Audio delay when playing Delta Force

Hi, so I have an issue with my BlackShark V2 Pro 2020. When I start playing Delta Force(fairly new game), every other audio on the PC (spotify, youtube, discord notifications etc.) are delayed for approx 2 secs, but the game audio isnt delayed, so there is nothing to really worry about. But now when I am playing the game it still doesnt have the delay, however voice chat in the game does, so it results in me not hearing half of the short important words like yes, no, on my mark etc. This happens only when using the 2.4 Ghz dongle, once I connect the headset via 3.5mm cable it works fine, however when I use the cable the audio sounds really bad. btw I am using synapse 4.
