Since libavresample was deprecated from ffmpeg, and something went wrong with the rate plugin's config parser, digital surround sound output has been broken.

There is a workaround, packaged herein.

You'll need to install libavresample and alsa-plugins built against it for the lavrate plugin, then alsa-lib-a52pcm to work with the well known configuration.

$ git clone https://aur.archlinux.org/libavresample
$ cd libavresample/
$ makechrootpkg -c -r $CHROOT
# pacman -U --asdeps libavresample-4.3.1-1-x86_64.pkg.tar.zst
$ cd ../
$ git clone git://git.archlinux.org/svntogit/packages.git --{single-,}branch {packages/,}alsa-plugins
$ cd alsa-plugins/trunk/
$ makechrootpkg -c -r $CHROOT -I ../../libavresample/libavresample-4.3.1-1-x86_64.pkg.tar.zst
# pacman -U alsa-plugins-1\:1.2.2-2-x86_64.pkg.tar.zst
$ cd ../../
$ git clone https://aur.archlinux.org/alsa-lib-a52pcm
$ cd alsa-lib-a52pcm/
$ makechrootpkg -c -r $CHROOT
# pacman -U --asdeps alsa-lib-a52pcm-1.2.4-1-x86_64.pkg.tar.zst

Note: If audio is again lost after an upgrade, repeat.

One more thing, to save your sanity, you may want to prevent pacman from automatically upgrading alsa-plugins and alsa-lib:

in /etc/pacman.conf

IgnorePkg = alsa-plugins alsa-lib

@xtc0r

Looks like you found out about devtools.

You can delete the chroot, or leave it there and maintain it for future package builds.

[EDIT2] 5.1 is working again! Thank you! Can I delete the CHROOT folder or is this still needed after installation?

[EDIT] Seems for manjaro some things are diffrent. I followed this thread and could install it: https://forum.manjaro.org/t/solved-please-help-installing-alsa-lib-a52pcm/35832/5

Hi, I'm just a linux noob trying to get 5.1 sound via SPDIF back.

I'm on manjaro linux.

I could execute 

$ git clone https://aur.archlinux.org/libavresample
$ cd libavresample/

But 

makechrootpkg -c -r $CHROOT

gives: Command not found. Or is the complete command

makechrootpkg -c -r $CHROOT pacman -U --asdeps libavresample-4.3.1-1-x86_64.pkg.tar.zst

This gives me: Package couldn't be found or read.

Why is 5.1 Sound so damn difficult on linux?
