Re: No sound using bluetooth headset (windows 10)
Connect your Bluetooth headphones to PC, my steps are on windows 10
Sound settings>Sound control panel(top right)>Recording tab>DISCONNECT the Headset of your headphones(Hands Free Audio) , set the inbuilt mic on the PC as the default device( for example mines the inbuilt mic on my laptop, Shows up as Microphone)
On Playback tab DISABLE the Bluetooth headset Hands free and set the Bluetooth headphones as the default device
This made both my headphones and mic to work in game
This is a windows issue and not an apex issue as far as I can tell, I had to play around a bit before i fixed it, Let me know if it works , Happy Gaming
