by default the DACs on the Revo 5.1 are set to maximum volume, you can find the datasheet of AK4358 here: http://envy24.svobodno.com/ so if a driver can provide more loud sound with Revo 5.1 then it do volume processing in software, so i'm awaiting to test and report the results from the latest version version with software volume. P.S. i also will send you another 2 test versions, that will route sound to the different output and that don't write to AK4358 volume registers at all, so AK4358 will use the default volume values, which means maximum volume.
