I updated the iCue (october 8th 2020) and now the problem of mic muting (and never unmuting with iCue on) is happenning again.
I just downloaded the older version of iCue that the Corsair Staff posted before on this thread, and now is working. I didn't restart my computer, so i don't know if the problem will come back when I restart it. I have already had enough headache for today.
I really hope you guys fix this problem. This headset was kinda expensive (void pro), and I really liked it at start. But now ? With SOFTWARE problems ? I am really disappointed.
