Hi, I'm contemplating upgrading my 2.0 setup to 5.1, I'm just debating with myself if it's worth it - but I have a logistical query with regards to which output would be best. I don't want either of my displays going through an AV receiver for various reasons, so the AV receiver will be doing audio only via Optical/Coax or via HDMI? In theory I think I should be able to have a HDMI cable from my gfx card to the AVR and telling windows to only send audio via that. However this seems like it could be a bit of a mess with windows potentially picking up the AVR as an additional display? Which leaves me with digital out from my soundcard. But unless I'm mistaken, I'd lose out on DTS-HD etc? Thoughts? Has anyone a similar setup?
