Ubuntu for ac100 uses ucm config (placed in /usr/share/alsa/ucm/) for audio device (thanks to ogra!). So I suppose we just need to add few lines to the config to enable internal mic (dmic): cset "name='DMIC En Capture Switch' on" cset "name='DMIC PreFilter Capture Switch' on" cset "name='DMICL Mix DMICL2ADC Capture Switch' on" cset "name='I2SOut Mux' 'ADC LR'" cset "name='DMIC Boost Volume' 100,100" cset "name='Rec Capture Volume' 100,100" I'm not sure about Volume values (I don't have my ac100 with me and can't check what values are good - very high values can produse noise).

My history is described here -- https://answers.launchpad.net/ac100/+question/207758 : before turned on a lot of switches in alsamixer, no sound could be recorded. I couldn't turn capturing the sound on through the sound settings menu in the panel. I suggest that either the default settings allow recording, or there is a simple way to switch it on through the settings menu (without having to look at a whole lot of switches in alsamixer, not understanding their meaning).
