How to disable audio of only one HDMI / Displayport port?

ua flag

I have two monitors connected via Displayport to different ports of the same GPU. I want to permanently disable audio of one monitor, and keep audio in the other one.

Pavucontrol is very useful at disabling hardware entirely (i.e. the webcam's mic). But I cannot find a way to disable audio from Monitor 2 while keeping Monitor 1 intact.

I'm happy with PulseAudio's hot swapping and it works great when switching on & off the audio interface, headsets, and so forth. Disabling hot swapping is not an option.

Maybe a solution could be hardcoding every device output in /etc/pulse/default.pa, but this sounds (pun intended) overkill and a potential source of other problems. Any ideas?

Are the monitors daisychained?

No, the GPU has several Displayport ports and each monitor is plugged independently.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
