Recently, my SteelSeries Siberia V2 broke and I sent it for an RMA. They were kind enough to replace it for me with a V3. However, the USB sound card that came with the V2 (and noticeably improved the audio quality) was incompatible with the V3 - it made a constant screeching noise. Therefore, I had to plug the headset straight to the headset/mic jacks on the back panel. The sound was different, but this was largely due to the different headset. My problem is that whenever I move my mouse, I hear a slight sizzling noise. Perhaps something is interfering with the motherboard audio chip? Would a sound card fix my issues? My motherboard is GIGABYTE PH67A-D3-B3.
