[edit] KDE 4使用錯誤的音效裝置

這不是一個錯誤(error)，而是一個設定問題。利用應用程式「系統設定」告訴KDE 4可用的音效卡（或偏好的如果有的話）。

[edit] /etc/asound.conf或~/.asoundrc未列出設備

Phonon 使用ALSA 1.0.14引入的功能找到這些設備。為了使用這一功能您需要在列表添加一個名字暗示。 例如：

hint {
    show on
    description "Name to display for the device"
}

一個完整的例子，增加了一個名為Phonon to your mixer的新的音量控制：

pcm.softvolPhonon {
    type softvol
    slave.pcm "default:CARD=0"
    control {
        name "Phonon"
        card 0
    }
    min_dB -51.0
    max_dB 0.0
    resolution 100
    hint {
        show on
        description "My Soundcard with extra Volume Control"
    }
}

[edit] You are using KDE 3 and you keep losing sound. Sometimes it works, sometimes it doesn't.

KDE 3.x uses the aRts sound system. In earlier versions there were a number of problems, but in recent years the only problem remaining seems to be that aRts hangs on to the sound system when it has finished with it. To cure this, use kcontrol > Sound & Multimedia. Towards the bottom of the General tab there is a setting for 'Auto-suspend if idle after:' Set this to 1 second.

[edit] You have multimedia keys but KDE doesn't recognise them

This link has a clear description of what one user did to make his Volume-up and Volume-down keys work.
