I think we're on the right track, though, as now we seem to have identified the culprit. I've tried the driver you mentioned, and virtually no difference. You can check the Event Viewer to see if there are any errors reported by Storport. Now, if it happens only on a specific drive, there may be a compatibility issue or the drive is failing. Or there can be a more up-to-date generic Intel driver that will work with this PC.

Here Win10 is not mentioned, but the driver may still work. I think normally it is not used if you have a driver from the manufacturer (Intel in this case), but I am not certain if Intel's storage drivers for this generation support Win10. Storport.sys is Microsoft's storage driver. My setup even works well in Windows 10 running in KVM on Ubuntu 20.04 on T520 Passing the whole 2nd USB controller as a PCI device to VM I hope you get your audio issues fixed, just giving my evidence in case it helps. Think Jabras have gotten extra exepensive (1/2 cost of T420 I guess) in the times of Covid and working from home. I'm under impression that if Skype under Windows is your goal you're better off choosing Jabra with MS in the name not UC. I've heard nothing but praise about them too. There also also exists wireless Bluetooth Jabras. There exist USB Jabras that plug into USB and also work as an external audio card similar to my UCA202 but also have a working microphone. Perhaps my cheap/simple microphone would work with it.Īlternatively if you need to do audio conferencing (and perhaps even if you don't) you may be interested to hear that I have heard high praise for Jabra headsets. There exists a similar UCA with a different name with phone preamp. It's missing 'phono preamp' I understand. Unfortunately UCA202 doesn't work for me to input audio from an external microphone.

Sound quality is better than with normal audio output jack. You basically plug your earphones or speakers into UCA202. It's got a USB jack and is powered over USB. This is a relatively small and cheap external audio card. Hi, I hope others help you better with this, for what it's worth I've got UCA202 connected to my T520.
