So far a real big "thank you" to you people!

I'll sum up what i did so far:

1. "cat /dev/dsp1 | aplay -r 8000"  worked, but the sound quallity was really bad and i had a delay of about 1 sec (with -r 16000 and -r 32000 i had this buffering problem "Pufferunterlauf" so it didn't work for me).

2. Installed "libsox-fmt-oss" and got sound with "sox -r 32000 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp"

I actually didn't have modprobe.conf, even tho as far as i have understood from other forums it should have been created. So i went and created one myself and pasted the modifications, don't know if it's the right thing to do, but i didn't come up with a better solution.

the "arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay -" works!

so i've got sound and it works wonderfully, thanks to everyone!

P.S.: about the question if its the dev1... i'm afraid i'm not really quallified to give you a certain answer, but it seems to.
