Which patch did you try? Some are programmed not to react to audio at all. What audio source did you connect and how? If there is some soldering or other manufacturing related problem that slipped through our testing and causes your audio input to malfunction, we would replace or repair the board. > Furthermore, the audio output is extremely noisy regardless of the > volume sliders or the presence of audio input.

We indeed have rather high noise levels on the audio output of the board, but since the audio output is little more than a easter egg feature for hackers, we did not give a lot of priority to it so far. The amount of noise seems to vary depending on what device is connected to the output - sometimes it is very noticeable, and sometimes barely. For example, connecting headphones to the line output (which it is not designed for) drowns the signal in noise and distortion. Since the ML401 board that uses the LM4550B codec exhibits significant noise on the outputs as well (at least on my board), I suspect the codec chip may have something to do with that. I have just requested samples of WM9707, we'll see if it improves things (it should be an easy PCB rework btw). BTW, Adam, do you have other AC97 codec chips you could recommend?
