[SOLVED]How can I completely remove Nvidia HDMI soundcard?

Hi everyone.

I have tried to fix this specific problem for several days now and I can't seem to get it to work. The wiki and google have not been able to help me.

I am using Pulseaudio and Alsa.

I have 3 different sound cards:

[johan@archlinux ~]$ cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfbff8000 irq 50
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf9ffc000 irq 17
 2 [Headset        ]: USB-Audio - SB WoW Wireless Headset
                      SB WoW Wireless Headset SB WoW Wireless Headset at usb-0000:00:1a.0-2, full spe

I don't use the Nvidia card at all and would like to remove it from the equation. In most cases this is done by blacklisting the corresponding module in rc.conf, but both card 0 and 1 uses the same moduel.

[johan@archlinux ~]$ cat /proc/asound/modules 
 0 snd_hda_intel
 1 snd_hda_intel
 2 snd_usb_audio

So, if I disable the snd_hda_intel module, I assume none of them will work.

Why do I want to remove the Nvidia card?

Well, I like to change the output sink with a script so I can easily keybind it. The script I used to use looks like this:

#!/usr/bin/env bash

sinks=($(pacmd list-sinks | grep index | \
    awk '{ if ($1 == "*") print "1",$3; else print "0",$2 }'))
inputs=($(pacmd list-sink-inputs | grep index | awk '{print $2}'))

[[ ${sinks[0]} = 0 ]] && swap=${sinks[1]} || swap=${sinks[3]}

pacmd set-default-sink $swap &> /dev/null
for i in ${inputs[*]}; do pacmd move-sink-input $i $swap &> /dev/null; done

I copied this script from somewhere a time ago and it has been working fine when using debian. With Arch it does not.

Does anyone know howto remove my hdmi sound card or change the script so that it switches between just my onboard card and my usb headset? If there is a way to send all sound to all 3 cards, that would be another solution.

Re: [SOLVED]How can I completely remove Nvidia HDMI soundcard?

Is it possible to force the nvidia sound card to use another module, and then disable that module? Grasping for straws...

Re: [SOLVED]How can I completely remove Nvidia HDMI soundcard?

Ok.

So the solution was kind of simple.

I simply installed pavucontrol and turned of the hdmi card in the interface. I then added the following to my /etc/pulse/default.pa:

load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe

Then I was able to use the combined channel for the two cards that was left after disabling hdmi. I switched from Xine to Gstreamer in Phonon backend and I don't get any lag with this solution. This way I don't even have to use a macro to switch between output sinks.

Re: [SOLVED]How can I completely remove Nvidia HDMI soundcard?

I also tried to do this.
First I tested a modalias in modprobe.conf, that didn't work.
I tried to create a udev rule to disable the device, but that didn't work because "ignore_device" and "last_rule" don't work anymore.

This is how I fixed it now:

Find the pci id with:

lspci | grep -i audio

Find the correct folder

find /sys/devices -name *01:00.1
/sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/

And add this to the /etc/rc.local

echo 1 > /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/remove

Re: [SOLVED]How can I completely remove Nvidia HDMI soundcard?

Does this work for systemd? I tried this with a new arch installation and didn't work...
Any help? TIA
