That's the thing I tought about 10min.. Imagine that: You have an embedded device with a very good codec driver (all codec controlls are available) but the hw-guys didn't connect all the in-/outputs. So switching those controls are useless too. IMHO this is exactly the same thing here. Regards, Marco
