Audio
For audio testing I run all of the motherboards through Rightmark’s Audio Tester. This benchmark outputs audio out and then right back into the microphone input to test an audio cards overall performance. This is the benchmark that we see the most variance between motherboards because Intel doesn’t include a sound card in their chipset (other than HDMI audio). Generally the more high end a board is the more than can afford to invest into better audio cards as well as focus on isolating the onboard sound card from the rest of the motherboard. In the case of the UD4H I didn’t really have high expectations simply because this is a mid-range to budget board. Even so I was able to compare it to the general market motherboards from Asus. The UD4H performed very well against the other boards in its price range. If you are heavy into audio quality you should plan on adding a sound card later, but I think that most people will be happy with the UD4H otherwise.
