I did replace the system files "USBAUDIO.SYS" by a "USBAUDIO.SYS" from
XP (my account is an Administrator one, the filesize of Vista's
"USBAUDIO.SYS" is 70Kb and the XP one is ~58Kb).

On my Vista, the USBAUDIO file is located in 2 locations:

-c:\Windows\System32\Drivers
-c:\Windows\System32\DriverStore\FileRepository\wdm a_usb.inf_9ce240de

right click on the file and click on properties,

tab security-> click advanced,
tab owner-> then click edit
select administtors and press ok -> you will get a message telling you
that you are about to change the ownership click ok and then click ok
till you get back to the frist menu.

then you have to change the permissons on the file

click advanced
in the permissons tab highlight the admin
the click edit,

double click on admin again
select the allow full control box--- then click ok untill you get back
to the front screen....

you can now replace the file without any trouble.
Then I copied the c:\windows\system32\usbaudio.sys to a "usbaudio -
VistaBackup.sys". I put the XP one as the "usbaudio.sys". Everything
worked.

Thanks to Ramey and David for the info.

Good luck
