Need help please

I just recently bought a Blackshark v2 pro for my pc and ps5 and it works just fine but I use a fifine K688 microphone for both pc and ps5 which has an aux port on the back and I’ve used a wireless turtle beach headset but the problem is when I connect my headset to the ps5 it will change both input (sound) and output (microphone) for the PlayStation to the headset why can’t I just use the input for the blackshark and output as my fifine mic??? And I have used the aux port on the back but get no audio and I’ve used a headset with the aux and works just fine Plz help (NVM I FIXED MY ISSUE IF ANYONE WAS GOING TO REPLY THANK YOU AND HAVE A GOOD DAY)
