如何在同一声卡的两个输出（模拟和数字）上同时获得声音（来自 pulseadio）？

如何配置 pulseaudio 在单个声卡的数字和模拟输出上同时播放声音？

我的系统是 OpenSuse 11.4（已安装所有更新）。命令“播放-l“返回：

之前（在 OpenSuSE 11.3 中）我根本没有使用过 pulseaudio，并且通过以下方式获得了预期的结果/etc/asound.conf文件：

    type plug
    slave {
       pcm multi

         }
}

    slave.pcm "multi"

module-combine将允许您将音频散布到多个接收器。
