I don't have the id info on the exact updates at hand right at the moment.
There was a package of three updates downloaded through the Windows
autoupdate facility when I started the computer the evening of the 13th and
it was after that download installed that the problem surfaced. This
"soundcard" is a 10 channel (8 analog, 2 digital) professional audio
workstation interface, an external box communicating through firewire. The
WDM drivers are set to use analog channels 7/8 for normal stereo playback
under the audio device settings for both sound and voice in the control
panel. I don't know the settings in WMP itself before the update, but after
it installed the WMP hardware options settings for the speakers showed set
to "DirectSound:AudioFire 7/8." When attemping to play anything - mp3, wav,
avi, mpg, wmv, wma - it reported "device not installed or in use by anthoer
program". I finally tried changing the WMP speaker setting to
"DirectSound

efault" and that fixed it.
