LinuxQuestions.org - USB Stereo + ALSA

I have a USB Stereo system, from philips its the C577 model, it supports pc link via usb for audio output.

I run slackware linux, and the kernel reconizes the Audio device.
as snd-usb-audio (i think) and there is also a listing for it
in /proc/usb/... when i run xmms or anything is supposed to output sound
i get nothing, i assumed from the usb audio HOWTO pages it supposed
to be set up automaticly.

When i do cat /dev/dsp i get alot of stange console output that look like hollow boxs [][][][][] that goes on forver until i break it. is this normal?

anyhow i installed ALSA but i cant run any of the tools. alsamixer for example i get this error:

alsamixer: function snd_ctl_open failed for default: No such file or directory
anyhoo i know i need to set up my modules.conf to set up my audio but i tried many diffrent times with no success this is my moduels.conf:

alias char-major-195 nvidia

alias char-major-116 snd
alias snd-card-0 snd-usb-audio
post-install snd-card-0 /usr/sbin/alsactl restore
alias char-major-14 soundcore
alias sound-slot-0 snd-usb-audio
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
post-install sound-service-0-1 /usr/local/bin/sfxload -c30 -r30 synthgs
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

and this my moduels.devfs
