I have a T3620 running Win 10 Pro and its worked brilliantly for nearly 4 years now. A few days ago I tried to install a PCIE card to provide me with 4 extra USB ports - the card seemed to be recognised and it looked like the supplied drivers were installed, however I couldn't get any USB device to work when attached to any of the ports. I also noticed that my audio seemed to have stopped working - I have a Dell AS501 sound bar plugged into the rear speaker jack and a Roland headset plugged into the front audio jack. There is now no sound coming from either! Prior to installing this USB card I had been happily listening to TV programs etc via the Roland headset for a long time, although I rarely used the Dell sound bar.

I have now physically uninstalled the apparently defective USB card and as far as I am aware also the drivers that came with it. However it has made no difference to the problem with the audio jacks - I know the headset works because I have tried it in another machine. I have also tried all sorts of things to see if the jacks have been muted or whatever but nothing has made any difference. I have noticed that when I go to Sound in Control Panel and click on Properties and then on Speakers/Headphones (which says 2 - Realtek Audio) and has a green tick by it and I then click on Test in the Properties window I see the green vertical bar opposite Speakers/Headphones in Sound shimmers like it is playing audio for what would be a reasonable 5 sec or so test period!! See image below.

 

 

 

 

 

 

 

 

Can anyone suggest what I could do to fix this problem or reset the sound jacks to their default state please?
