Sound card issue

I have recently installed FreeBSD 5.1 on a Compaq with onboard sound. 
WinXP identifies the
card as an "ESS Allegro PCI". Compiling the kernel with the "pcm" option 
did not load the
driver or show up in the "dmesg" output. I chose the load all sound 
drivers in the
/boot/loader.conf file. It loaded the "maestro3" driver. This is the 
output of my "dmesg"

CHRIS >}> dmesg | grep snd
Preloaded elf module "/boot/kernel/snd_maestro3.ko" at 0xc04470cc.
CHRIS >}> dmesg | grep pcm
pcm0: <ESS Technology Allegro-1> port 0x1000-0x10ff irq 5 at device 5.0 on 
pcm0: failed to enable memory mapping!
pcm0: <ESS Technology ES1988 AC97 Codec>

The problem I am having is that after about 30 seconds, the sound card 
hangs on one note
and the only way to stop it is to load another sound application. If 
anyone has had this
problem before, Please Help. Thank you for your time in this matter.
