Bug Description

I've installed Ubuntu 12.04 for Toshiba AC100.
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).

 I don't think that it is a bug.

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).

Re: it's not a bug

I think that it's a kind of a bug of the distro that the microphone (neither external nor internal) can't be turned on in the "standard" settings menu exposed to the users.

So, perhaps, such a simple setting should be there in the sound settings menu, or the microphines should just be enabled by default, as danindrey@ suggests above.
