maestro3 sound problem on Dell Inspiron 4000

[Jason W. Barnes]

	I have been unable to get sound to work on my Dell Inspiron 4000
under FreeBSD 5.3.  Until last Tuesday I was running 4-STABLE, under which
sound would work, but only after I had put the computer to sleep (zzz),
and then brought it back up.  Before that, any attempt to play sound
resulted in an application that thought it was playing sound, but no
actual audio emanations from the laptop.
	Under 5.3, I have the snd_maestro3_load="YES" in my loader.conf,
and a kldstat confirms that maestro3 and its attendant modules are indeed
loaded and seem to be functioning.  Here's an output of /dev/sndstat:

FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <ESS Technology Maestro3> at io 0xd800 irq 5 kld snd_maestro3 (4p/1r/0v channels duplex default)

	I have tried the same sleep trick that worked in 4-STABLE to
recover sound usage, but it does not work in this case, even though the
computer's sleep and recovery therefrom seem normal.  When the computer
first boots, it emits a loud beep, implying that the sound *is* working at
initial bootup, but must be messed up later in the boot process.
	I have become quite exasperated with this problem.  I was
wondering if any of you out there in mailing-list-land might have
encountered a similar problem, or have any ideas as to what I might try to
fix my issue.  For reference I have included a copy of dmesg below my
signature.
	Thanks in advance for any help you might have,
