Hi Buyaka,
Glad it’s not occurring anymore! If this happens again, let us know. My guess is that this is more of a hardware and/or driver issue, since it occurred on builds as well, but I can’t be certain. If it does start happening again, make sure your headphone/speaker cables are all plugged in all way, and include your dxdiag as well as any additional details you may have in a reply here. Thanks!
