+1 for this issue...
New headset today. Mic mute LED turns red/green as you'd expect. But will always transmit Mic audio whilst iCue is running. All software/firmware up to date.
Massive security risk for me and my line of work. A official Corsair response to this is needed within 7 days or I'll have to return the product. I cannot use this product for work until it's resolved.
Cheers,
