Haven't tried to capture audio yet, but for the distortion, I am guessing you are talking about crackling kind of sound, like interference. Things to possibly look at is the priority of the modules that supply the sound. I have had problems in the passed(not my current via8235) with dma clashes, or not dma enabled for the card. Also with xmms not having enough priority that the sound keeps being interrupted on small intervals causing a crackling kind of sound. Another possibilty is the sampling rate. I unfortantely don't now much about this implementation and therse are only theories. Some time in the future I will go look at the source when I have time. Tinus |
