Marc is correct that my previous post makes little sense and section and section 7.2.1.1 is good as it is. I was trying to recall what I did a couple of days ago and by mistake I focused on 7.2.1.1 when my suggestion really applies to 7.2.1. (That's why I was mixing up loader.conf and kernel config file syntax.) Section 7.2.1 explains how to use # kldload snd_emu10k1 on the command line or put=20 snd_emu10k1_load=3D"YES" in /boot/loader.conf. I think this needs to be # kldload sound # kldload snd_emu10k1 and=20 sound_load=3D"YES" snd_emu10k1_load=3D"YES" However - I'm not 100% sure this is correct - so this should only be added if someone else knows that this is an obvious omission. I'll carefully verify this if needed, but will not be able to get back to the machine for two weeks. What I do know for sure is that snd_sbc_load=3D"YES" did not work for me (sbc0 card found, but /dev/sndstat listed no installed devices), but snd_driver_load=3D"YES" worked (snd0 shows up in dmesg and audio works great). While 7.2.1.1 seems complete I think 7.2.1 implies that only the driver for the specific card is needed and does not mention the generic audio driver.
