Public bug reported: Sound and webcam works perfectly. I cannot use the microphones of my Laptop, however the line-in is working. This means when I play music on my laptop and use line-in, I can record it. Using the microphone, sound- recorder does even not start recording.
Everything is unmuted. It works fine with the Ubuntu Live CD. As soon as I install Ubuntu I encounter this issue. In order to fix the issue I had to add the below line into /etc/modprobe.d/alsa-base.conf options snd-hda-intel position_fix=1 Mic volume works correctly under sound recorder now ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: alsa-base 1.0.23+dfsg-1ubuntu4 Uname: Linux 2.6.36-999-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
