I uninstalled and reinstalled the newest driver from Dell site, 3 times. NOTHING.
I contac IDT and got this reply:
We suggestcompletely uninstalling the audio driver via Add/Remove Programs and Featuresin Windows control panel. Then (clean) install the latest audio driver,"System Software" and BIOS available on your computer maker's website. Download the most current driver specifically listed by the computermaker as supporting the *exact* model number and *exact* OS version of thesystem loading the driver. If either the computer model number or the OSversion listed as supported do NOT match the system being used, then the driveralmost certainly will not work properly. Note that certain OS versions may notbe supported by your computer maker (for example, Windows XP is not a supportedoperating system on many new computers).If issues persist after this, please contact Dell's technical support group forfurther assistance.IDT is not allowed to provide drivers to users/consumers per the request of thecomputer manufactures, who desire consumers to contact them. Please contact themaker of your PC, notebook or motherboard for a driver or driver update. Hereis a link with several computer maker support links: http://www.idt.com/?app=knowledgebase&contentID=3640&parentID=3640&parentPath=1210-3638-5603-3640If you are not able to work the audio controls or achieve the desired setup,contact your computer maker as the feature you desire may not be available oryour setup may not be compatible with the actual hardware. Grayed out items arenot supported because either the computer hardware does not support it or thecomputer maker chose not to enable it. IDT is not able to modify drivers forconsumers, only for the computer maker. If looking for a different operating system driver (like an upgrade to Win7),please see your computer maker’s website for support. If they are not offeringthat operating system driver, it is likely that the computer maker is notsupporting it on your model, and thus IDT cannot provide it. Please note thatchanging the operating system may violate your warrantee from the computer
Does the audio work okay? I mean can you hear sounds when you play an audio file?
When you have the IDT driver installed, can you see the regular Sounds control panel? Looks something like the top part of this, where it says "IDT High Definition Audio Codec":
integIDT High Definition Audio Codec - vertion 184.108.40.20624.
Could that be the wrong driver? I went to the E5520 downloads page (Windows 7 64 bit), where the version of the IDT driver is 1.16.0, A03 (R297613). Have you tried that one?
I did a search for 220.127.116.1124 but got "no matches" here on the Dell site. When I googled it the number matched an old Sigmatel audio driver.
