OpenAL fails to find `libpulse.so` on NixOS

[Sciencentistguy]

Operating System

Linux (NixOS)

Version of PolyMC

Version 1.4.2 Git GITDIR-NOTFOUND

Version of Qt

Qt 5 (nixpkgs)

Description of bug

Minecraft has no audio. This can usually be worked around by using the system OpenAL, but since 1.19 this option has no effect (See https://github.com/PolyMC/PolyMC/issues/643).

Steps to reproduce

• Run NixOS
• Run minecraft 1.19.x
• No sound!

Suspected cause

OpenAL fails to find libpulse.so. This is

stacktrace:

This issue is unique

• [X] I have searched the issue tracker and did not find an issue describing my bug.

[DioEgizio]

I think that might be an issue with the nixpkgs package, can you try our flake?

[Sciencentistguy]

Ah! The newest version of the flake indeed does not have this bug. This must have been a recent fix, as I was actually previously using your flake, and in troubleshooting reverted to the nixpkgs version due to an unrelated bug causing sporadic segfaults.

Thanks!

[Sciencentistguy]

Well this is odd. When running polymc with nix run github:PolyMC/PolyMC, the bug is not present.

When installed (with home-manager's home.packages) either from the command-line polymc or from the desktop entry (through gnome) the bug is present, even with the newest flake version.

Interestingly, nix run nixpkgs#polymc does have the bug

Did you read the middle paragraph? @spikespaz. The bug is present with your flake, if it is installed. It appears that nix run is doing something differently with the flake.

The flake and nixpkgs provide different packages. This is why they behave differently.
