You have to post output of alsa-info.sh after you turn on analog

It is not clear how you adjust the playback volume of line in / mic
If it is mix of dac and adc for karaoke, it also need adc recording

IDT/Sigmatel codecs --- * Analog Loopback This control
enables/disables the analog-loopback circuit. This appears only when
"loopback" is set to true in a codec hint (see HD-Audio.txt). Note that
on some codecs the analog-loopback and the normal PCM playback are
exclusive, i.e.
You have to turn on analog loopback using amixer or alsamixer
