I have problems with my sound. With voodooHDA it work but it is at very low volume, I can hear something when I MAX my creative. I tried to delete voodoohda and install multishit, but with it my sound doesn't work at all. I requested help in forum, and forum develoaper said that you can help my and do something with DSDT.
my mb is: GA-790xta-ud4, amd phenom 2 x4 955, ALC889, Ati radeon 5850 1gb.
he said: "You can ask for a DSDT to the developer here (tell to him if is possible he add HDEF to the yours)"
