"The snd_hda(4) driver has been updated. This changes include support  
for multiple codec per HDA bus, multiple functional groups per codec,  
multiple audio devices per functional group, digital (SPDIF/HDMI)  
audio input/output, suspend/resume, and part of multichannel audio.

Note that due to added HDMI audio and logical audio devices support,  
the updated driver often provides several PCM devices. This means that  
in some cases the system default audio device no longer corresponds to  
the users's habitual audio connectors. In such cases the default  
device can be specified in audio applications' setup or defined  
globally via hw.snd.default_unit sysctl, as described in the sound(4)  
manual page."
