 Can you please clarify why a sysctl handler is required?  
 
 My understanding of the code is that dsp_oss_audioinfo() does not store the 
 device capabilities but gets called every time dsp_ioctl() is called with 
 SNDCTL_ENGINEINFO thus there is no persistent state to update when 
 hw.snd.default_unit changes?
