Stereo audio not working but hands-free ag audio works perfectly?

My headphones are connected properly, and have been working fine up till now. Now, whenever I connect my beats to my laptop the hands free audio is in use (I can tell because it has a constant crackle like a cellphone call) and I can’t switch it back to the stereo audio though my device’s settings. Whenever I try to change the default speaker in any app to the stereo audio, it switches from the hands free audio but no sound ever gets played and I can’t hear any audio playing anywhere on my computer through the headphones. I’ve made sure that the volume is up, so I know that the audio isn’t just muted on my computer. I cant find anything online that can help with this. Please help if you can.
