Nov 13 update breaks Media Player's ability to recognize Firewire audio device

I use an Echo AudioFire8 external audio interface that communicates with the
computer via a Firewire (IEEE1394) port. All worked fine until this morning
when Windows Media Player suddenly ceased to see the device, saying "sound
device not installed or driver missing." Windows control panel sees it just
fine as does Winamp, VLZ media player, and Real Player. Only Windows Media
Player (and the Internet Explorer player component) fail to see it's there.
The only thing that has changed in the system is the installation last night
of the Nov 13th update patch package. Have removed and resinstalled the
Audiofire drivers to no avail. Win XP, SP2 with all updates applied is the
OS. Anyone experienced a similar problem? Any ideas?

No, since I don't have an external audio device here ;)

In case you want to make sure that KB943460 (MS07-061) is causing the
quirks on your machine, have a look into the "More Information" section
in http://support.microsoft.com/kb/943460/en-us and use the registry
hack to *temporarily* disable the "advanced" URI checking coming with
KB943460. In case you've installed IE7 on your system, it's IMHO more
than *essential* to apply KB943460 and to *not* use the registry hacks.

Is this update known to affect I/O with firewire 1394 port devices?? Since
I'm,playing local mp3 and avi files, I'm trying to understand how a bad url
vulnerability should influence it.

Not yet, not to my knowledge. It "may" be the URI issue fixed with the
update.

Have you tried the registry "hack" mentioned in
http://support.microsoft.com/kb/943460/en-us already?

Nope, but this evening I discovered that somehow the updates m ust have
affected the directsound drivers. Switching the "speakers" selection in the
MediaPlayer options to "default direct sound" rather than a specific I/O
channel restored normal function. It's as if the settings in Media Player
and the settings in the windows control panel were being interpretted as
being two separate programs competing for the same device! Very weird.

Hm, strange. Which version of WMP are you using? I'm not seeing a change here.

i am only a one day old vista user, so this is probably a stupid ?, but ...
when i go to the media player options devices speakers advanced i only get
the one installed speaker choice, and not this default setting. i have a
rowland dr880 drum machine i want to play midi files over from the player,
but it only recognizes the speakers. if i go to the control panel device
manager audio there they both are, speaker and my dr-880, but the player
doesnt seem to recognize its there?? maybe the problem is in this default
setting or getting the media player to scan for other output devices?? HELP

Barn
What makes you suspect that WUs has got to do with your sound problem?
For that matter which update do you suspect?
Any error codes/ event viewer entries etc?
What Vista? - is it upgrade or brand new computer?
What Media Player? WMP?
Have you looked in Device Manager or whatever its called in Vista to see if
drivers for the sound are working.?

yea this problem probably doesnt fit in here in WU, but it was my first time
in this forum, and i saw the previous postings about setting the WMP (mine is
11 for Vista) for different output devices, and thought you guys might know
about this. its a brand new computer (dropped my old laptop!) and like i
said above i do see my dr880 driver in the device manager audio, and in fact
it works for some of my other midi software (Allegro) just fine. i just want
to play midi files to the drum machine, not thru the speakers.

Well at least you Xposted to the Media group - lets hope it gets dealt with
in there as you have had no help here from updates.
Good luck
