I agree. It looks like it should work.

sorry not to have more info to help,

After reading the man page for snd_hda and dev/snd/pcm/dsp.c src I don't think
you *need* hints in /boot/loader.conf to make it work, but you can re-arrange
'pins' and set auto stuff, like plugging headphones in selects the device. i
think.

here's some stuff to check. I am *guessing* it's 'recording' from a different
pin/device??

on this machine :

[1070] > syscntl hw.snd.default_unit 
hw.snd.default_unit: 3

[1071] > dmesg | grep pcm3
pcm3: <Realtek ALC887 (Rear Analog)> at nid 20 and 24,26 on hdaa1

[1072] > sysctl -a | grep nid20
dev.hdaa.1.nid20: pin: Line-out (Green Jack)
dev.hdaa.1.nid20_config: 0x01014410 as=1 seq=0 device=Line-out conn=Jack
ctype=1/8 loc=Rear color=Green misc=4
dev.hdaa.1.nid20_original: 0x01014410 as=1 seq=0 device=Line-out conn=Jack
ctype=1/8 loc=Rear color=Green misc=4

[1073] > sysctl -a | grep nid24
dev.hdaa.1.nid24: pin: Mic (Pink Jack)
dev.hdaa.1.nid24_config: 0x01a19c40 as=4 seq=0 device=Mic conn=Jack ctype=1/8
loc=Rear color=Pink misc=12
dev.hdaa.1.nid24_original: 0x01a19c40 as=4 seq=0 device=Mic conn=Jack
ctype=1/8 loc=Rear color=Pink misc=12

I think there's probably a pink jack on the back of the machine where i can
plug up a mic.

 a thought, did you already experiment to see if you can record something from
oss /dev/dsp devices?
I browsed through the source but I don't understand, at the moment, how to
'know' which /dev/dsp maps to pcm.
