How to disable hdmi card?

[deepakdeshp]

Hello,
I am running Mint 19.2 Linux. I want to disable the hdmi card listed below.

Code: Select all

cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xf0e60000 irq 44
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0e64000 irq 45

Pavucontrol looks like this.

As far as I know you can't. You can, however, change the order of sound cards (I think that's what you'd want) (link):

Determine module name to put as number one with the command:

Code: Select all

cat /proc/asound/modules

Example for output:

Code: Select all

0 snd_hda_intel
1 snd_usb_intel

Then edit, as root, the file /etc/modprobe.d/alsa-base.conf and add:

Code: Select all

options snd_usb_intel  index=0
options snd_hda_intel  index=1

Reboot.

Thanks but both the cards 0 and 1 are shown as the same.

Code: Select all

 cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel

Then, I think, you cannot disable the first: tey're both on the same sound chip (or: sound card). This is how the Intel sound chip shows up in my system:

Code: Select all

 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7c10000 irq 45

That is: both the PCH (analog?) and digital HDMI part on the same chip/device. I als have another old PCI sound card in my system that I've set as No. 1.
