在Ubuntu 15.10中使用pulseaudio，我想將兩個不同的麥克風組合成一個接收器，並讓它們在兩個不同的輸出端上播放組合輸出。下面的腳本會完成第一部分（在網絡上找到它），但輸出似乎只能在單個輸出中播放。Pulseaudio - 組合麥克風在組合揚聲器水槽上播放輸出
做後面的步驟需要什麼？
#!/bin/bash
# Script to map two pulseaudio hardware input sources as mono inputs
# to left and right channel of a new loopback-sink respectively. This
# sink can be used e.g. to use VoIP or record two microphones seperately.
