I suggest the same as Giso. If you are learning music, you might want to use other audio apps at the same time anyway. So go for the JACK Audio Connection Kit. I've used it ever since I started with Linux. I don't have an RME, but I have a multichannel audio interface.

I have the Multiface II, and it's nearly impossible to address through raw Alsa without some deep kung-fu. Though Jack you should be able to see all of its i/o's and use it with MPlayer or whatever you want.

The multichannel RME devices do not support being opened with less than full channel counts or with the wrong sample format. Any approach that ends up using plughw:CARDNAME should work just fine. For some, using such a device name will be deep kung-fu, for others not so much. And it may depend on the application how easy it is.
