There is a deep intermittent buzzing sound from my Samson SR850 headphones. I've checked with my phone and it isn't the headphones. I can't seem to find a pattern with the noises, one second it's working fine, then there is a buzz. It seems to happen with the microphone also when it's plugged into the front-panel connectors along with the headphones, however there seems to not be a rear headphone connection for my motherboard, unless the software just isn't bringing up the option. Any help would be appreciated, as Gigabyte have offered to look at it for RMA, but I can't work without my computer, so that's a no-go.
