i just found your post as trying to find out why mine is also doing this and sometimes the mic also turns off and i have to power off and on again
Just wanted to say that I have the same exact issue here, at first I though it might be the USB disconnect issue caused by AMD that's been fixed in AGESA 22.214.171.124 but I'm on the latest version of my motherboard (Asus Prime X570-Pro) and the issues is still present. I'm also using the latest version of the headset firmware (3763 as of this writing) this is kind of annoying because I've noticed that when it does that, the mic does not "reconnect" correctly.
I'm using this headset for work and sometimes I have to "reset" (switch the headset on and off) for the mic to work properly because otherwise the other person i'm with on the phone does not hear me talk, that's quite annoying.
I just can't believe with this price of a headset, there is NO Update for 6 months now, this is unbelievable, and no respect for the customers!
