I have Creative 2.1 speakers which sounded great with my previous onboard Realtek AC97 video card. My previous motherboard sounded even better, but I cannot remember the onboard audio card.
I recently upgraded my system (i5) and have a P8h61-MLE Rev 3 board with the same on-board ALC887 High Definition Audio. I have found the sound quality to have dropped much more than it dropped between my first two boards... I am in the same position and I am looking for a decent audio card.
I have looked at driver and BIOS updates, but I am running the latest releases.
I have also changed the settings in the audio control pannel, but nothing works.
