No audio in Intel Haswell audio controller

Hello! I got headache with sound stuff in SuSE 11 SP3 using Audio device (Intel Corporation Haswell HD Audio Controller). The driver is "snd-hda-intel" as result in "lspci -vvv". I added a "model=generic" in the options but it returns "No elems found" in alsamixer. I tried also "model=auto" luckily it will open now the alsamixer but you can't adjust the mixer it will always be in zero value. Still no luck using "aplay" it always return an error result "ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave. aplay: main:590a; audio open error: No such file or directory" Anyone there knows the options for Haswell audio driver? Let me know if you need further details on my question. Thanks in advance.
