I think you probably just need to set hw.snd.default_unit. e.g. I have: 

$ dmesg |grep pcm
pcm0: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 1 nid 1 on hdac0
pcm2: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 2 nid 1 on hdac0
pcm3: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 3 nid 1 on hdac0
pcm4: <HDA VIA VT1708S_0 PCM #0 Analog> at cad 0 nid 1 on hdac1
pcm5: <HDA VIA VT1708S_0 PCM #1 Digital> at cad 0 nid 1 on hdac1
pcm6: <HDA VIA VT1708S_0 PCM #2 Digital> at cad 0 nid 1 on hdac1

and in /etc/sysctl.conf I have 

hw.snd.default_unit=4

to select the analogue output from the motherboard rather than (I
presume) the HDMI output from the graphics card.
