Describe the bug
Dear people,

Until now I was running LibreSpot and Scapcast (snapserver) on a raspberry 4.

Since I'm moving to proxmox (on a regular X86/AMD64 computer), I'm installing a Libresot + Snapcast dedicated Debain 11 LXC container.
What I did is that I copyed all the conf and services files from the raspberry to the Debian container.

But I'm facing an issue, here is what happens when I try to play a song to LibreSpot :

Here is how librespot is executed (as root, as you can see) :
root@snap:~# /usr/bin/librespot -v -H -n MultiRoom -N -b 320 --initial-volume 100 --backend pipe --device /tmp/snapfifo

And here is the / my failure :

I'm pretty sure this looks like a container related issue, but since I'm a bit of a newbie in the proxmox AND fifo and sound on Linux in general, well I'm trying here first.

Thanks for your kind help.

Hello kujac.
I run into a similiar issue. Just in case anyone ends up here looking for an answer. I solved my issue by ensuring fifo was not protected.

$> sysctl -a | grep -i protected
fs.protected_fifos = 0
fs.protected_hardlinks = 1
fs.protected_regular = 2
fs.protected_symlinks = 1

In my case, I had to change it in /usr/lib/sysctl.d/protect-links.conf on a rasbian

Super, thanks for the update. Hopefully @kujac can confirm and close this issue. This isn't a bug in librespot, if still having problems we can create a new GitHub discussion for running on containers.
