I can't ssh to the laptop at this moment, but if the sound card is not 
detected by the kernel, can I force the detection by editing /boot/
loader.conf with:

userconfig_script_load="YES"
snd_maestro3_load="YES"
?

I have that in loader.conf on an identical laptop running 4.9-STABLE, and on 
that laptop:

I suppose on the 5.2-BETA laptop I should see something similar?

Thanks,
