I found bug when try using snd_hda module on FS Lifebook P7120
snd_hda does not properly enumerating input lines
'line' in reality is 'mic' and not muted on startup. in mixer line has level 75 and after loading driver i have very loud sound from speakers (because audio loop between spkrs and mic).   

>How-To-Repeat:
simply enable snd_hda in /boot/loader.conf
and reboot
>Fix:
do not load snd_hda from loader.conf
load it from cli
kldload snd_hda && mixer line 0
