Well, as the MOST of the ASUS boards doesn't work with their shait v6.10.1.6110, v6.10.1.6130 drivers in Windows Vista.. and well only option you have to use is v6.10.1.6100 from asus website which does work..
Here is latest v6.10.2.6200 driver from some company 'ibm' something.. Tested by myself with Vista x86 and x64 system works perfectly and games hell they get nice boost if you had hardware to software audio issues. Although ofcourse not working as hardware audio in this either, but seems fastening things up according to my benchmarks..

[hmm, you still need to do manual install so Extract this with winrar > update straight at Device manager.. It will complain but it will work clean..]
ps. yes I know there is v6.10.1.6300 drivers also sad news is those are not functional by any mean hell I don't even know why they added such up while they have first errors in iniatiazation of the INF..
*updated*
v6.10.1.6220 are perfectly functional tested.. Also the URL apove has the v6.10.1.6300 now and they are also now fixed it seems..
