1. nix-shell -p alsa-tools
2. hwmixvolume
3. /usr/bin/env: ‘python’: No such file or directory

Expected behavior

hwmixvolume starts

Metadata

Please run nix-shell -p nix-info --run "nix-info -m" and paste the result.

[user@system:~]$ nix-shell -p nix-info --run "nix-info -m"
 - system: `"x86_64-linux"`
 - host os: `Linux 6.0.10-lqx1, NixOS, 22.11 (Raccoon), 22.11.3042.5eb98948b66`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.11.1`
 - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`

This is stock 22.11 install with stock lqx (liquorix) linux kernel, nothing unusual. Using pipewire + alsa + plasma.

[AndersonTorres]

I am a bit concerned, this program is old and I don't believe it was "updated" for Python 3.

[AndersonTorres]

Please test and report!

[cx405]

@AndersonTorres well, sadly no change.

However, this is just the tip of the iceberg. As you suggested, the program itself might be outdated or needs research into dependencies:

Because "making this to run" clearly surpasses "maintaining the package", I don't want to pressure you fixing it. So best resolution may be leaving the issue out until someone can fix it.

[AndersonTorres]

Good to know. I will comment that particular program.

[AndersonTorres]

Solved as "wontfix" :)
