I've ran into a pretty terrible issue and believe the cause is Windows 7 itself. I've checked through just about every site and thread looking for a good fix on this and there doesn't appear to be any.
I am working with:
Windows 7 Ultimate x64 OS
Auzentech X-Fi Forte 7.1 sound card
Logitech Z-5300 5.1 speakers/analog connection
The issue is that 'true' 5.1 sound will not play through all of the speakers of my 5.1 setup. Only certain speakers get used, depending on how I have them hooked up to the Forte. Basically it's only using 2.1 rather than 5.1. When I first installed my Forte, I was having no issues until I installed a few Windows Updates - after I restarted, 3 speakers were not working. No issues through Headphones, those work and sound great.
I am using MediaMonkey and WMP as my main test programs, as they used to work before without issue so I see no reason not to. Playing high quality MP3s'. Games and DVD movies work through all 5 speakers, but that's about it. The speaker test in the control panel has all speakers giving the properly sound locations and all speakers respond correctly when I hit 'Test'. That's the thing that really gets me.
I've done A LOT of troubleshooting, here's what I've tried to basically limit it to being a Win 7 jack assignment/configuration issue:
1) Checked connections on back of the card and speakers several times.
2) Reinstalled sound card drivers several times/played with settings in control panel/device manager.
3) Re-inserted sound card a few times.
4) Installed my old Creative SB Audigy card and hooked it up. Ran into the exact same issue.
5) Re-formatted entire PC - installed sound card drivers - same issue.
6) Everything IS configured properly.
What the ____ can you do more than that?! I went to the extreme on this issue and even that didn't work. I'd say this basically limits it down to being something to do with Windows 7.
I can't figure out why it was working when I first installed my sound card, and for about 2 weeks after that it was fine. All of the sudden, they stop working. I can use CMSS in X-Fi(or Matrix Mode on the speakers) to run 5.1 'Stereo' sound - which is basically the sound of 2 speakers playing through 5. This is not the same as True 5.1 and the sound quality is terrible. Even running 2.1 is better than that, but I bought a 5.1 system so I could use it, not have it look pretty.
Here are some threads where other people have ran into the same issue, with no apparent resolution:

I'm just wondering what I could do next...why is this not resolved? I am almost 100% sure this is something to do with Windows 7. I will go to great lengths to prove that, even installing Windows XP as a test. Hasn't anyone tried to get Full 5.1 from their Z-5300's and Z-5500's etc...? I know it's just not me. Any advanced users out there have an idea? The basics aren't going to work on this issue.
