Hi,
I get a high pitched whine in the right ear of my barracuda headset while connected via the dongle. If I connect via an audio cable, i don't get the whine. It started a couple of days ago.
I’ve tried updating firmware, but I cant seem to find a firmware for my headset: RZ04-03801. I tried RZ04-03800, as it was close, but it didn't seem to detect my headset.
I’ve isolated it to the dongle - with dongle in, I get the whine, without I don't get a whine. If I set volume to zero, on both the headset and the PC, the whine is still present. But as soon as I disconnect the dongle it goes away.
Any advice, or things to try?
