I unplugged my speakers, briefly plugged them into another device to check that it was working, and when I plugged them into my PC again, no audio. I've been troubleshooting all day and still stumped.

 

Under sound, it displays:

 

[Grayed out:]

Speakers

High Definition Audio Device 

Not plugged in

 

Digital Audio (S/PDIF)

High Definition Audio Device

Ready

 

[Grayed out:]

Speakers / Headphones

IDT High Definition Audio CODEC

Not plugged in

 

[Grayed out:]

Headphones

IDT High Definition Audio CODEC

Not plugged in

 

[With green checkmark:]

Digital Output (S/PDIF)

IDT High Definition Audio CODEC

Default Device

 

I tried setting "Speakers / Headphones" to default, but no luck; since the computer doesn't seem to agree that they're plugged in, it won't let me set as default. When I try to play audio, the "Digital Output" lights up the sound levels, but, obviously, I can't hear anything.

 

Other possibly relevant information:

 

- Installed Windows 10 months ago and never had an audio problem, so this seems unlikely to be related to the update.

- Didn't unplug or mess with anything except speakers when problem occurred.

- I have unplugged / plugged in these speakers dozens of times in the past with no issue until today.

- Cables secured, not dirty, and nothing seems to be damaged.

 

Any ideas what this could be and how to fix it? Getting desperate.
