Pops and crackles when using Emu 0404 USB - Page 5 - Head-Fi: Covering Headphones, Earphones and Portable Audio

You may know this already, I don't know how many times you've rebooted......but if you reboot without the 0404 USB connected, don't load any player applications at all, and immediately go into Sounds and Audio Devices, what does it show?

Jiitee, should he try to run dxdiag at some point, just to be sure that something isn't goofed up there that, for whatever reason, Foobar can get around, but the other playback apps cannot?

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.

I guess what bugs me is that your onboard isn't being seen by all the other playback apps, which seems to be more of a Windows problem.

Let's try this....click Start>Run, then type dxdiag in the box and click the OK button. Select the option to not connect to check for signed drivers (I cannot recall the exact wording) and let dxdiag start up. You should then see a Sound tab, and when you click on that tab, you can then click the "Test DirectSound" button to be sure that the Sigmatel drivers are all OK.

I wonder if installing a new driver could possibly have caused the other apps not to recognize the onboard sound, though, but first make sure that the Sigmatel works fine in DirectSound mode.

I'm guessing here, but it might be that the new Sigmatel driver installation didn't configure properly for some reason.

What I meant was more along the lines of did you stop or disable any services as jiitee mentioned in post #7 of the thread.

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

Well, that says to me that the Sigmatel driver installation was goofed up.

I'd suggest going to the Sigmatel page and finding out exactly how to uninstall and reinstall the driver. Sometimes installing a new one without following some explicit directions for uninstalling the previous one will result in big problems.

You had to download that driver installer from Dell, correct?

EDIT: Well, I see that Sigmatel sold out their PC audio device business, and that the Dell page for the driver sure doesn't give any info on install instructions.

Jiitee, do you think that maybe he should do a System Restore back to a time when he knew that that the onboard audio worked with WMP? I have to believe that something goofed up in the driver update that is now causing him problems with DirectSound, and that might be the most direct way to get out of the mess?

Halqyon · 03-01-2008, 08:53 PM

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

sejarzo · 03-01-2008, 09:23 PM

Yes, restart.

Then immediately go into XP's Device Manager when your system boots up. Click the + to expand the "Sound, video, and game controllers" section....see if there is a problem noted with the Sigmatel driver. I don't know if there will be a valid rollback option available there, if you've installed and reinstalled a new driver (never had to do that myself!)

I am confused a bit by the page for your notebook at Dell......did Dell supply some with a Creative Audigy internal card, and others with the Sigmatel? I can only get to the page that shows drivers for all XPS 1710M's which show both. You probably get to a support page specific to your serial number, though, that shows only the drivers required for your specific hardware, maybe?
