It's not Windows, Corsair - it's your buggy app! I even found a Corsair help page that implies Windows is to blame. I'm amazed that (1) iCUE would even mess around with per application volume settings (why? could you please leave system settings alone?), and (2) that this bug appears to have first been reported 5 years ago and still not fixed. (After some experimentation I suspect it has something to do with the EQ feature, but I'm not entirely sure - it is not perfectly reproducible.) I know that it's iCUE doing this because it always happens if iCUE is open, and never happens if iCUE is closed. It took me a while to figure out what was happening - I was worried my headset was dying or something. It brings the volume down for all apps, and does that repeatedly after a few iterations of this, the volume becomes so low as to render the headset basically unusable.

I hit the same bug with the latest iCUE software (v4.11.274) and a brand new Virtuoso headset with latest firmware (v0.17.149).īasically, iCUE messes with per-application volume settings for no apparent reason.

I'll have to find time to test more and see if I can consistently trigger it sometime. I don't really care if a CUE voice prompt is difficult to hear, while it's far more important that I'm able to hear the people I'm talking to on Mumble. Since this sounds rather hard to diagnose and properly fix, perhaps an easy workaround would be to add an option that prevents CUE from adjusting other applications' volumes? If it's buggy, or causes other programs to be buggy, I'd rather not have it. So, at a guess, this is when the two clash and try adjusting volumes at the same time, then failing to restore properly. I also have the voice prompts enabled in CUE, which does similar adjustments.

Specifically, for me, it seems to be mostly when I have Mumble running at the same time - when has the option to 'attenuate other applications while users talk'.

It seems to occur when there's another program that also sets volumes. I've been experiencing this too, both on old 1.16.42 and 2.4.66.
