ah i found the solution to 100% working card:
go to
http://www.realtek.com.tw/downloads/dow ... Down=falseand download the
High Definition Audio Codecs, i did not try the ac'97 codecs, bit it just might work aswell, since in vista i had those installed by default.
just make sure you download latest version, with support to win 7, those on install DVD
do not support win 7.
this file solved my problems:
OS: Vista, Windows7 Driver (32/64 bits) Driver only (ZIP file)
version: R2.45 2010/3/22
size: 56079k
all the rest drivers are properly located on diver & utilities DVD, just make sure you install all of them, even if some of the hardware works properly (example, graphics was ok, however, in hardware manager it was only as "standard VGA controller, so that had to be reinstalled with nvidia's drivers)
if you have problems with second hard drive like me (one disk wasn't recognized), go to control panel, administrative tools and find disk management, probably second drive has no drive letter assigned (example E: ), simply attach the letter, and voila, you just got one working drive with partitions back again, and no data lost

this solved all issues with my xa2528 and win 7 Pro, works better like with vista
