``` `alsactl monitor` (Unplugging and plugging the mic) ``` node hw:2, #12 (0,0,0,Line - Input Jack,0) VALUE node hw:2, #12 (0,0,0,Line - Input Jack,0) VALUE ```
`amixer -c events` (Unplugging and plugging mic)
``` event value: numid=12,iface=CARD,name='Line - Input Jack' event value: numid=12,iface=CARD,name='Line - Input Jack'
``` It appears the Mic In is being incorrectly identified as the Line In and I cannot record any sound through this jack.
