Comment 49 for bug 440251

I tried the suggestion by David Henningsson (#48) and it didn't make any difference. I followed the instructions and the package installed without problems,

After reboot, the mic still doesn't work, and the weird interaction between console alsamixer and the pulseaudio applet persists: when using alsamixer on the command line to switch to 'internal' or 'mixed' inputs, it switches, but does not cause the audio to work. Then, going to the applet shows the mic as 'mute'. Unmuting the mic in the applet causes the input source in the alsamixer to revert to 'external'.

On a side note: I have several colleagues with X301's and for them it seems to work out of the box. Maybe (slightly) different hardware.
