And finally my /etc/modprobe.d/alsa.conf file
| Code: |
# Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss

alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
# OSS/Free portion - card #1
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

## OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
options snd cards_limit=1

snd cards_limit doesn't seem to do anything on my machine, anyways I tried modifying alsa.conf multiple different ways, uncommenting and recommenting card #2, raising the cards_limit an then putting it back to default, nothing seems to work. ._. And yes I am using the nvidia proprietary driver.[/code] |

Hi
did you use the Gentoo driver release ?
Try using the Nvidia Driver for Linux, install...... but CLOSE ALL X11 Sessions (Runlevel)
Run than nvidia-xconfig
start your X11 and Gui
Use the Nvidia Gui and select the needed Resolution for you first/second Screen......
Often there is Problem adressing Nvidia Chips correctly..... no idea why so
use alsa-mixer to set up HDMI Sound.....
it works, same here, thats it
Have Fun

Didn't do anything.
Alsa mixer still see's my HDA Nvidia card there, but it has no controls for it. In aplay -L it shows exactly what I copy pasted there. |

if there is nothing shown, your System - Kernel - dosnt know what it is and how to address 
Recompile your Kernel.....
Try your Luck, here it works |

You have an entry in the wiki that explains howto handle hmdi
But before reading it, raise your limit to enable the 2nd card |
