I have connected TV to my PC thru HDMI port. Every time I turn on my PC i need to change in pavucontrol (in config tab) from (HDMI) to (HDMI 3). I wish to make a bash script which can change it for me.

Here's how it looks in pavucontrol:

Output of pacmd list_sinks command before and after change in pavucontrol:

How can I achieve that?

Each time you reboot Pulse Audio resets sound device to HDMI. In order for it to keep the setting at HDMI3 you need to tell it to stop automatically switching.

Disable automatic device switching

When signal is lost to during sleep or shutdown, Pulse Audio is automatically configured to activate the default source (your HDMI). Upon resume or restart the sound device is still on HDMI. To override this setting, tell Pulse Audio to never switch sound devices automatically:

  • edit the file /etc/pulse/default.pa
  • find the line load-module module-switch-on-port-available
  • insert a # at the beginning of the line to disable automatic port switching
  • save the file and reboot.

Instead of rebooting you can use pulseaudio -k to reload the configuration changes.

(The accepted answer fixes the user's specific problem, but does not answer the original question "how to edit PulseAudio configuration through a script")

To change the PulseAudio configuration via terminal use the command:

pacmd set-card-profile <card> <new-profile>

where <card> is the index or the name of the target card (HDA Nvidia in your case). To get the card and profile names use pacmd:

$ pacmd list-sinks
card: 1 <alsa_card.pci-0000_08_00.1>
...
  properties:
    device.profile.name = "hdmi-stereo" # Before
    device.profile.name = "hdmi-stereo-extra2" # After
...

$ pacmd list-cards
name: alsa_card.pci-0000_08_00.1
  ...
  Profile:
    output:hdmi-stereo: <display name>
    output:hdmi-stereo-extra2: <display name> # Target profile
...

In your case it would be:

pacmd set-card-profile alsa_card.pci-0000_08_00.1 output:hdmi-stereo-extra2
