@kwa71 OP
of you are still having problems with your sound card running ALSA.

this link tells how to with ALSA setting it up and checking things and writing your conf and setting devices.

Mine:
get your information using these commands.

Code:

(userx@SlackO⚡️~)>>$ aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Code:

[userx@USB16Void64Linux ~]$ cat /proc/asound/card*/codec* | grep Codec
Codec: IDT 92HD81B1X5
Codec: LSI Generic HDMI
Codec: ATI R6xx HDMI

something I on how to set your device by the name of your device not mine in this example. I had to create a file called . /etc/modprobe.d/snd-hda-intel.conf then added my information within it.

Code:

then you could assign card 1 to index=0 with /etc/modprobe.d/snd-hda-intel.conf containing

alias char-major-116 snd
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-hda-intel

options snd-hda-intel id=Generic_1 index=0
options snd-hda-intel id=Generic index=1

Code:

options snd-hda-intel model=auto
options snd-hda-intel id="HDA Intel PCH" index=0
options snd-hda-intel id="HDA ATI HDMI" index=1

Code:

    [userx@USB16Void64Linux ~]$ aplay -l
    ----List of PLAYBACK Hardware Devices-----
    card 0: PCH [HDA Intel PCH], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog]
    Subdevices: 0/1
    Subdevice #0: subdevice #0
    card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

    GNU nano 2.7.1 File: snd-hda-intel.conf

    options snd-hda-intel model=auto
    options snd-hda-intel id="HDA Intel PCH" index=0
    options snd-hda-intel id="HDA ATI HDMI" index=1

that is what I did from an install I had a while back. I had to dig up that up for ya. I hope it helps.
