PulseAudio remaps GPU ports on boot and suspend

I am running arch on a system with an Nvidia GTX-1080, and have been running into an annoying issue. I am using 3 outputs (2 DP and 1 HDMI), and want audio to always come through one of the DP's. The issue is that the profile which corresponds to the desired port will randomly be either HDMI 0 or HDMI 3 on any given boot or wake from suspend. This issue also occurred nearly the same way on an AMD RX-470, so It is unlikely to be an Nvidia problem.

I can think of a couple solutions:
- Output audio to all ports simultaneously, if possible. It doesn't hurt in my setup to have audio going to the other 2 devices.
- Change pulse or ALSA configs to make the profile predictable
- Use a script to determine which profile is needed and switch to it

I would appreciate any pointers on how to fix this, it is quite annoying having to pull up pavucontrol every other time I want audio.

Thanks

Re: PulseAudio remaps GPU ports on boot and suspend

This sounds like those audio outputs are assigned in semi-random order by kernel modules..

please post output of :

$ lspci -knn
$ aplay --list-devices
$ aplay --list-pcms

(aplay comes with alsa-utils)

Also check https://wiki.archlinux.org/index.php/Ad … sound_card

Re: PulseAudio remaps GPU ports on boot and suspend

Picture is getting clearer.

HDMI and Display Port monitors combine audio and video in one connection.
Do the attached monitors also change their designation ?

Re: PulseAudio remaps GPU ports on boot and suspend

The monitors do not change designation, they are always on DP-3, DP-4, and HDMI-0.

Re: PulseAudio remaps GPU ports on boot and suspend

Mh yes, but do e.g. the monitor that's on dp-3 swap with the monitor that's on dp-4 ? FWIW to get an overview of pulse's representation, can you post

Re: PulseAudio remaps GPU ports on boot and suspend

I can confirm exactly same issue with pulseaudio outputs on my nVidia GTX 1080 Ti, I have 3 monitors connected by DisplayPort. Each time my computer start from suspend the sound comes randomly from one of my monitors speakers.
Addition:  Screen layout  of my desktop (wallpapers, icons, screen position, and etc) does not changing their place.

It does not. If it did I could regex it off xrandr. The audio device number changes independently of the display port number.
