Hi! I recently got a new Halocode (MFF-K00-01) and it started making these very high pitched sounds. It kind of sounds like sizzling. It is not that loud but loud enough to notice it. I was wondering is this constant high-pitched sound normal? I have tried updating the firmware but that didn’t help. I also think that this runs a little slow for a simple program and I was wondering if the sound is affecting the performance.
