sorry my english is very bad!

I've a Problem with my Asus Xonar DX.
I pick up the sound analog from the 3 rear plugs (fron L/R, Rear L/R and Cender/LFE).
When i test with: speaker-test -D surround51 -c6
i get the perfect noise from each speaker

ndre@ubuntu904:~$ speaker-test -D surround51 -c6

speaker-test 1.0.19

Das Wiedergabegerät ist surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Samplingrate auf 48000Hz gesetzt (gefordert waren 48000Hz)
Buffer size range from 16 to 87376
Period size range from 8 to 43688
Using max buffer size 87376
Periods = 4
was set period_size = 17480
was set buffer_size = 87376
0 - Vorne Links
4 - Center
1 - Vorne Rechts
3 - Hinten Rechts
2 - Hinten Links
5 - Low Frequency Effects (Subwoofer)

when i try to playback a normal stereo mp3 file i get a 4.0 sound.

But i want to have at least a 2.1 sound better a 5.1 sound!

I read in many forums and try a lot but -sorry- i don't understand all the things.

Pleas what can i do to get the 5.1 sound when playing a 2.0 file?

pleas see my alsa-info.txt

thank you very much
