Razor AC-1 passthrough possible?

I finally got my AC-1 from Woot after 3 weeks. I am trying to get it to passthrough the spdif and I cant figure out how to do it.

I downloaded the newest drivers from the Razor website. The only spdif out options are Dolby Digital Live, DTS, and 2 channel(44.1, 48, etc)

If I choose DD Live even when I play DTS movies my receiver only receives a DD signal and when I choose DTS and play a DD movie my receiver only receives a DTS signal. It wont switch over with different formats

I have my receiver on "auto" so it decodes whatever signal is sent to it and I want to pass the bitstream from the card to my receiver and have my receiver decode the format, but I can't figure out how to do it.

Someone else with this card, please tell me this is possible

I also just noticed no matter what it only outputs to my front two speakers, no center and no surround

Ok, I got the card to output to all speakers, it was a softwar(ffdshow) problem

It seems you cant do a simple passthrough with this card. You need to switch formats manually which is a real pain. I prefer DTS and the DD movies seem to play fine in that format so I will just leave it on DTS

Not ideal, but it works and it sounds really good

AC3 Filter...this will solve the problems you are describing. Use it

the problem is with the AC-1 software, it simply does not have a passthrough option

there is...

DD live
DTS interactive
Digital Audio 24-192k
spdif in loopback
spdif off

those are the only options

i have CCCP installed and i think that includes the most recent AC3filter?

if we can fix this that would be great
