Blackshark V3 Game/Chat Mix Not Working

yes 

I tried everything. It does not work on discord. Tried SONAR, nope. I gave up. Also you cant use the wheel for the chat/game mixer. Razer should fix this.

Not to mention I tried every possible port on my PC

Use different USB PORT. Try every port available/

Additional Observation Regarding Chat vs Game Endpoint

I would also like to add an important observation.

When I switch Discord output from BlackShark V3 Pro – Chat to BlackShark V3 Pro – Game, the audio becomes noticeably louder and more stable.

While using the Chat endpoint, the volume sometimes appears reduced or inconsistent. Additionally, when I disable and re-enable the THX APO 4 component, the Discord volume suddenly increases significantly. This suggests that the APO layer may be actively affecting gain levels and possibly entering an unstable state.

With the Game endpoint selected:

• Audio levels are higher.

• Audio remains stable.

• I have not experienced the sudden audio drop so far.

This behavior suggests that the issue may be related specifically to the Chat endpoint and/or its interaction with the THX APO processing layer, rather than a USB or hardware disconnection.

Please advise if this is a known issue with the dual-endpoint configuration or firmware.
