Bootcamp Sound Problems

So I've been having a problem lately. When I'm in Mac OSX, my internal and external (3.5mm jack) speakers work fine, but in Windows 10, only the external ones work. When I try to listen to something with just my internal speakers there is no sound that comes out. There are also two different options to choose from when choosing a sound output "Speakers (Cirrus Logic CS4208 (AB 94))" and "Digital Audio (S/PDIF) (Cirrus Logic CS4208 (AB 94))" both choices do not output any sound.

Any help is appreciated.

If you choose "Speakers (Cirrus Logic CS4208 (AB 94))" as the output device, the sound should work. The Digital version is for S/PDIF and is only used if you have an Optical receiver at the the other end.

This may be a silly question, but do you have your speakers muted?

I currently have it set to "Speakers (Cirrus Logic CS4208 (AB 94))" as the output device, and it is at 100 percent volume and it isn't playing sound from the built in speakers only on Bootcamp. It used to work fine.

No recent hardware changes. I may have possibly updated windows. I think they stopped working a few weeks ago. I haven't really noticed though because I have external speakers at home, but when I went out and had to use them, they did not work, but in the Mac OSX side it worked fine for that occasion.

Have there been any recent hardware changes or Windows Updates?
When did the internal speakers stop working?

Do you see a faint red light in your earphone jack? What year/model is your Mac (do not post the serial number)?

Can you run a SMC and NVRAM reset and test?

On the Playback tab, when you are playing any audio, do you see the level meter fluctuate?

Yes it does. I am also able to hear it when I plug in headphones or speakers. Only the internal ones aren't working.

You do not have a hardware issue, but just a driver issue. You can try to re-install the driver.

Okay, so I found something weird

My internal audio actually works when I use Edge or video/audio files stored on my computer, but when I use Chrome, it only works if I plug in external speakers.
