It sure looks to me like physaddr is getting set to zero in
aggch_init().  It also looks like the device_printf() format string is
missing a newline.

Try adding a device_printf() to aggch_init() to print out both physaddr
and ess->baseaddr so that we can figure out where the calculation
	 ch->offset = physaddr - ess->baseaddr;
is going wrong.  The source file is /usr/src/sys/dev/sound/pci/maestro.c
