The RightMark Audio Analyzer suite is designed for testing quality of analog and digital paths of any audio devices, be it a sound card, an MP3 player, a consumer CD/DVD player or an acoustic set. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. The latest version of RightMark Audio Analyzer can be found here.

The MSI P67A-GD65 audio performs on par with all of the other boards that we have tested. The stereo crosstalk was lower than on the ASUS P8P67 Deluxe and the ECS P55H-AK and right on par as the ASUS P8P67 Deluxe. Ultimately though, all of the boards have been more than suited to meet my audio needs.
