@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.
