How to set up a sound card in Linux?

Question

linux

Laptop HP ENVY 15-j004er Runs
Debian 8 xfce.
There is sound, but NOT from the desired sound card, but by default from the Intel sound card.
The sound card under Windows was signed like this (you need this card to work): idt high definition audio codec.
driver: stwrt64.sys
At the moment alsamixer shows and sees only 1 card.
PulseAudio
Sees one penalty too.
lspci
(white line) also nothing interesting was found.

Answer 1

$ cat ~/.asoundrc

pcm.!spdif {
     type hw
     card 1
     device 0
}
pcm.!default {
     type plug
     slave {
           pcm "spdif"
     }
}

Where type hw, card 1 and device 0 are yours respectively.
By the way, I have the same: "00: 1b.0 Audio device: Intel Corporation"
