How can I use a Mic on Linux based Tardis Workstations?
Connect your Microphone and Headphone to the front panel of your Tardis Workstation. (the default settings are for the front panel, but you can make your own settings supporting the rear panel) and load the mixer state file.
alsactl -f mixerfile restore 0`
Or you could use alsamixer or kmixer to configure the sound mixer manually
For recording use rec, a simple command line recording tool or audacity a gui recording tool.
