Query on Win-7 USB Audio driver.....

Hi All,

I saw an article on “modifying the USB Audio driver (usbaudio.sys) buffer” at below link.
http://support.microsoft.com/kb/953228. This article was for Windows Server 2008 & Win-VISTA.

How can we modify the USB Audio driver buffer size in Windows-7?
I tried the same approach described in above article on Win-7 by adding regkey “CapturePacketsPerUrb”.
But it didn’t work. I did not notice any difference in the requests issued by “Usbaudio.sys”.

Is there a way to adjust audio duration on Win-7?
