Yes David, some more suggestions:

If possible, boot your system from win to figure out irq and port settings of 
your soundcard. Then enter the win settings into /boot/device.hints config.
from /usr/src/sys/conf/NOTES:

# For non-PnP cards:
device		sbc"isa"

Some DSDTs expext to find a microsoft os on your machine. in case of this the 
tunable "hw.acpi.osname" can be set to the expexted os-name (man 4 acpi).

You can use acpidump(8) to disassemble the ACPI DSDT table to ASL and dump it 
to a file. Edit any suspect code in there and use iasl(8) to recompile ASL to 
AML bytecode. The resulting bytecode can be loaded from userland instead of 
the original AML code by adding the lines  


to your /boot/loader.conf. 

Peter Schultz has written an ACPI howto, which describes step by step how to 
fix your DSDT.
