I've never had any issues with the auto detect and MP10a cards.

If you're having an issue then it's either the switch, patch lead(s) or the lan port on the card.

What make/model is the switch you're connecting to?

The cisco switch that's set to 10/half, what happens if it's set to auto?

Your audio issues will be due to the 10/half setting.
