Hi, got a Gigabyte X58A-UD5 Rev 2.0 m/b with audio problems when Flashplayer 10 installed. The sound stutters,warbled, etc. However, when I uninstalled the Flash player 10. It appears that the problem is gone. O/S is Win XP Pro SP3 and all the latest updates installed.
Go to the realtek site and download/install the latest HD audio driver, then install the latest adobe flash from the adobe site.
first thing I did was update to the latest driver. No luck. Reinstalled everything, same problems. Sent the m/b back for an exchange since Gigabyte has no solution for these audio problems. Thanks for your help.
