IDT Audio driver for DELL E5520 @ Windows 10 (problem with Skype)

I have DELL E5520 (service tag HDPXLQ1) and recently I installed Windows 10 x64 on it. In general everything works fine and only problem is sound in Skype !

The last OS officially supported for E5520 laptop is Windows 8, therefore the latest IDT driver suggested for download from DELL is 6.10.0.6324.


The problem is Skype the following:

- microphone works fine

- ringing works fine

- what doesn't work is I can't hear the person I try to talk with (even though ringing works !)

I tried to search the Internet and found that indeed, IDT Audio is the pain in the ***. And I've found exact problem descriptions as my on HP forums, probably because many IDT Audio stuff was installed to HP laptops. On HP forums there are some suggestions like installing IDT Drivers for other chips or even there is some info thar HP took over to support some drivers from IDT.

Anyway, I would highly appreciate if somebody know how to solve the issue. Either if there are some compatible drivers or if there is any workaround. On HP forums there was suggestions to set 48 KHz/24 bit as default - this doesn't help. As far as I understand, the issue is related with some sample rate / bitdepth Skype tries to switch, because ringing works, everything else works except Skype. 

If I don't install IDT Audio drivers, then some Microsoft driver is installed for output, but no microphone in the system until IDT Drivers are installed :( Thanks in advance.

The last OS officially supported for E5520 laptop is Windows 8, therefore the latest IDT driver suggested for download from DELL is 6.10.0.6324.

I don't think that is correct, or at least I can't find that. Unless I missed something the last audio driver for the Latitude E5520 was the IDT 1.16.0 (R297613) for Windows XP, Vista, & 7. Try installing it in compatibility mode. (Completely remove any other audio driver first except the Windows native driver "High
Definition Audio Device".)

1. Download and save the audio driver to your desktop or any convenient location on the hard drive..
2. Double click on the new folder to extract (unzip) the driver files.
3. The extractor wizard will create a new folder for the driver files. It will be at "c:\dell\drivers\xxxxxx". Write down the exact location that the wizard creates.
4. If the driver begins to install automatically, halt (cancel) the installation.
5. Browse to the driver files on the hard drive (the location you wrote down).
6. Find the "setup.exe" file.
7. Right click on setup.exe to open the context menu.
8. Select the Properties.
9. Select the Compatibility tab.
10. Check the box "run this program in compatibility mode for"... Win7.


If installing the IDT driver does not help you should consider reverting the laptop back to the operating system in which the audio did work correctly if you need to have the Skype functionality.

Yes, you are right: the latest driver for E5520 is IDT 1.16.0 (R297613). Just my version number is different, as it's specified in driver properties in Windows.

I didn't have Windows 8 on my PC, so I don't know if this problem started from Window 8 already (as there is not listed this driver is compatible with Windows 8 even !). So, I've updated from Windows 7 (everything was OK with Skype) to Windows 10.

I've tried some other newer drivers, but it says it's incompatible with my particular IDT chip.

Just my version number is different,

If your driver is the IDT 6.10.0.6324 (R297811), it is not the same as the R297613.

Actually no - I have double-checked and I confirm that after installing of DRVR_WIN_R297613.EXE - my driver in the system is 6.10.0.6324
