Hi everyone,
I'm running Arch Linux with PipeWire and I can’t get audio output over the HDMI/DisplayPort device. The device and corresponding sink are detected, and I made sure it was unmuted as well, but I don't seem to be able to make it emit sounds.
Bluetooth audio works, and so does the 'Build-in Audio' when I plug a wired headset to my 3.5mm audio jack. This makes me think its something specific to the HDMI/DisplayPort device, perhaps something related to the Nvidia driver. In case it matters I have an old GTX1080 GPU.
I recently upgraded to Nvidia proprietary driver 580.76.05-4. I know the audio over DisplayPort was working fine at some point in the past, but I can't say for sure whether it was working right before upgrading since I switched from HDMI to DisplayPort just after the upgrade due to display issues with HDMI. Unfortunately I can't test if the audio works over HDMI either due to these issues (no video output).
In any case, I believe the audio device for HDMI & DisplayPort is the same.
Some info:

Just out of the blue, have you tried checking with alsamixer? wireplumber says Vol 1.00 and unmuted but just for the sake of it.
And the output of pw-link -l when you play audio please

I experienced the same issue recently, with HDMI audio previously working perfectly. My GPU is 1080 TI, and I'm using an active HDMI cable (15m). Audio over the cable works fine from my laptop. I'm using sway.
Strangely, if I toggled the HDMI display on and off many times, sometimes the sound started working.
I first experienced this with driver version 580.76.05-4. This issue also happens with the current arch version of the driver, 580.82.07-1.
FIX: I downgraded my drivers by running
sudo downgrade nvidia-dkms nvidia-utils lib32-nvidia-utilsUsing downgrade from AUR. I installed version 575.64.03-1 of all packages, since that is what I was using previously. Also added these packages to IgnorePkg for now.

Thank you both for the replies, and apologies for the delay in the response.
I've checked with alsamixer, I see everything unmuted there as well. Here's the output of pw-link -l when playing audio in Firefox:
$ pw-link -l
alsa_output.pci-0000_01_00.1.hdmi-stereo:playback_FL
|<- Firefox:output_FL
alsa_output.pci-0000_01_00.1.hdmi-stereo:playback_FR
|<- Firefox:output_FR
Firefox:output_FL
|-> alsa_output.pci-0000_01_00.1.hdmi-stereo:playback_FL
Firefox:output_FR
|-> alsa_output.pci-0000_01_00.1.hdmi-stereo:playback_FRahartik's comment made me think about the cable, so I tested replacing the DisplayPort cable with an HDMI. Surprisingly enough audio works with HDMI, but not with DisplayPort.
Is there a separate configuration step needed to route audio through DisplayPort instead of HDMI? Or should the device appear the same in PipeWire for both?
