Sorry to bump an old thread, but has anyone found a reliable solution to this? I'm having this exact same issue and it's infuriating. When plugging the headset into my ps4 it works perfectly fine until the startup sound plays, then the microphone auto mutes itself and I'm unable to unmute it since the ps4 doesn't support the built in button. I'm using the Void RGB usb (model # CA-9011139-NA) if that helps at all.
Edit: I managed to solve it by plugging the headset into my computer and holding the mute button until the mic defaulted to active when first plugged in, then it started working on my ps4.
