Comment 13 for bug 874880

I went through that fix again (https://help.ubuntu.com/community/HdaIntelSoundHowto). I failed the first time, but my second try worked. I am working on a R61e Lenovo Thinkpad. The result of "cat /proc/asound/card0/codec* | grep Codec" was "Codec: Conexant CX20549 (Venice)" on my machine. The chipset is a Conexant 5045 (verified with a Google search of the Codec response above). The model that worked for me was "laptop-micsense". It is possible that "laptop-hpmicsense" would have been a better fit, but the first one worked for fixing the headphone issue and I have not discovered any other problems. (I just guessed, as none of the models listed under that chipset really looked like a good fit.)

I hope that someone will use this information to fix the root of this problem. I ended up spending several hours of research and testing to fix this on my computer, and I suspect that most people would just give up and leave with a bad feeling about Ubuntu.
