You can also use the Emu 0404 USB, by connecting an optical cable to the HDTV-cable of the 360, an extremely easy solution, that in turn gives you great sound quality.

Just to be clear; I used the newly released Emu drivers for Vista: E-MU: Downloads

Nope, wasn't an option, had heard good things about Vista from my brother, so I opted for Vista instead. I made this thread to show people that Vista + 0404 does work, and so far I haven't experienced any problems.

A little over one week ago I received my brand new 0404, naturally this was exciting, but things went downhill fast (used Windows XP). I heard crackles and pops when I played music, so naturally I headed over to this forum for som advice. There were lots of suggestions on how to fix this...

I did that, but there are no errors being reported. I'm going through the troubleshooter now. But do you think formating the pc would correct things? I think I'm going to buy Vista soon.

Yeah, some 1710's came with the other soundcard, I chose the cheapest one :S I can't rollback the driver since it has not been backed up, but maybe if I uninstall it and then reinstall, then it will work?

Hmm, just installed the driver again, but it still doesnt work. Maybe I should restart?

I did what you said and this is what it said : DirectSound test results: Failure at step 3 (DirectSoundCreate): HRESULT = 0x88780078 (No driver)

I'm using System Restore to check what I've been installing: I've installed a couple of drivers, a wifi driver, new bios and a driver for the Sigmatel soundcard.

Windows Audio is running, maybe I should restart it?

Yes the 0404 is disconnected. In the control panel it still says no devices....

Nope, not using ASIO, its set to DS : Sigmatel Audio.

I enabled the onboard soundcard but Im not getting any sound from the speakers when using WMP (same with winamp or youtube), but when I use Foobar i get sound....

The services are started, and I have disabled my onboard soundcard, should I enable it?

It says that there is no audio device, everything is dimmed, cant change anything. Also my EMU control panel is lit.
