If you see "chtrt5645 Analog Stereo" on the input tab, then the UCM profile is not loading correctly. You need to fix that first, if you have an old alsa-lib which did not include a /usr/share/alsa/ucm/chtrt5645 yet, then start with copying both HiFi.conf and chtrt5645.conf from: http://git.alsa-project.org/?p=alsa-lib.git;a=tree;f=src/conf/ucm/chtrt5645 To a directory named: /usr/share/alsa/ucm/chtrt5645 Note you need the plain txt (raw) versions of both files. Then close the gnome sound-settings, do "killall pulseaudio" and re-open gnome-sound-settings. The input should be named "Internal Analog Microphone" now, once you've managed to get the input named that way (so the UCM profile is loaded correctly) try if the buildin mic works now. If things still don't work, then replace the HiFi.conf with the file from the Asus T100HA profile I linked to before *and* put snd_soc_rt5645.quirk=0x0100 on the kernel commandline. Note to test the digital-mic you need both the Asus T100HA HiFi.conf *and* the kernel commandline option. To check the kernel commandline option is present after rebooting do: "cat /proc/cmdline", if you are using the Asus T100HA HiFi.conf, the input should now be named "Internal Microphone" (note no more "Analog" in there).
