I recently bought a Xonar DX sound card from OC, and, after installing drivers etc, it is quiet and crackles on bass notes. My headphones (Sennheiser HD280) are also new - and work fine either with the onboard (motherboard) sound or my brother's PC. So I can safely assume it's the sound card.
Is an RMA necessary, or am I missing something obvious?
