First, have a look here: Handbook: 7.2. Setting Up the Sound Card

The easiest is to load snd_driver; kldload snd_driver, this is not a specific soundcard driver but it'll load all available soundcard drivers. Then have a look at what's actually being detect by running cat /dev/sndstat.

ALC887 is an snd_hda(4) codec and is statically compiled in the kernel for FreeBSD => 10.* .
There is no need to kldload snd_driver. Section 7.2 of the handbook was written for FreeBSD =< 9.* and should be updated.

FreeBSD groups sound inputs/outputs by location. PCM1 may be a grouping of the rear panel jacks while the PCM2 grouping may consist of the front panel headers. PCM0 could be the HDMI output on your video card. By default, FreeBSD only uses one grouping.

This is a usb audio device. Are you also using a usb device in addition to the built-in audio devices on the mother board? Which one would you like to use as the default?

The built-in audio devices can be determined by
# sysctl dev.hdac.1.pindump=1 && dmesg

uadio isn't HDA. uaudio used here for a usb web cam with microphone as usb sound device.

dmesg says:
Code:
hdac0: <Intel Panther Point HDA Controller> mem 0xf7e10000-0xf7e13fff irq 22 at device 27.0 on pci0
hdac0: Unable to put hdac in reset
----
hdac0: Command timeout on address 2
hdac0: Command timeout on address 2
hdac0: CODEC is not responding!
sound is works on this motherboard in other OS
