yeah I'm also very pissed with mine from 5.1 to 2.1 not exactly 2.1. vista still says 5.1 but it's either centre sound will go the right side or rear would completely disappear or front left/right would go to centre. had to reboot just to temp fix the sound. but after installing danielK's support pack 2.0 it seems that it has gone away.. still need a few more days to confirm that.
connection to speakers are analog. I tried optical. same problems. optical as in "encoder DTS connect" rather than set SPDIF as default.
but i did realized that I had that problem when I am using CMSS. when i disabled everything. it doesnt occur cuz the rear and centre isnt used for music.
the channel shift is during music and video.
This is actually a problem with Vista itself, not the drivers. daniel_k's driver packs only fix this issue about 50% of the time, but I have seen some instances where other problems have cropped up . . . as well, the problem isn't pinned down to simply Creative's hardware, but ASUS, Auzen and HT Omega have had the same issues with certain applications . . .
What happens - the audio processing in Vista is moved outside of the OS kernel, so the audio calls from the software are done at the application level . . . not the hardware level. Which means that Vista technically "interprets" the calls for the hardware and then passes the call onto the driver, which can result in strange behaviour (intermediate loss of channels, changing from 5.1 to 2.1, etc.) - unlike in XP where applications had direct access to the audio system.
Strangely enough, applications that are integral to the OS once installed (i.e. Windows Media Player or Media Center) don't have these issues as often, it's actually very rare . . . and if you're using onboard audio instead of a card, the problem seems to never occur . . .
My best advice - make sure you keep Vista as updated as possible. As well, make sure you've updated the OpenAL drivers. If you can, try to research and use only multimedia software that supports OpenAL (you'll have much fewer issues), instead of having to rely on Vista's 3 primary audio APIs.
If you'd like to read some more of the nitty-gritty as to what Vista APIs do what, check out these links:
Vista Audio API overview
Windows Audio Session API
MultiMedia Device APU
Endpoint Volume API
Device Topology API
More info is available on Vista's audiostack on msdn - just browse around.
As of now, my best advice would be to patiently wait and see how the daniel_k drivers hold up . . . but if trouble starts brewing again, you might want to attempt to start experimenting with different official driver packs . . . some seem to work better than others
Like I said, just figured I would try to bring a smile to some poor sods otherwise probably dismal day fighting a Creative problem. We all know how it sucks troubleshooting something theres seemingly no answer for.
Well - we have answers here!
