[BUG] Macos Zero Volume

[Jac-Zac]

Read the FAQ first

• I have checked the FAQ but the issue is not covered

Description

When the volume is zero the output shows up as the max value (255) in Mac OS: 15.4.1.

This is the configuration:

    {
      "type": "sound",
      "key": "│ ├",
      "percent": {
        "type": 9,
        "green": 30,
        "yellow": 70, 
      },
      "format": "{name} ({volume-percentage})",
      "keyColor": "blue",
    },

I have initially tested it in the brew version and I got the problem also in the version build from source

Perhaps I'm doing something wrong. Or if there is already a way to fix it pls let me know. Thanks in advance
