I a using a hercules fortissimo card and have configured it for digital output through the hercules control panel However, while it is passing DD and DTS soundtracks to my amp just fine (over a digital optical cable) I cannot get it to upsample any non DVD player sourced sounds and play them. i.e. no windows sounds at all. Does anyone know if this is possible with this card. I also have a Philips Sonic Edge 6.1 card sitting here but as that uses SPDIF not digital optical I would prefer to stick with the fortissimo if possible. If none of these will work can anyone suggest a good reasonably price sound card that will deliver windows based sounds and DD/DTS soundtracks from a DVDM to my amp. I have considered the M-Audio Revolution but don't want to spend yet more money if what I have should/will work. Thanks.
