Razer BlackShark V2 headset does not get sound, but is unmuted in alsamixer and pavucontrol

I have sound coming from my integrated speakers, but not in my headset.

I've already tried alsamixer and pavucontrol and it's not working. I have a error message when I type pulseaudio in my terminal which goes like this:

E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: Échec de pa_pid_file_create(). 

I've serched a post on this but non of solution worked and it actually broke my brighness settings (still not fixed).

It can be the driver of my headset wich is a Razer BlackShark V2, but I couldn't find it on Razer's website.
I'm a bit out of ideas ...

My computer is an Asus Strix laptop (UEFI) and I have a dual boot with Win 10/Ubuntu on GRUB.

Ok for those who come in here in search of an answer: for now, in july 2021 there is no answer... The problem come from razer. Only the Kreken headset is supported on linux. So if you have a blackshark V2 like me or others Razer headset you just can't use it. :'(
