I am using your X5DA8/E and I connect my speakerset to the "Line out" (lime color) connector on the mainboard, but the output level of the sound via my speakers is very poor, even when I set the volume setting on my speaker and in the O.S. to maximum. Why?
The poor volume output is due to your using a non-amplified speakerset together with the non-amplified "Line out" port. You must use powered speakers to solve this issue.
