I bought RME UCX a month ago. I´m very happy with this purchase despite some problems im having since then. Nobody could help me out with this, so please let me know how to solve it.

1-First of all, what´s the correct way to turn on and off the audio driver?
2-Sometimes the audio output keeps jumping in the Software Playback Session- Keeps jumping randomly from channel to channel.
3-The Softwares seem to be somehow assigned to different channels of the Software Playback Session.
4-Everytime I connect the Midi Cable to the UCX this DIM Button lights up and the Main Volume goes down, this happens a alot. (This happens with the Midi and Remote)
5-Midi and Remote somehow dont send information for ableton.

I´ve been searching for the topic 1/2/3/4 and cannot find a answer for it. Topic 5 is something that has been told to be automatic but seems not to be working.

Thank you,
Best Reguards
