如何用 Corona SDK 制作包含音乐和声音开关的 2 个按钮？

我需要关于我的小部件开关按钮的帮助。我已经创建了 2 个开关按钮，用于音效和音乐开关，但问题是每次我关闭和打开音乐开关时，音乐（mp3 声音）都无响应，每次我开启或关闭音乐时它都在快速向前运行。下一个问题是每次我关闭声音开关时，它也会关闭音乐（mp3 声音）。 这是我的代码：

--utils.lua

local sounds = {}
sounds["select"] = audio.loadSound("sounds/select.mp3")
sounds["score"] = audio.loadSound("sounds/score.mp3")
sounds["incorrect"] = audio.loadSound("sounds/gameover.mp3")
sounds["clap"] = audio.loadSound("sounds/clapping.mp3")
sounds["music"] = audio.loadSound("sounds/gameMusic.mp3")

M.playSound = function(name)
    if sounds[name] ~= nil then
        audio.play(sounds[name])
    end
end

--Settings.lua

soundSwitchPressed = function(event)
local switch = event.target
utils.playSound("select")

if switch.id == "sound" then
    if switch.isOn == true then
        audio.setVolume(0)
    else
        audio.setVolume(1)
    end
end
end

musicSwitchPressed = function(event)
    local switch = event.target
    utils.playSound("music")

    if switch.id == "music" then
        if switch.isOn == true then
            audio.setVolume(0)
        else
            audio.setVolume(1)
        end

    end
end

local sound_switch = widget.newSwitch
    {
        left = _W-70,
        top = navBar.y + navBar.height/2 + 44,
        style = "onOff",
        id = "sound",
        x = 800,
        y = 960,
        onPress = soundSwitchPressed
    }
    sound_switch.xScale, sound_switch.yScale = 3, 3
    uiGroup:insert(sound_switch)

    local music_switch = widget.newSwitch
    {
        left = _W-70,
        top = navBar.y + navBar.height/2 + 44,
        style = "onOff",
        id = "music",
        x = 800,
        y = 1200,
        onPress = musicSwitchPressed
    }

    if audio.getVolume() == 0 then
        sound_switch:setState({isOn=false, isAnimated=false})
        music_switch:setState({isOn=false, isAnimated=false})
    else
        sound_switch:setState({isOn=true, isAnimated=false})
        music_switch:setState({isOn=true, isAnimated=false})
    end
end
