Hey Janina,
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 hope this is a viable solution for you setup.

Hi,
I've recently gotten my RME Multiface up and working quite
satisfactorally with current Linux kernels. I'm very happy, especially
as I had a long run of it not working for some reason I never teased
out.
So, I find I can aplay and arecord, and I can use ecasound, and a few
other cli tools.
But, I can't use mplayer. Am I the only one? Anyone else tried mplayer
on the Multiface?
For cli tools mplayer gives me the ability to pause, or move backwards
and forwards through the audio file. This is important to me because I
learn music these days by ear.
I know one can do this in the gui, but as a blind user the Linux gui
audio apps aren't particularly friendly in my experience. Besides, it's
so terribly simple, if rather imprecise, to use spacebar, left-arrow,
and right-arrow.
The error I get:
Opening audio decoder: [pcm] Uncompressed PCM audio decoder

Meanwhile, aplay and ecaplay have no problems. So, I thought I should
ask if anyone else has experienced this before reporting to mplayer
devs.
TIA
