Sport x10 stereo audio not working on desktop

I’ve had my Sport x10s for a while now and they’ve worked great, but recently they started to disconnect a lot on my desktop, and now suddenly the stereo setting doesn’t work at all for them, so I’m stuck with mono audio on my PC.
This isn’t a problem on my phone, they play stereo audio completely normally, but for some reason I just get no sound when using the stereo option on my PC now, only the mono audio works which sounds terrible. I’ve tried doing a hard reset and disconnecting/reconnecting them multiple times, reset my bluetooth, gone into the audio device settings, but nothing has fixed them.
