thank you. The alsa-hda-dkms package has the same behavior as I previously (#35) wrote about Precise version. Microphone OK, headphones OK, volume slider with unamplified part BAD (there is still sound muted). I've also noted it uses directly a node 0x19 (Audio Output Analog) instead of a node 0x17 (Audio Mixer), but I don't know if it's necessary and has to do with sound quality. I guess that sound going through the node 0x17 is hardware mixed and through the 0x19 is post-mixed by a software driver. As I said I don't know. I'm going to continue with my ppa because the volume slider problem is quite annoying and I believe the node 0x17 is right way of directing sound production. The old model is old but it just works instead of a modern autoconfig script. And I keep that alsa-hda-dkms package installed because it can fill the moment between an official update and update of my ppa version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/886975 Title: Lenovo sound chip Conexant CX20549 Venice doesn't work correctly.

Hi, I also had the same problem. I can confirm that the 3.0.0.14-generic kernel fixes (more or less) the microphone problem. Testing with skype, the sound was a bit crackly. Another thing to notice is that apparently the volume does not scale linearly as would be expected when upping/downing the volume. 4 ticks down from the maximum, the output is to silent too hear (while the slider is at +- 75%). But anyway, it appears things are finally going in the good direction!
