I have a
Lenovo x230 running
Ubuntu 12.04.3 (and previously 12.04.2).
I had been trying to use
audacity to record audio from a stream on a website and ever since the internal mic has been problematic.
For the most part the microphone does not register any input on the internal devices tab of
pavucontrol and if I try to use something like
skype the other end just hears static.
I have had some success getting mic input working by changing settings in
alsamixer but again there does not seem to be anything reproducible to make this happen and it is not permanent, typically putting the computer to sleep or rebooting and I am back to square one.
Would anyone have any suggestions on how to reset the microphone or reconfigure it to consistently work or even ideas for further troubleshooting?
