Windows 10: Speakers have stopped working after an update

Like the title says, my logitech z533 speakers have stopped working after a recent Windows update, and I've been on chat with support all day and I swear they are making things worse rather than better. Please help.

External speakers stopped working

Two days ago the external speakers (cheap Altec Lansing speakers) on my Dell laptop just stopped working. At that time, they were appearing in the device list. But I couldn't get them to work. The built-in speakers in the laptop were working. That night I restarted the computer to install some Windows updates. After restarting, the external speakers still were not working. Internal speakers are still working. Now the externals don't show at all in the list. I connected these speakers to another computer and they work fine. I connected a flash drive to the USB port to which the external speakers were connected to test the port and it works. Unfortunately, I don't have anything handy to test the 3.5m headphone jack. (These are 2-connector speakers, a USB and a 3.5.) What to do from here? Everything I read says update the driver but these speakers don't use a driver. I'm afraid if I buy new speakers it will be the same problem. Why won't my computer recognize these speakers? I can get by with the built-ins but they are so tinny-sounding.

 

Bose Speakers Stopped Working

Your latest post says "Audio". Is this what you're mentioning? If not, then try this: Is your Bose Speakers listed here?

If so, select it, and try playing audio.

 

External speakers stopped working

I'm actually using a hub. The speakers were working fine in this USB port on this hub combined with a headphone jack on the computer. Have been working fine for months. And then the speakers stopped producing sound. The power light is still on on the speakers. You can even hear a faint click from the speakers when you turn them on and off. And the speakers work fine/produce sound on another computer. There was no update immediately prior to the problem's first occurrence as far as I know. Current build is 19045.3693. Well, that points to the headphone jack. I was hoping there was a way to pull up a list of the jacks on the computer. Or maybe somebody has another idea. I have a pair of headphones, but the plug on these is much larger. Adapter, maybe?
