I'd check both alsamixer and pulsemixer to ensure the volumes on the device are correct; here's an older related post: Sound won't use line out anymore, only spdif via HDMI - how to fix this? - #6 by stephematician
It all looks promising so far, except for the Pro Audio profile. I assume we're stuck with that (you did not mention any other options).
That said, I have found an issue that has no solution for this particular card: Front panel doesn't work with ALC887-VD - I would add your own info to that issue (e.g. PipeWire 1.0.5, Ubuntu MATE 24.04 desktop, kernel version given by uname -r, and the specific hardware you are using).
If the volume settings look correct in alsamixer and pulsemixer, then we'll have to have a look at what PipeWire is doing wrong - and that might be easier to troubleshoot over with their experts.
