My wife has two pairs of headphones, a set of Bose Noise Cancelling Headphones 700, and a set of Galaxy Buds. Problem is these headphones, like many, have two Bluetooth endpoints. A headset endpoint (very low quality but very fast) HSP, and HFP a full quality headphone endpoint(higher latency but higher fidelity). When you start 7Dtd on either my computer or hers, it is fine. However, once you join a party with another player the headphones switch to HSP mode and the quality goes to dirt. We are both on windows 11, fully up to date. I have had this issue since alpha 19. Now to be clear we have tried disabling chat in windows, disabling voice chat in 7Dtd, and once you join the party, turning the headphones off and on, to try and force them back to HFP mode. I don't know of a way in windows to switch this to force it to be one way. figure there might be one but, I haven't discovered one, and we only have this problem with 7 dtd, across multiple machines. I am a computer scientist and was told by your support team to post here, and if there is no fruitfulness to make a formal support ticket.
