Code:
flammenflitzer linux # lspci -v | grep -i audio
00:0f.1 Audio device: nVidia Corporation MCP55 High Definition Audio (rev a2)

snd_page_alloc          7002  2 snd_hda_intel,snd_pcm

Ich möchte die Reihenfolge der Karten festlegen, da es sonst Probleme mit Pulseaudio gibt.
Wie trage ich das in die /etc/modprobe.d/alsa.conf ein?
Code:

1 Intel Audio snd_hda_intel snd_hda_codec snd_hda_codec_realtek (OnBoard Soundchip)
2 Intel Audio snd_hda_intel snd_hda_codec_hdmi (Nvidia HDMI)
2 snd_usb_audio (WebCam)

Code:
options snd cards_limit=3
option snd_hda_intel index=0
option snd_hda_intel index=1
option snd_usb_audio index=2
? Wie unterscheide ich die beiden snd_hda_intel ?

Schau mal ob dir http://alsa.opensrc.org/MultipleCards#Multiple_devices
weiterhilft.

Habe ich gelesen. Komme ich nicht mit klar.
Ich probiere jetzt
Code:
options snd_hda_intel index=0,1
options snd_usb_audio index=2
Zutreffend wäre
Code:
Loading the kernel modules for multiple cards

Frank Barknecht offered this dual card configuration example to the alsa-devel mailing-list.

See TwoCardsAsOne for an idea for setting up an .asoundrc to use two cards together. Read chapter below (a code fix).

# START
alias char-major-116 snd ???
alias char-major-14 soundcore ???
options snd snd_major=116 snd_cards_limit=3 # snd_device_mode=0660 snd_device_gid=29 snd_device_uid=0 ich denke, das brauche ich nicht

# HDA NVidia ALC888
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss 
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss 
alias sound-service-0-12 snd-pcm-osshree 

# HDA NVidia HDMI
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
#alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
#alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss

# USB-Audio
alias sound-slot-2 snd-card-2
alias sound-service-1-0 snd-mixer-oss
#alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
#alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss

#alias snd-card-0 snd-card-ice1712
alias snd-card-0 snd_hda_intel
options snd-card-hda-intel index=0

#alias snd-card-1
alias snd-card-1 snd_hda_intel
options snd-card-hda-intel index=1

#alias snd-card-2
alias snd-card-2 snd_usb_audio
options snd-card-usb-audio index=2

# END

aber wie unterscheide ich ALC888 und HDMI ?

Ist das der selbe Thread wie im Gentoo.de Forum? Meinte da einen ähnlichen gesehen zu haben.

Allgemein:
Wenn du zwei Soundkarten hast, die das selbe Modul verwenden UND gleich heißen (NVidia, NVidia), dann hast du kaum eine Chance nur mit der modprobe.conf

Code:
parm:           index:Index value for Intel HD audio interface. (array of int)
parm:           id:ID string for Intel HD audio interface. (array of charp)
parm:           enable:Enable Intel HD audio interface. (array of bool)
parm:           model:Use the given board model. (array of charp)
parm:           position_fix:DMA pointer read method.(0 = auto, 1 = LPIB, 2 = POSBUF, 3 = VIACOMBO). (array of int)
parm:           bdl_pos_adj:BDL position adjustment offset. (array of int)
parm:           probe_mask:Bitmask to probe codecs (default = -1). (array of int)
parm:           probe_only:Only probing and no codec initialization. (array of int)
parm:           single_cmd:Use single command to communicate with codecs (for debugging only). (bool)
parm:           enable_msi:Enable Message Signaled Interrupt (MSI) (int)
parm:           align_buffer_size:Force buffer and period sizes to be multiple of 128 bytes. (bool)
parm:           snoop:Enable/disable snooping (bool)


Die asound.conf hilft dir auch nur, wenn die Karten einen unterschiedlichen Namen haben. Dann kannst du sie anstatt der Nummer (hw:0,0) mit dem ID String ansprechen (z.B. hw:NVidiaHDMI,0).

Den kannst du aber selbst festlegen in dem du eine udev Regel erstellst wie im verlinkten Wiki Artikel beschrieben:
http://alsa.opensrc.org/Udev

Erfordert halt ein bisschen Einlesearbeit.
