[LAD] 4 Stereo channels ADAT on EMU1212

Hey everyone. I hope there is some bright minds on this mailing list who can help me. EMU1212 output 4 differen stereo signals throug ADAT plauying 4 different sound streams simultasniosly. The card is installed and alsa recognises it. aplay -l lists three devices on card 0 device 0 has 32 subdevices. device 1 is missing device 2: has 8 subdevices and is named something with FX controller Device 3 har 1 subdevice *sury i dont have the real output at the monet* In alsamixer (playback) I can select a souce for each of the 2 analog outputs and each of the 8 ADAT outputs from ADAT0-ADAT7 The sources include DSP0-DSP31 and ADAT0-ADAT7 and some more Natually i think that the 32 subdevicec in device 0 coresponed to the 32 DSP's in ALSA. But no matter which of the subdevices i try to guide mplayer ot aply through, it only plays through the sam DSP's DSp 0 and DSP1 are respectivly left and rigth channel, dsp 6 and 7 is a player e damped signal of one of dsp0 or ds1 and dsp8 is also playing one of DSP1 and 2 undamped though. the rest of the dsp's does not rout any music unless the souround volume is turned up. I Testeed this by listning on all the diferens outputs analog 1 and 2 and the 8 adat channels while chagin through the diferent sources., I can sucessfully send sound from DSP1 and or = to each of the outputs and therefor the physical output is working fine. But i am not able to use other DSP than 0 and 1 dispite what commands I give mplayer. e.q. mplayer -ao alsa:device=hw=0.0.x MUSIC_FILE I have tried combinations and all the devices device 2 and 3 returns an device error. What can I do ?
