In my case, there seems to be an issue with pipewire using too many file
descriptors:

I was able to get my sound working by logging out and back in.
After I got it working, I ran this:
lsof -p3468 | wc -l
1013
I wonder if it was around 1024 before I logged out..?
The open file limit for the process is: 1024
This explains why "killall pipewire-pulse" would get my sound working
again for a single application... It was freeing up one file descriptor.
Is this a pipewire bug, a tas2781 driver bug, or a bit of both? I think
if this were a general pipewire issue, we'd be hearing a lot more
complaints...
After logging in, I tried this:
systemctl restart --user pipewire
This resulted in a new pipewire process and only 25 open file
descriptors. Wonder if this would have fixed the issue without logging
out? Something else to try next time.
Next time this happens, I'll see if I can figure what all the file
descriptors are for.
For others having this or similar trouble, see if you're having similar
issues with pipewire (or perhaps even pulse) and file descriptors.
/var/log/syslog is another valid place to check for these messages (at
least on Ubuntu).
