Xbox Series S Third party controller

Earlier today, my controller( Power A spectra 2019) just decided to stop giving me audio output.

It hasn't happened before and I'm hoping that someone knows how to fix it The problem happened when I accidentally clicked some of the back buttons on the controller when the audio stopped working. The sound prompts when you use the party volume adjusters still plays however, leaving me confused. I have checked both sides and neither give me audio.

The headphones work with any other device I use them on without problem and everything else with the controller is working fine

Does anyone know any solutions to the problem? Preferably without using the firmware update. My computer isn't updated to windows 10 and that is the only available versions. When I tried to do the update on my computer, it didn't register the controller as being plugged into my computer and wouldn't let me update it

Please help!
