change your phone codec into aptx, aptx hd or LDAC in developer mode. hope that may help. i noticed some difference, from SBC.
yes,
there is work around for that.
1. start game with mic off. team speaker should be ON.
2. then turn OFF speaker.
3. turn ON mic only.
4. now turn ON speaker.
mic and speaker should be working fine now.
but you will get lower audio quality than usual.
at least this works for me.
try and replay.
