 I am experiencing very similar issues on my system as well:
 
 ========================================
 FreeBSD localhost.localdomain 5.0-RELEASE-p7 FreeBSD 5.0-RELEASE-p7 #0:
 Mon Apr  7 05:17:14 EEST 2003
 root at localhost.localdomain:/usr/obj/usr/src/sys/JAGO  i386
 
 pcm0: <Creative CT5880-C> port 0xe400-0xe43f irq 11 at device 14.0 on
 pci0
 ========================================
 
 While sound seems to work most of the time, sometimes, it just seems to
 "vanish" for no (visible) reason whatsoever. When trying to play a sound
 in XMMS, I get the "Couldn't Open Audio" error box that suggests that I
 check that nothing else is blocking sound, my output plugin is
 configured correctly, etc. If I start XMMS from console, the following
 error is printed into the console:
 
 ========================================
 ** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): No
 such file or directory
 ========================================
 
 When I use vchans and force XMMS OSS plugin to use /dev/dsp0.X (where X
 is a number) I get a "Device is busy" error, yet, fstat and lsof show
 nothing that would be using the devices. What's even more bizarre is
 that SOMETIMES, simply clicking the play button again will remedy the
 problem (ie. sound will magically start working), unfortunately most
 often I have to reboot in order to get sound working again. This is also
 not an XMMS-only problem (obviously) as it happens with any sound-using
 app I use (mplayer, games, etc).
 
 Please, let me know if somebody has a proper test case to help isolate
 the problem and if more information is required. I'll be glad to help.
 
 Sincerely,
