ASUS Xonar drivers - Norton removed cmudaxp64.sys during installation.

I just downloaded Win10 drivers for my soundcard (ASUS Xonar STX).  During the install Norton deleted one of the files (cmudaxp64.sys) as unsafe.  I can't get any more information about the file from the Norton app.

The top page of google hits about this file is all "fix your windows computer" sites, many of which have been flagged by Norton as unsafe.

I'm not sure how essential this file is for my driver.  It came from the ASUS drivers download site.  How should I investigate further about whether ASUS is distribuing malware in their drivers or find out if this could be a false positive that Norton is flagging?  Is there a way to find out from Norton more details about why the file is getting cleansed?
